OCT 2022 (5 stars) I spent a lot of time looking at all the calendar apps, and in my humble opinion, this is the best calendar app. UPDATE: Dec 2025 (2 stars) The ads are unreal, even though I paid. They come on full screen and they won't go away for a full 20 to 30 seconds. With one ad, I had to restart my phone because the ad wouldn't go off... going to get another app. This one now is terrible. I understand that nothing is free, but this ad is now abuse.
