Description of Calendar Event Reminder (CER)

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.

NO LONGER IN DEVELOPMENT for 2 years! I really wish I hadn\'t missed that! Google has to keep mucking with reminders causing havoc for third parties. Yet their calendar app doesn\'t offer BASIC snooze functionality from Palm OS from 2002! Just viewing event cancels the alert, HOW AWFUL! I\'m trying to replace Calendar Snooze which just went out of development as well. This app is okay, but I never want a popup over screen. You can\'t sent the vibration pattern separately from the alert time. It has a constant notification that CER is running which is awful. A 2 hour refund limit on top of that is NOT enough time to test an application like this! Google needs to stop allowing sales of applications that are no longer in development without a clear warning AND better return policy. So much for not being evil.

Got CER hoping to compensate for the new, degraded 2019 Google Calendar - (It\'s bloated up with tons of new features, but, unfortunately they decided to do away with the ONE thing a calendar is supposed to do - effectively let you know when an event is coming). CER only worked intermittently and even then it was several minutes innacurate. Is it all that hard to just make a calendar app that makes repeating notification sounds of your choice at specified times until you shut it off?

I bought this and used it for years. It was a literal life saver. I depended on this to provide repeat notifications until acknowledged. It was and still is the most configurable application that does this. The best of the best. However it doesn\'t work with newer Android OS\'s like that of my galaxy s9. It\'s a shame. Now I must buy an inferior application to replace it with.

Updated again, new update just made issues worse. I just lost all ongoing reminders AGAIN. Happens at least weekly, no idea why. Lots of reminders never fire or are late, but no patterns to explain why. Amazing for a long time to keep me on track, but it\'s been buggy since Android 5. Now with Android 6 and 7, they may not fire at all, may fire late, one or all may just disappear. So disappointing because it saved my job. I\'ve given numerous chances, but have to uninstall and find something else

The most useful app in my arsenal. At it\'s core, it makes a loud alarm ring when there is a Google Calendar notification so I don\'t miss alarms. It works out of the box and it has a gazillion options so I can make it work the way I want it to. Well designed interface, especially considering how many options it has. This app works hard for me. I\'ve have it since 2013 and it is invaluable on a daily basis. I\'m using a Moto X first generation phone.

Doesn\'t work Newest version of Android doesn\'t seem to allow permissions for this app to function properly. Alarms will not work!
Bryan McKenna 2016-03-15

Still the same issues - app has been abandoned, randomly stops firing alarm notifications. Would be one of the best productivity apps I\'ve seen if it worked consistently.

Abandoned app. Perfect app when bought in 2015, but for a long time alarms fail to fire or fire late. All alarm/notif apps been updated to fix Android 6 Marshmallow \"Doze\" feature issues, not this one (last update Dec 2014!). No workarounds helped (devs site). TRIED: 1. Battery Optimisation, add cal + CER + related. 2. App power saving, set all to off. 3. CER \"Keep in memory\" option. OTHER APPS: 1. CER (different dev) has few features but works. No other apps allow songs + separate volume for cal notif.

Abandoned by it\'s creator. No longer works reliably. After purchasing this and using it for years I\'m forced to find an alternative. Abandonware.
Stacy Haight 2015-09-23

This used to be amazing I\'ve used this notification app for years. It hasn\'t worked the last two weeks. It doesn\'t notify me at all. I\'m sad because it really was amazing. I\'m not sure when it stopped working or why. Maybe my phone updated or something. I hope it gets fixed soon.
