Co-Founder E-Learning Used the software for: Less than 6 months ### "Simple, effective tool for paid bookings" March 26, 2026 4.0 Overall, CalID is a strong option if you want a clean, no-fuss system to manage paid bookings. It keeps things simple and for many use cases, that’s exactly what you need. Pros I’ve been using CalID for managing paid calls, and overall it’s been a really helpful addition to my workflow. What I value most is the pay-first-then-book flow. It’s made a noticeable difference in the quality of booking, people who schedule are more committed, which has reduced no-shows and unnecessary back-and-forth. In terms of ease of use, the platform is quite intuitive. Setting things up didn’t take long, and the interface is clean without feeling overwhelming. For someone who doesn’t want to spend hours figuring out a tool, this is a big plus. When it comes to booking and scheduling it does a solid job. Everything is streamlined in one place, which makes it easier to manage calls without juggling multiple tools. It’s especially useful if you’re offering paid consultations or sessions. From a value for money perspective, I think it delivers well for what it promises, particularly if your priority is a simple, reliable system for paid bookings. Cons I found the customisation and automation options a bit limited. If you’re someone who wants more control over reminders or deeper integrations, you might feel that gap. Switched from [Calendly](https://www.capterra.com/p/148036/Calendly/) Payment intergration. Needed to intergrate with a India based payment tool Review Source Response from OneHash April 2, 2026 Thanks, Reethu. Glad the pay-first booking flow is helping reduce no-shows and keep things streamlined. We appreciate your feedback on customization more flexibility and integrations are on our roadmap. RW Rushikesh W. Founder Marketing and Advertising Used the software for: 6-12 months ### "Efficient and Scalable Team Scheduling Platform" April 21, 2026 5.0 My overall experience with Cal.com has been positive. It simplifies scheduling, supports team-based bookings, and reduces manual coordination. Once set up, it runs smoothly and efficiently for daily use. Pros The biggest advantage of Cal.com is its flexible team scheduling and automation capabilities. It allows multiple team members to operate under a single booking system, with features like round-robin assignment, customizable availability, and seamless integrations. This significantly reduces manual coordination, prevents scheduling conflicts, and improves overall efficiency. Additionally, the platform offers a high level of customization, making it well-suited for scaling teams and more complex scheduling workflows. Cons The least favorable aspect of Cal.com is that the initial setup and configuration can be somewhat complex for new users. While the platform is highly flexible and powerful, it requires time and careful setup to fully configure team scheduling, routing, and integrations compared to simpler plug-and-play alternatives. Switched from [Calendly](https://www.capterra.com/p/148036/Calendly/) I switched from Calendly because Cal.com offered more flexibility for managing team scheduling and customization. It fit my workflow better and gave more control over availability, booking logic, and integrations compared to Calendly. Review Source Response from OneHash April 24, 2026 Appreciate it, Rushikesh. Happy Cal ID is streamlining your team scheduling. Onboarding improvements are on the way. AJ Ayodeji J. Co-founder Financial Services Used the software for: Less than 6 months ### "Fast, reliable KYC with room for deeper transparency" April 2, 2026 5.0 Overall, a solid and reliable identity verification solution for startups. It balances speed and usability well, making it suitable for MVP and early scaling stages. However, improvements in documentation, error visibility, and pricing clarity would strengthen the developer and product experience. Pros Fast and straightforward verification flow with minimal friction. The interface is clean, onboarding is intuitive, and API integration is relatively easy to implement for early-stage products. Cons Limited transparency on edge-case failures and retry logic. Documentation could be more detailed around error handling, and pricing/credit usage is not always clear upfront. Review Source Response from OneHash April 9, 2026 Appreciate your review, Ayodeji. Great to know Cal ID supports your workflow, we value your input on pricing and docs. Keshave L. Founder Professional Training & Coaching Used the software for: Less than 6 months ### "Clean UI, Great Workflows, and Zero Scheduling Friction" April 2, 2026 5.0 Setting up Cal ID was incredibly fast; the Google Calendar sync worked on the first try without any glitches. It feels like a tool built for the modern consultant who wants a "set and forget" system that doesn't sacrifice brand aesthetics. For anyone tired of the limitations on free versions of other scheduling software, Cal