Ratings and reviews

App works but one issue I can't seem to get my head around, I use DAVx and my actual calender entries from subscriptions are listed twice. Removed and added the subscriptions back, same result

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.

Does exactly what it was designed to. The only minor issue is that it raises a notification immediately after failing to sync due lack of internet. Ideally it should wait for the connection and then sync silently. Only warn the use if the connection failed with Internet on.
