Calendar Event Reminder (CER)

    DOWNLOAD  $2.79



    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.

    Beware. Calendar Event Reminder took over my phone. I can not longer do anything on it.

    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.

    When I think I paid for this! It is so annoying. You can't specify exactly when you want it to ring. It does with each Calendar reminder. That is no good. I want many reminders but only one alarm. It is also difficult to use /understand. Waisted my money. Nexus 6P Android 7.1.1.

    The only thing I would change is to have more snooze options. There are only 6 buttons and there should be at least 9 and preferably 12 or more. It would also be nice to see those buttons retain their order position when the orientation of the phone is changed from portrait to landscape.