ID is a breath of fresh air. Pros What stands out most about Cal ID is the clean, minimalist user interface. Unlike other tools that feel cluttered, the booking pages here look very premium and professional, which is essential for my brand. I also love that features which are usually behind a paywall—like unlimited event types and Razorpay/Stripe integrations—are available here. The WhatsApp integration is a game-changer for reducing no-shows. Cons Currently, there isn't a dedicated mobile app, so I have to manage everything through the mobile browser. It works perfectly fine, but a native app for quicker push notifications would be a great future addition. Also, I’d love to see even more deep-level CSS customization for the booking pages. Alternatives considered [Acuity Scheduling](https://www.capterra.com/p/191978/Acuity-Scheduling/) Reason for choosing Cal ID I considered Acuity, but found the setup process to be overly complex and the user interface felt a bit dated for my needs. Cal ID struck the perfect balance: it has the deep functionality of Acuity (like payment integrations and robust reminders) but maintains the simple, '5-minute setup' experience of Calendly. For a business owner, the speed of deployment and the clean, minimalist booking page for my clients were the deciding factors. Switched from [Calendly](https://www.capterra.com/p/148036/Calendly/) While Calendly is the industry standard, I found their free tier far too restrictive for a growing consulting business. Being limited to only one event type was a major bottleneck. I switched to Cal ID because it offers Pro-level features—like multiple event types, automated workflows, and custom branding—without the immediate high monthly overhead. The interface also feels more modern and aligned with my brand's aesthetic. Review Source Response from OneHash April 9, 2026 Thank you, Keshave. We're thrilled Cal ID delivers a premium, frictionless scheduling experience for your brand. Rohit J. Partner Financial Services Used the software for: Less than 6 months ### "A good scheduling system" April 26, 2026 4.0 Great. Been using it for a week and have understood most of the features. Definite scope for improvement, but a much-needed and valuable app. Pros The ability to connect all emails together and provide a common available slot. Ability to automate a few workflows, as well as premium features, in base versions Cons UI is a bit outdated and can be improved. The preview of the calendars do not show the branding properly. Minor issue in the Outlook calendar invite: meetings are showing as 0 mins. Alternatives considered [Zoho Meeting](https://www.capterra.com/p/202121/Zoho-Meeting/)[Google Calendar](https://www.capterra.com/p/213340/Google-Calendar/) Reason for choosing Cal ID Ability to add multiple calendars and an easy booking interface Review Source Response from OneHash May 6, 2026 Thanks for sharing, Rohit glad you’re finding it helpful; we’ve taken note of the issues you mentioned and will refine them.

VR Verified Reviewer EVP - Learning Transformation and AI Strategy E-Learning Used the software for: Less than 6 months ### "One of the best Scheduling Apps today" April 10, 2026 5.0 It is a feature rich scheduling application. I have already used it for more than a month and found to be extremely useful. It has helped me streamline bookings for my meetings. Pros It is very easy to setup and get started. It has rich features to configure events as per your preference. Cons More features and settings offer flexibility but also mean one has to learn a lot more over time to take full advantage. Switched from [Calendly](https://www.capterra.com/p/148036/Calendly/) This one looked more richer in terms of features Review Source Response from OneHash April 15, 2026 Thank you. We're pleased Cal ID makes scheduling simple while offering advanced options. Prashant C. Founder Hospital & Health Care Used the software for: I used a free trial ### "Perfect Scheduling Partner " April 1, 2026 5.0 Highly positive, particularly in how it bridges the gap between scheduling and professional brand identity. Pros What I like most about Cal ID is how it transforms a basic scheduling task into a professional brand Cons What I liked least was the limited flexibility in the layout design. Customization options are needed. Switched from [Calendly](https://www.capterra.com/p/148036/Calendly/) Economical and easy to use with branding integration. Review Source Response from OneHash April 9, 2026 Thank you, Prashant. We’re pleased Cal ID blends scheduling with branding for your business. Surinder Pal S. GM Sales Computer Software Used the software for: Less than 6 months ### "Worth using! " April 9, 2026 5.0 Pros Using CalID from a week and have had good experience so far. They have almost all features that Calendly has and that too for free. Yes, paid once are good too when you have a team Cons Nothing that I can see here. So far it's good on what all I have explored with CalID in comparison with