Ratings and reviews

It works at first but after awhile the sync stops and can't resolve the name. And the iCal events have changed but it doesn't reflect on calender in my Phone. 😭, Update - 11/2/21. Now my autosync is disabled with no reason. So I have to make manually update it. - Update 11/10/21 - I followed the instructions to make sure the app doesn't go to sleep but events that are on my calender will have been updated with new date and time won't reflect thru the app. Lost a star for it.

This is a great app that works very well for me. If it tries to run a scheduled sync when I don't have internet signal, it gives an error notification (a feature, not a bug), but when I'm back in signal I sync it manually and it works perfectly again.

This is working really well for me. There is one thing I would like to see added though. I like the option for setting a default alarm prior to each event, but to subscribe to some calendars that have wayyyy to many calendar events to want an alarm for each, but I do want to be notified of them. If there was an option for a silent popup that could easily be dismissed, and that would let me know something is coming up but didn't make all sorts of noise, that would be ideal.
