Comments on aCalendar+ Calendar & Tasks for Android
★★★★★Nelson Ferreira· Jul 27, 2025
Best Android calendar, and I have been using it for probably more than ten years now. What I most like about it is the week view, which not so common in competitors. Navigation is pretty straightforward.
★★★★★Mary Jo Engleton· Jun 22, 2025
I have been using calendar+ for well over 10 years. I love this app. I find it very intuitive and easy to use. Over the years I've tried other calendar apps and always come back to calendar+!
★☆☆☆☆Adi Pratomo· Sep 4, 2025
Tried in free mode to check if I can add corporate email account to it. It said I have to purchase the premium version (calendar+) I purchased the premium one, and it does not support corporate email account. Try to refund but it was declined. Felt like being scammed.
★☆☆☆☆eric fehrman· Sep 8, 2025
I have loved this app for years, but after the last update everyday I have to reset what calendars are shown... otherwise my calendar is blank. If I forget to do this everyday (sometimes multiple times per day) then I will miss alarms and appointments.
★★☆☆☆Brian Gilman· Jul 19, 2025
All of a sudden events are dropping off my calendar Plus but are still on my Google calendar. Having sync issues.
★★☆☆☆Janie C· Sep 16, 2025
I bought this many years ago and have loved it until recently when I've begun having trouble editing all but the bottom event of the day. Very frustrating! The symbols (pencil, etc.) won't come up at the bottom of an event for me to edit. I have to go to a native calendar app to edit.