other platforms. Switched from [Calendly](https://www.capterra.com/p/148036/Calendly/) It is cost-effective and easy to use, so moved! Review Source Response from OneHash April 15, 2026 Thanks, Surinder Pal. Happy to hear Cal ID offers the features you need with ease of use. Rajeev K. Director Information Technology and Services Used the software for: I used a free trial ### "“Efficient and User-Friendly Appointment Management Tool with Minor Improvements Needed”" April 25, 2026 5.0 Overall, my experience with Cal ID has been positive. It helps streamline appointment scheduling and improves operational efficiency. While there are minor areas for improvement, it is a reliable tool for managing bookings and customer interactions. Pros The best part is its easy-to-use interface combined with powerful appointment scheduling and reminder features. It simplifies daily operations significantly. Cons There are occasional bugs and limited customization options in some areas. Also, more payment integrations would be beneficial. Review Source Response from OneHash May 6, 2026 Appreciate your insights, Rajeev great to know it’s simplifying scheduling. we’re working on the areas you mentioned. JS Joel S. Professor of Accounting Education Management Used the software for: Less than 6 months ### "Cal.id holds it’s Own" November 12, 2025 4.0 I use it to schedule appointments with my students for advising and provide my help with course content. I schedule both in person meetings and online meetings. Overall, it feels like a time‑saver that “just works” once it’s set up: sharing a link lets people book themselves, reminders nudge them to show up. It looks clean and professional to students, the free version is generous, and it connects to common tools like your calendar and video calls without much fuss. There are a few rough edges—some settings take a moment to find and a couple of advanced options aren’t as deep as older tools—but for everyday scheduling, it’s smooth, simple, and easy to recommend to non‑tech folks. Pros Cal ID makes scheduling simple: share a link, people pick a time that works, and you’re done—no back‑and‑forth emails or tech hassle. It’s free to start and lets you make as many booking links as you want, so it fits everyone from solo tutors to small teams. If you work with others, it can automatically spread meetings across team members so no one gets overloaded. Your booking page looks polished and professional, and reminders help folks show up on time. It also plays nicely with common tools like your calendar and video calls, so setup is quick and you won’t need a tutorial to get going. Cons Here are the downsides: It’s still new, so you may run into rough edges or features that feel a bit basic compared to long‑standing tools. The setup is simple for basics, but finding and fine‑tuning the “extra” settings can take some trial and error. Some advanced options and team workflows may require upgrading or don’t go as deep as larger, older platforms. Integrations generally work well, but like any scheduler, occasional hiccups can happen with video links or calendars, so it’s smart to test your must‑have connections before rolling it out widely. And if you prefer a mobile app with rich analytics and detailed reports out of the box, you might find Cal ID lighter than you’d like. Alternatives considered [Calendly](https://www.capterra.com/p/148036/Calendly/) Reason for choosing Cal ID You get more in the free version of Cal.id over Calendly Review Source Response from OneHash November 27, 2025 Thanks for the detailed review, Joel. Great to hear Cal ID is simplifying your student scheduling and working smoothly day-to-day. Your insights on rough edges and advanced features are noted and will guide our upcoming improvements. MA Mehdi A. Founder and CEO Marketing and Advertising Used the software for: Less than 6 months ### "Cal ID coming in STRONG to disturb the market!" November 16, 2025 5.0 I switched from Calendly a few months ago because I didn't want to keep paying for features I barely used. Cal ID has been a game changer. My clients love how easy it is to book time with me, and I love that I can see everything in one place. The calendar integration worked perfectly with my Google Calendar, and I haven't had any issues with double bookings or anything like that. Overall, I'm really happy with Cal ID. It does exactly what I need it to do without all the bloat or the price tag. Highly recommend it if you're looking for a solid Calendly alternative. Pros Honestly, the ease of use is what sold me. I've tried a few different scheduling tools over the years (Calendly, TidyCal, Cal, etc.) and Cal ID just feels smoother. Setting up different event types was way more intuitive than I expected, and I love that I can customize the colors to match my branding without paying for some premium tier. The free plan has pretty much everything I need, which is rare these days. Cons Not really a con, but I wish they had a mobile app. Right now I'm just