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.

    This app used to work great on my Droid 4. On my Droid Mini it's completely unreliable. I click on a notification of one reminder and a COMPLETELY DIFFERENT reminder comes up. I have dismissed certain reminders and it goes in to my bank of reminders and dismisses a different reminder. I have missed important tasks and meetings because of it. Additionally the constant pop-ups are extremely annoy

    Please bring back the previous version. The new one is overly complicated and it is not possible to view a whole day on the 5 day plan, without scrolling down.

    I really love this app which works very well for me, and have recommended it to others. It's installed on my Samsung Galaxy S5, and I previously used it with success on the S2. However this morning I installed the update, since when I am unable to open the number pad when using the "custom" snooze time. That means I am obliged to use the built in number scrolling which is a more lengthy process

    I enter my crazy work schedule on my phone's calendar app and this app turns it into my alarm clock automagically. LOVE THIS. I wish I could cancel an alarm from going off from within this app if I arose beforehand though. I have to go through all the steps to remove it from the calendar (twice due to repeating/sync probs) THEN cancel through this app.

    I usually forget everything and a simple default calendar beep is not enough to remind me of events. With this app I can customize my events with loud sounds etc so I won't forget my events. Keep on your good work... :o)
