### "Very useful, does exactly what it says"

August 23, 2019

5.0

I sync my personal calendar to my work calendar, so it prevents people I work from scheduling time with me when I'm not available due to personal obligations. Before SyncThemCalendars, I would have to create an extra event in my work calendar for each personal event that happen to intersect with work hours. Now I don't have to think about it. Thanks STC!

Pros

\- Easy to set up - It does exactly what it says - Set and forget. I did it once and never had to mess with it again.

Cons

I wish there was a way to distinguish between "organic" events, and events that were synced, so I'd know what comes from what calendar. But even without this, it's still god damn useful.

Thanks for your review, Michael. Just so you know, we do have a new feature that allows you to change the color of the synced events - that way you can distinguish between the organic and the synced events.

### "Where have you been all my life? "

March 3, 2020

4.0

Fantastic

Pros

We have several gmail accounts with different clients and booking meetings used to be a chore- I either had to update everything on each calendar separately (time wasting) or risk being double booked. This software automated that for me in a way that was better than IFTT and Zapier.

Cons

Really not a whole lot to it, but there are occasional bugs. Wish that there were a little more enterprise/business account management options.

Switched from

[Zapier](https://www.capterra.com/p/130182/Zapier/)

Zapier was clunky and tended to make duplicate events or only sync one way.

### "Excellent!"

November 16, 2022

4.0

Pros

SyncThemCalendars is a service that silently makes scheduling and managing my calendars easier every single day. After initial setup (see cons) it automatically copies events from one calendar to another like clockwork. This ensures that I never get 'double booked' into a meeting when I have something scheduled on different calendars.

Cons

The setup is clunky and a bit frustrating. Initially, during setup, I experienced a few errors that were hard to understand and required assistance from customer support. With support, we resolved the issues, and they haven't reappeared. The biggest con with this software is the price and functionality.I think it is expensive for basic syncing functionality - but I haven't found an alternative so I will continue to subscribe. Functionality is fairly limited, but the functionality it does have is incredibly reliable. Product development seems fairly slow, so I would not count on new features being added regularly.

Alternatives considered

[Calendly](https://www.capterra.com/p/148036/Calendly/)

Reason for choosing SyncThemCalendars

Calendly does not offer sufficient scheduling functionality with-in and organization. So syncthemcals offers critical communication of availability to my remote team.

### "Sync's my personal and work calendar exactly as I needed"

March 2, 2020

5.0

Pros

This software is simple, there is only a single dashboard page, but that is all that is needed. The software syncs between a number of different calendars with the only limitation being 5 syncs in one account. A two-way sync can be done if you set up a separate sync in both directions. It also makes it simple to decide which event fields to sync from each calendar and I use the colors so that it is quick to tell which calendar the synced even came from.

Cons

This software works great, insomuch as that I didn't need to make any changes to the configuration for a really long time. The downside to that was I could no longer remember the website URL where I needed to go to edit the settings.

Switched from

[Google Cloud](https://www.capterra.com/p/268690/Google-Cloud-Platform/)

I tried doing this sync using custom code in a Google Apps Script, but it was a lot of work and I still didn't have it working perfectly. I kept ending up with circular event replication or difficulty syncing deletions.

### "The Calendar Syncing App I've Always Wanted"

March 3, 2020

5.0

Easy to set up a dual sync, as I recall. I can add something to either of my calendars and feel confident it will appear on the other.

Pros

As a consultant (prior to my current role) I had a business calendar, a personal calendar, and often one or more calendars for clients. Now I'm down to 2 (personal and business), thankfully, but keeping the two calendars in sync is still a huge headache and can often trip me up. SyncThemCalendars fully erases this issue, making me a more productive and efficient professional.

Cons

Hmm. Nothing I didn't like. I mostly set it and forget it.

Alternatives considered

[Calendly](https://www.capterra.com/p/148036/Calendly/)

Reason for choosing SyncThemCalendars

Calendly doesn't \_quite\_ do this thing, IIRC. It will check multiple calendars for conflicts, but not keep two calendars synced.

### "Best calendar syncing tool ever--a must have for multiple accounts"

November 14, 2022

5.0

Love, love, love this product--consider it essential.

Pros

Easy to set up. Effortless syncing. Granular visibility controls. Just the best.

Cons

The only downside is the maximum limit of five calendars.

### "Managing Multiple Calendars"

November 17, 2022

5.0

It was easy to set up, and it keeps my calendars in sync.

