About this app

THE App for calendar reminders - never forget an appointment anymore! Perfect for business user!
Calendar Event Reminder (CER) adds a repeating calendar reminder and extends the stock calendar application. You can customize the duration, repetitions, sound and vibration pattern. Works with every synced calendar.

After adjusting CER's settings to your liking, add a calendar reminder to your existing calendar to see how it works! When alarm / reminder goes off the device will be turned on and a popup window with information about the event (title, time, location) is displayed. Alarm / reminder can be disabled by tapping Dismiss or snoozed by the Snooze button.

I had really enjoyed using this application. It had worked as promised, but that has changed. The pop up event reminder no longer works. I've sent two messages and it's been over a week, but I've not gotten a response. Please fix this so I don't have to uninstall this application. thanks UPDATE,,,The reminder is working again. Thanks update...the holidays are now off by 1 day. Christmas day 2018 is shown on Dec 24. Really like app but need help with this. Jan 18 update...still waiting for help.

Alarms at or close to 12pm do not go off if theyre set a few hours before 12pm. The rest of the alarms do go off.Also if i go in the app and make an alarm go off to snooze it before it goes off on its own,if an alarm is due at that time? It never goes off nor is listed in the notifications. This app has alarms organized by day. Its the best one other than that. Im on android 8. Please if you can, fix the alarm not going off issues.

The app suffers from neglect now. It consistently reminds me of all-day events (like birthdays & anniversaries) on the wrong day. Usually the day before, but slightly less than half the time, it's the day after. I assume that's a compatibility issue with current Android, and I will come back if fixed. Until then, I'll be uninstalling and searching for an alternative. Thank you for many years of service.
