Been using it for years & syncing it with Google shared calendar with family. However, recently there was syncing issue thus decided to uninstall. Sad.

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.

Out of all the multi calendars out there this is my absolute favorite. Simple to use, and I love the weekly View of 7 simple squares. It also easily sinks with Google Calendar, which I really don't like. Five stars all the way!!!

Earlier events all missing. Can only see tasks from Mar 2025. And some completed tasks from June to July 2026 suddenly went missing. I discover that under Settings, Accounts, Google, calendar auto-sync cannot be turned on.

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.

Great calendar UPDATE: they made this app unusable. First, banner ads that popped up suddenly to trick you into clicking them were annoying. But now they force full screen ads with no x to close out and lock out your phone's navigation buttons forcing you to watch a stupid full screen ad for a minute before you can close the app. Completely unacceptable. I deleted the app and switched.
