Ratings and reviews

Update 3/29/25 Doesn't sync new events on my Samsung S24, even when I manually sync, but syncing still works on my S22. I have to wait for some unknown something to get it to sync. As you can imagine, this renders it useless. Love the birthday photos, the calendar color choices (I have 6 different calendars on my device and it handles that beautifully).

Excellent user interface and plenty of options. I would give it 5 stars, but it has a MASSIVE flaw: notifications stopped working a couple of months ago. The built-in test works and I've tried all of the suggestions regarding power settings, etc. The developer says it's a Samsung problem. Notifications work for every app on my phone except aCalendar. It's not a Samsung issue. EDIT: Yes, Samsung and Google calendars both work.

I have used a calendar for years and find it to be easy to use with many customization options. It seems that I used to be able to set alarms for my appointments, rather than notifications. I haven't found a way to set a ringtone for a calendar notification, and the short tone that is used now does not catch my attention. Hoping that this is changed so I don't have to find another calendar app. Thanks for the good work!
