Pay attention to how much you pick up your phone to check for notifications. Now imagine never needing to do that again. That's why you should install Vibration Notifier. Your phone will keep vibrating at intervals you set until you pick up your phone. It's extremely useful in noisy situations where your phone is unlikely to be heard. It eases the anxiety of potentially having a missed text or IM sitting on your phone. It's a simple app that greatly improves the user experience.
Maybe you know this situation: Your phones lays on your desk, you're in the kitchen and you get called. You do not hear your ring and when you come back to your desk, you don't notice that you were called because your device has no notification LED or you don't notice that little blinking... Vibration Notifier offers a solution to this scenario: When you have a missed call, unread SMS or any other event*, the app keeps vibrating every X minutes for Y times or until you turn on the display of your device.
Troubleshooting: The app won't beep if your device is set to silent mode etc. Please note that the app does not change the vibration setting of the other apps, it will only do additional vibrations/beeps if you don't turn on your display before!
An optional feature is available as an in-app purchase (0.99 EUR) with which you'll get these repeating vibrations on your Android Wear smartwatch!
* all apps which notify you about new events by showing a notification in the Android status bar are supported, like WhatsApp, GoogleTalk, Twitter, facebook, etc. Note that this require access to your notification bar
Silent hours: Please note that when you set up a silent hours interval in the app, only Vibration Notifier itself won't vibrate or beep. It does not mute other apps so if you receive a new mail, your Gmail app might still beep!