using the web version on my phone, which works fine, but a dedicated app would be nice. Also, the interface can feel a bit overwhelming at first with all the customization options—there's almost too much flexibility, if that makes sense. But once you figure out what you need, it's great. Switched from [Calendly](https://www.capterra.com/p/148036/Calendly/) I needed something that will help me synch multiple calendars without costing me an arm and a leg to do so. Review Source Azzam S. Founder E-Learning Used the software for: 6-12 months ### "CAL ID - LifeSaver App" December 23, 2025 5.0 My overall experience is fantastic as they have provided the best customer support, great pricing and their attention to detail is fantastic Pros The app is super efficent and make my life easier with the emmbedding solution and modal integrations for our web-apps and mobile app also! Cons Not have their own calender to use and extra integrations to Zoho app as that will be much easier to connect. Switched from [Calendly](https://www.capterra.com/p/148036/Calendly/) They had a very bad customer service and their integration was not working. Review Source Response from OneHash January 6, 2026 We appreciate your feedback, Azzam. It’s rewarding to hear that Cal ID’s efficiency, pricing, and attention to detail are simplifying your scheduling needs. Royston S. QA Information Technology and Services Used the software for: 6-12 months ### "Platform easily integratable." November 4, 2025 5.0 Pros Its easy to use platform and easily integrates with viasocket AI powered automation platform. I am amazed with the UI and it's easy. Cons I find the integrations on the payment gateways are fewer. Need the other payment gateways to support UPI in India. Switched from [Calendly](https://www.capterra.com/p/148036/Calendly/) Pro Pricing and the API customisation features. Review Source Response from OneHash November 27, 2025 We appreciate your feedback, Royston. It’s great to know the platform and integrations meet your needs. UPI and additional payment options are priorities on our roadmap. Abhilasha S. CHIEF STRATEGY OFFICER Information Technology and Services Used the software for: Less than 6 months ### "Great for Automated, No-Fuss Booking" December 18, 2025 5.0 Smooth, professional booking experience that has made scheduling easier and more reliable, especially when dealing with many external stakeholders and different meeting types. It reduces back-and-forth coordination, keeps calendars in sync, and supports automation and paid meetings in a way that feels powerful Pros Simple, professional booking experience and powerful automation that removes back-and-forth scheduling. Cons Limited customization for branding and advanced workflows compared to heavier enterprise tools. Learning curve for setting up more complex automations and integrations. Switched from [Calendly](https://www.capterra.com/p/148036/Calendly/) Cal ID offers better customization, smoother multi-calendar handling, and fits our sales workflow much better Review Source Response from OneHash January 6, 2026 Thank you for sharing your experience, Abhilasha. We’re happy Cal ID is delivering a professional, no-fuss booking experience that fits your workflow needs. VR Verified Reviewer CEO Information Technology and Services Used the software for: Less than 6 months ### "Great product, a Calendly and Cal.com alternative that you can rely on." December 1, 2025 4.0 Overall experience with CalID is good the team has still things to work on and fix. Hope they does that soon enough so that i could unleash the full potential of this platform for my business Pros I was able to connect my multiple calendars and manage it all in one place. It made my appointment booking smooth and seamless. Ability to connect multiple calendars and video conferencing apps enhanced the way how i schedule meetings with my clients. Cons I had issues connecting my zoho calendar but i was able to connect Google and Outlook calendars. I would like to connect my zoho calendar as well inorder to completely integrate my scheduling workflow into cal id. Hope the team will fix this soon. Switched from [Calendly](https://www.capterra.com/p/148036/Calendly/) First of all the price. Calendly was too expensive. Cal.com even if selfhosted didn't provide teams option. Review Source Response from OneHash December 15, 2025 Appreciate your feedback. Happy to hear Cal ID is streamlining your bookings, and your note on Zoho integration is well noted by our team. HM Hrishiraj M. CEO Staffing and Recruiting Used the software for: 6-12 months ### "Easiness of Booking" November 17, 2025 5.0 Its super easy for me and my customers to book a call using Cal ID and it gives us flexibility to choose the meeting platform which is a plus. Along with that, customizable colors as per the brand colors and custom header banner is really unique feature. Pros The customization features and feasibility to connect multiple meeting platforms was helpful for my business and