Comments on aCalendar - your calendar for Android

★★★★★ Steve W. Lai · Feb 24, 2026

Support vertical scoring, clean interface, horizontal scoring for weekly and daily view. Support Google Calendar, and local calendar. That's all I need. 👍👍👍

★★★★★ ABJ photography & video · Sep 21, 2025

Found it, settings - view settings - start view, thanks 👍👍. It's good, but would be better if you can set agenda as default view. Settings - calendar settings : no option to set default view. Settings - view settings : no option to set default view. Playstore version 2.9.5

★★★★★ Lior Renous · May 22, 2026

Best cal app interface in terms of views - I've had it for years, and the sync hasn't faulted. (I have many Outlook and Gmail calendars—I wish there was a desktop equivalent.)

★★★★★ Lex Strickland · May 24, 2026

I look around from time to time and calendar still has the most logical, easiest to view Week View other apps should have. I've used calendar for years for this excellent feature. Also love how it seems to memorize appointments I have to set regularly, so I can quickly enter those events. Event name and times are there for a tap.

★☆☆☆☆ Kimo Clyde · Sep 5, 2025

I am now getting scam entries about purchases through this app as calendar events. I have never had this before using this app. Why now?

★☆☆☆☆ Jennifer Torres · Aug 27, 2025

IT'S BEEN DELETING ALL MY VERY *IMPORTANT* CALENDAR DATES?!?! I KEEP TRACK OF ALL KINDS OF IMPORTANT DATES & THINGS THAT HAPPEN ((AS THEY HAPPEN?!?)) SO WHEN I GO BACK TO CHECK CERTAIN DATES & THEY'RE ALL GONE?!?!!! LITERALLY, ALL BLANK?!?!! THAT IS NOT OK!!!!! I'VE HAD THIS APP FOR AGES & CAN NOT BELIEVE IT IS NO LONGER RELIABLE?!!! WHEN I INPUT IMPORTANT DATES & THINGS INTO MY CALENDAR, I WANT & NEED THEM TO STAY THERE?!?!! PERMANENTLY?!?!! ISN'T THAT THE #1PURPOSE OF A Calendar?!?! HELLO????!

★★☆☆☆ fil wetfoot001 · Apr 1, 2026

Beside regular prompts to upgrade to the paid version of this app, I am now receiving spoof events in my calendar claiming I owe 'web shield services' several hundred dollars. I like the layout of this calendar but will be deleting it due to questionable integrity. Quick response from developer explains this is spam from my email, but there is no evidence of such emails being received by my email accounts. The spoof events have not been added to Google or Samsung calendars.

Used to be great, have had it for many years now, but since a few months, I can't trust the alarms anymore, they either don't pop in, or randomly AFTER my meetings!
