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.)

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.

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.

To repeat that section simply execute the same configuration steps again, then (at the beginning) you will be able to select again how your appointments can be accessed. If you are unsure about the configuration I recommend to check out the provided email option. Simply send a mail to calendarsync@gmx.at with some details and I can help you.