for my customers. Cons I havent found anything yet, that I can mention here. Still exploring the platform. Nothing as of now. Switched from [Calendly](https://www.capterra.com/p/148036/Calendly/) Less customization and higher price was the reason. Review Source Response from OneHash December 5, 2025 Hi Hrishiraj, thanks for the kind review. Great to hear that our customization options and flexible meeting integrations are adding value to your workflow. Brandon S. Founder Marketing and Advertising Used the software for: Less than 6 months ### "Switched and not looking back. " December 3, 2025 5.0 My overall experience with Cal ID has been great. It’s one of those tools that quietly cleans up your workflow and makes you wonder why everything else feels so clunky. Setup was quick, the interface is clean, and the automations save me real time week to week. It’s become a core part of how I manage my schedule and how I present my brand to others and I switch all my links from another tool. Pros Cal ID is super minimal and just beautifully designed. People literally stop me to ask what calendar tool I’m using, which says a lot. It gives me everything I need from a scheduling platform, from automations to workflows, without feeling bloated or complicated. Cons I honestly can’t think of any right now, but I’ll update this and write something here when I do. It's honestly gets the job done. Switched from [Calendly](https://www.capterra.com/p/148036/Calendly/) The value and ease. It was a no brainer in my opinion. Review Source Response from OneHash December 15, 2025 Thanks for sharing, Brandon. It’s great to hear Cal ID’s simplicity and ease are saving you time and becoming a core part of your scheduling. DC Deeip C. Founder Marketing and Advertising Used the software for: I used a free trial ### "Clean, Fast, and Founder-Friendly Scheduling Tool" January 20, 2026 5.0 My overall experience has been very positive. Cal ID makes scheduling simple, fast, and professional. It removes the back-and-forth of setting up meetings and provides a clean booking experience for both me and the people booking calls. It feels reliable, well-designed, and built with a strong focus on usability. Pros The UI is very clean and modern, setup is extremely quick, and the overall experience feels smooth and lightweight. I especially like how simple it is to create and share a scheduling link without unnecessary complexity. It feels built for founders and professionals who want speed and clarity. Cons Since the product is still growing, some advanced customization and deeper integrations could be expanded over time, but nothing that blocks the core use case. Switched from [Calendly](https://www.capterra.com/p/148036/Calendly/) I wanted a simpler, faster, and more modern scheduling experience. Cal ID feels lighter, cleaner, and more founder-focused compared to Calendly, with a better UI and a more straightforward setup process. Review Source Response from OneHash January 29, 2026 Thanks, Deeip. It’s awesome to hear Cal ID’s clean design and quick setup are making scheduling smooth and professional for you, your feedback on customization helps guide our ongoing improvements. SKM Suresh Kumar M. Senior Developer Computer Software Used the software for: I used a free trial ### "Great tool → Not a full platform foundation" April 21, 2026 5.0 MVP / early-stage booking system Quick integration without building scheduling from scratch Solo or small team service providers Pros 1\. Very easy to use Clean UI, minimal setup Clients can book slots without back-and-forth emails Works well even for non-technical users 👉 This is one of its strongest points — quick adoption. 2. Free with “premium-like” features Unlimited meetings Team scheduling & routing Custom branding options No heavy paywalls like competitors 👉 Huge advantage if you’re cost-conscious (which you mentioned earlier). 3. Solid scheduling automation Auto time-slot matching Avoids double bookings Automatic reminders (email/WhatsApp) Different event types (consultation, demo, etc.) 👉 Saves time and reduces manual coordination. 4. Good integrations Google Calendar / Outlook sync Video tools (Zoom etc.) Helps keep everything centralized 5. Open-source flexibility Built on top of Cal.com Can self-host or customize if you're a developer 👉 This is very important for you if you're planning a scalable platform. Cons Limited customization (big one) Booking page design options are restricted Branding flexibility is not deep Advanced workflows need workarounds 👉 If you're building a marketplace like UrbanClap, this is a limitation. 