Ratings and reviews

*update Oct 13, 2025 - I suddenly keep getting notifications for birthdays a week early, even though I have that setting off and only should be getting the notification day of. I messed up and didn't realize the date wasn't correct and wished someone happy birthday early. Not sure why it started doing that randomly. Please fix! Took a star off until fixed.* I've been using this app for many years and absolutely love it! Amazing app with great features!

I have a Galaxy S24+. aCalendar is my go-to android calendaring app. It has more features than the Google desktop calendar and is laid out in a much more logical manner. I would give Calendar five stars, except I cannot figure out how to view, add, update, and delete calendar tasks. I cannot find such a switch in aCalendar. This app is named "aCalendar+ Calendar & Tasks", yet I cannot find a way to switch into task mode. If that can be pointed out to me I'll change my rating to 5 start.

This was my most favorite calendar. I love the day widget and live by it. It will not sync. I have contacted the developer and they say it's a syncing issue with Google, but when install similar apps that are interfacing with my Google calendar, immediate changes are seen between apps. My issue claims to be network, but I've tried being on WiFi and cellular and neither fix my situation. This just started about a month ago and uninstalling, reinstalling etc has not fixed the problem.