Pros

I have multiple calendars (work, personal, client), and this tool brings all of those calendars into one view, quickly and easily.

Cons

Sometimes the system will miss a meeting cancelation, but really, I have no complaints.

Reason for choosing SyncThemCalendars

I didn't find any alternatives to do what STC does.

### "Simple Setup, basic utility that seems to do what it was created to do"

March 2, 2020

4.0

Overall, satisfied. But I don't spend much time confirming all is well. I'd certainly recommend if your use case justifies it. Reasonable price, easy setup and a utility cloud service that if needed it is great there is a solid paid option out there!

Pros

I use this for simply keeping thee of my team members personal and professional calendars in sync. Just a simple straight across 2-way sync. I appreciated the quick response and helpful spirit that the developer gave when I ran into a snag upon setup (a snag I created in a sense by not setting it up best the first time around).

Cons

I just noticed that one my my events are not syncing correctly today. I'll have to reach out to support and ask what happened to that one event of today. The rest seem to be fine. The event seemed to sync but the title of the event did not transfer correctly.

Pros

November 21, 2022

5.0

Pros

The ease of use to set up and sync two separate work calendars in order to avoid double booking.

Cons

The integration initially caused unexpected duplicate meetings, which required manually deleting each duplicate. That problem has not reoccured.

### "Does exactly what I need"

April 20, 2020

5.0

Pros

SyncThemCalendars is exactly what I was looking for. The fact that I can't easily sync my calendars natively was a bit upsetting to me, but I understand. This app did exactly what I wanted without having to write my own synchronization application, making it totally worth it's price.

Cons

Nothing in particular. The one thing I would like is access to an independent review of the software, or some form of audit that can be used to alleviate concerns by corporate users who may not be comfortable with this application having access to their internal calendars (for GSuite users).

5.0

Pros

I have multiple calendar accounts. I am constantly getting overbooked with people booking directly thinking I am available. Now that I can sync them, it makes my opening much clearer to my coworkers.

Cons

### "The Only Tool You Need for Calendar Sync"

November 14, 2022

5.0

I love this software!Now with my calendars synced scheduling is a breeze with the standard calendar scheduling tools. Before I had to manually copy events between calendars to keep from being double booked. Now it just happens automatically and I have no more meeting conflicts.

Pros

I am a member of several organizations that use different calendars. I searched it for years for a solution to sync my calendars. This is the only solution I have found that works and it beats all expectations. The sync is accurate and fast - usually within a few seconds.

Cons

If you have an excessive amount of calendars beyond the default number allowed costs can start to add up quickly, but the price is not unreasonable.

### "Exceptionally useful calendar sync software"

November 17, 2022

5.0

It's awesome and amazing value.

Pros

Not only can you sync calendars together, which is handy enough, but you can transform data at the same time. So you could show the title of the event, but not the location or the details, for instance, or you could just rename all appointments "Private Appointment". I use this for ensuring my team can access my personal calendar on my work calendar, but with only the details I want specified. I also use it for availability so tools like calendly.com work properly.

Cons

It doesn't always work 100%, but I'd say 99%. I use it for blocking off availability, so this isn't a big deal at all for me. I would also love more transformation abilities such as the ability to prefix something not just rename it. If it could work kind of like Zapier Formatting options, that would be awesome (maybe not that powerful!)

Reason for choosing SyncThemCalendars

No competing product exists that I'm aware of (short of ONE-directional syncs - this is BI-directional)

### "Only way to manage multiple calendars"

November 14, 2022

5.0

Pros

I got SyncThemCalendars (STC) when I was working at a fund and was managing projects (and emails / calendars) across multiple companies. STC is the best and only option I've found for getting all necessary info on one calendar, to be used with something like Calendly so you can make sure you're not overbooking between projects.I'd highly recommend to consultants, fund managers, or people managing side projects in addition to their core work.

Cons

There is nothing I don't like about SyncThemCalendars. It just works, so I don't have to think about it. Magic.

November 15, 2022

4.0

Overall it's good and I'm happy.

Pros

The syncing is flawless and gives me good control over how I want events to show up across multiple calendars.

Cons

It's limited to only Google-based calendars. It'd be so lovely to sync one-way-sync iCal feeds and multi-way sync to Office 365. This has limited it's usefulness to friends or colleagues.Also, I wish the syncing rules were just easier to do bi-directional sync as a single step.