2. Learning curve for advanced setups Simple use = easy Complex workflows = confusing Needs better onboarding/docs 3. Integration limitations Not as rich ecosystem as tools like Calendly Some users report missing external integrations 4. Occasional sync/reliability issues Calendar sync glitches reported Requires manual checking sometimes 5. Mobile & advanced features still maturing Some features feel incomplete Custom automation and edge cases not fully supported Review Source Response from OneHash April 24, 2026 Thanks, Suresh. Happy Cal ID is delivering value for quick setups and automation. Your feedback on flexibility and integrations is noted. Ranganathan M. Director Construction Used the software for: Less than 6 months ### "Best Scheduling App" January 20, 2026 5.0 Minimalist Design: The interface is very "quiet." There are no aggressive ads or complex dashboards, making it easy for both you and the person booking the meeting. Speed: It is incredibly lightweight. The pages load quickly, which reduces the friction for someone trying to grab a slot on your calendar. Privacy-First: Unlike some larger platforms, Cal.id emphasizes data privacy and doesn't track users as aggressively. Customization: You can create "Secret Events" that don't appear on your main booking page, which is great for specific high-priority clients. Pros Cal.id is built for people who find mainstream scheduling tools too cluttered or corporate. It allows you to sync your calendar, set your availability, and share a link so others can book time with you without the back-and-forth emails. Cons I dont think any major issues like any other scheduling apps. It has lot of lfexibility that can benefit the users Review Source Response from OneHash January 29, 2026 Thank you, Ranganathan. It’s fantastic to hear Cal ID’s clean design, speed, and privacy focus are hitting the mark, and your appreciation for features like “Secret Events” truly motivates us to keep innovating. Akshat S. Founder Pharmaceuticals Used the software for: I used a free trial ### "Very useful app" December 6, 2025 5.0 Overall, Cal ID is a robust scheduling tool that offers impressive flexibility for its price point. While the user interface is generally clean, it did take me a little while to fully understand the advanced workflow settings compared to simpler tools I’ve used in the past. However, once configured, the system works reliably. The customizable booking pages and routing forms are standout features that have helped me manage a complex schedule with ease Pros Appointment management, email notification ,booking and every feature is good and worthy of price .great Cons I have noticed that the calendar synchronization can sometimes be sluggish. There is occasionally a delay between updating my availability and seeing it reflected on the booking page, which makes me nervous about potential double-bookings during my busiest scheduling periods Review Source Response from OneHash December 22, 2025 Thanks for sharing your experience, Akshat. We’re happy Cal ID’s customizable booking pages are adding value, and we’re actively working to resolve the calendar synchronization issues you mentioned. Rahul H. Chief Dentist Hospital & Health Care Used the software for: Less than 6 months ### "User friendly booking system" February 9, 2026 5.0 We can absolutely eliminate use of pen and paper to register an appointment. A link can be shared to new patients, where they will be able to see all the available appointments and book easily according to their convenience. While using pen and paper, we need to glance through to see the available timings, but using cal id eliminates that as it displays only the available slots to the patients. Pros It is very simple interface, anyone who has no idea about booking system can manage to use it. It provides seamless and easy way to book appointments for my dental patients. Cons Quite a few like custom messages are not available. If we have to send custom messages, whatsapp business has to linked to the cal id. Review Source Response from OneHash February 25, 2026 Thank you, Dr. Rahul happy to hear Cal ID makes patient booking easy, and we appreciate your feedback on custom messaging. VG Vrinda G. Founder Mental Health Care Used the software for: 6-12 months ### "Amazing software" April 30, 2026 5.0 Pros I have been using Cal ID for over a year now, and it has genuinely been a game-changer. Their customer service is amazing. Any time I have had an issue, it has been resolved instantly. Because of my busy schedule, automation is a must, and with Cal ID, it has worked seamlessly. Cons Lack of their own payment system. Razorpay and Paypal charge comissions, so if Cal ID could integarte their own payment system, that would make it much easier. Review Source Response from OneHash May 6, 2026 Thanks for sharing, Vrinda great to hear it’s been seamless; your input on payments is noted. Haris I. CEO Accounting Used the software for: I used a free trial ### "It significantly improves operational efficiency and customer experience."

Pros Cal ID provides a clean and intuitive interface that makes scheduling and booking very easy. The platform is reliable and efficient for managing appointments, with smooth workflows and minimal friction. It helps streamline operations and saves time, especially for teams handling multiple bookings. The overall performance and usability are impressive.
