Google Play is very bad for providing support. So if you have any issue with the app, need help with it, or have some good or constructive to say please drop me a note :) 

If you're having problems keeping Notification Booster running, check you phone here for additional instructions: https://dontkillmyapp.com

In newer versions of Android, the phone limits notifications and interruptions during some activities, for example when you're on a call, notification sounds are silenced. This caused me to miss important meetings as the my mobile phone did not alert me when I was in a call.

So I created the Notification Booster app. 

I actually use it only for calendar notification, but I think you'll find it useful if you need additional feedback from your phone because you miss notifications. So if you work in a noisy environment (such as a factory or production line), or if you have some hearing loss, or if the system notifications just does grip your attention - then I think you'll find this app useful. I hope you'll like it!
