User reviews
Users find 'Checker Plus for Google Calendar™' very helpful and reliable for event reminders, praising its snooze feature and the responsive developer. However, multiple reviews mention bugs with auto-adding events, syncing challenges specifically on Edge, and occasional login issues. Some users request UI and translation improvements alongside better notification updating. Overall, it is highly regarded for its functionality and customization, albeit with some reproducible bugs affecting syncing and event creation.
Pros
- Very helpful and useful for managing Google Calendar events and reminders.
- Developer is responsive and actively maintains the extension with new features.
- Includes a convenient snooze feature for reminders.
- Allows easy access to calendar notifications and mouseover event previews.
- Customizable with lots of settings and configurations.
Cons
- Auto add event feature is buggy, sometimes creating multiple duplicates and placing events on wrong dates.
- Sync issues on Edge: Events created in the extension sync to Google Calendar, but Google Calendar changes do not sync back reliably to the extension.
- Troubles logging in on Edge, similar issues as seen in Chrome.
- Periodic need to open the app to update the agenda and generate desktop notifications.
- Translation and UI improvements needed for languages like Portuguese and for contrast in dark themes.

This is such a great and helpful app! Sadly, our org just switched over to M365 and Outlook :( Is there such an add-on/extension for Outlook Calendar?
