I like this app, but it would be nice if there were a feature that allows you to check off tasks/events as completed. Also, when the app notifies me of anything, it is linked to my Google calendar and both go off at the same time. This is redundant and came as a surprise to me, since I figured what I put in the A Calendar app would be in addition to what I have in Google calendar, not added TO my Google calendar. If there's a way to fix this issue, I'll add a star ⭐ to my review :)

Tasks and events are separate from technical and UI perspective, but both can be marked done. Usually, in Android, all calendar apps are user interfaces to all your calendar data (local and cloud) stored centrally in Android. If you don't want notifications from the Google calendar app, you can turn them off there. For more help use MENU - HELP.

I haven't found an easier front end to g-calendar, but I stopped looking after a couple of weeks of using aCalendar. I've seen comments about pop-up ads, but if there are any they haven't been annoying enough to impede my progress. You can pay a bit to stop ads and add some more features, and I've been tempted, but I don't know that I'd use them. On the other hand it would help the developers, and I'm all for that with apps I use. Aw, what the heck, my next move is going to be an upgrade.

Excellent product and support I've been using this for about a month and love it. I particularly like the hybrid view widget that gives me a view of both my calendar and tasks (optional add on but very inexpensive) for the day in one place. Tech sure has been very responsive, which is rare.
