I love this app. It works absolutely. No way i could transfer all those calendar data from my phone to another app without this helpful app. No fuss.

Works like a charm! I needed a way to connect my MS Teams invites into Google. Tried many options, this one worked. And then the support I got.. mind-blowing!

It took me 2 seconds to delete the local calendar created by scam website with thousands of events every hour for 4 months. Thank you so much. Helped a lot. Rating 5 star by heart 💓.

Thank you for solving my Google Calendar spam issue. No antivirus or malware removal apps could even find the problem. Thanks again for solving my problem. I feel so relieved. You guys rock!

This app did what the Samsung, google, and android xfer apps couldn't do! Move my phone-only Samsung calendar entries to my new pixel phone. What a relief! Thank u very much for this app.

I needed to export from the phone's private calendar to something that would synch across all my devices. This worked perfectly!

Way too complicated. Spent half an hour trying to figure it out. Just wanted a simple app to sync my Google Calendar, Outlook calendar and Samsung calendar. This is definitely not that app... uninstalled.

I used this app to remove 1400 spam fake virus event reminders from "my phone" local calendar. What a life saver! Only concern is it appears to be quite a power tool so be careful on the calendar you select to clean. Highly recommend

Since I've been getting random (YOUR ANDROID IS ON RISK!) thing on my calendar I've been trying to delete the account where it was spamming the (YOUR ANDROID IS ON RISK!) But I can't becuase of this random local account so I saw google support saying download this app can delete local account. And it helped, thanks to the creator who created this app.

I have 2 university degrees and a college diploma, and I still have no idea how to use this app. NOT intuitive at all. **Update** Thank you, developer, for getting back to me. It should not take an automatic call to "customer service" just to install and use your app right from the get-go. Take the hint: Better UX Design. Thanks for reaching out. - JF

So far, So good. I gave this a try after DAVX unexplicably stopped syncing my NextCloud calendars. Yes, the interface is as ugly as sin. But, so what. At least it shows you what's going on [unlike DAVX, which just spins a sync cursor but doesn't sync]. CalendarSync worked where DAVX doesn't any more. Holding off on a couple of stars coz I don't want to give it file access [I don't get or use calendar attachments] and it won't stop bugging me about this "required permission".

I'm sorry but this is way to confusing. It seems I haven't set up my accesses correctly but there doesn't to be a way to repeat that section. Also the UI is too 'unusual'. You seem to end with an email the developer option all the time.

Worked perfectly to export a calender from my phone, I was able to share the file to my email and WhatsApp and later simply imported the calendar do my Google calendar. The whole process took 2 minutes. No issues at all, super useful. Thank you

I was looking for a way to sync some CalDAV/WebDAV calendars that GCal just couldn't get right. CalendarSync solved the problem. I agree with other reviewers that the UI is initially confusing; my first attempt to use the app failed. On request, the app will create an email and attach your config so you can get help from the developer. I took advantage of this and I now have a working configuration. And for a few dollars I can support a developer who has created an app that works and is not only responsive, but continues to follow through on questions.

This app worked for me to sync my phone with my yahoo calendar. All other apps I tried in late 2019 failed because of yahoo changes earlier in the year. It did need some tweaking to make it work, but the customer service from CalendarSync was phenomenal - probably the best I've ever received. Thank you!

Did what I needed and exported my Samsung Calendar to .iCal. Idk if it was Google or this app but once I imported over 350 calendar events to Google, many events had an extra day added to them, some Reminders that were spread across a given month were grouped all to the same day instead, and emojis in event titles do not transfer. I'm just happy I finally found an app that exports SCalendar and doesn't siphon data in the background. Permission requests should be on-demand instead of all at boot.

After reviewing the answer of the devs, I gave it another try. The UI is a complete mess - that's why it was not really obvious, how to really activate the automatic sync and the interval. Now the app does exactly what I want it to. It would be a five star app with a nicer UI. I think, I am going to buy the full version now. Thanks for the kind reply.

Excellent! Works very well, does what's intended to. 4 stars because maybe it could offer an easier UI/UX. Nevertheless, the task of syncing / migrating / transferring a calendar is a bit of a complex one in and of itself and this app delivers. I used it to migrate my Samsung calendar to Google. It did have a small problem on repetitive events with rule exceptions for some of them, but I didn't really mind. (The app has options to deal with these and many others I just didn't try them.)

only app that worked. "calendar backup" created a buggy .ics file, this didn't. used to backup local Samsung calendar approx. 3mb. and export it to new phone. app interface could use an update.

THANK YOU to the developer of this app!!! I found a recommendation for this app buried deep in a calendar help blog from 2022 and it's the only thing that worked! 803 calendar events that I did NOT want to enter into my Google calendar one at a time after updating my phone!! I can't believe in April of 2025, a Samsung 25 doesn't have the ability to easily copy the "My Calendar" (local to phone) automatically. This app saved me!!! Thank you!!
