A fast way to launch or close your favorite App on Android!
Shake to Launch Your App.
Shake again to Close It.
To avoid accidental launch of the App this service works only with Phone Screen On.
There is also another battery saving feature - Screen Off to close the App. Closing the app keeps Phone battery working longer as the App is no longer in the memory after its use.
You can also manually disable persistent notification, as it is initially is visible due to Android requirements.
In Oreo and Huawei: please disable battery optimization for this app. Also make manual battery launch control. To avoid it killed when phone is sleeping.
NB. Don't forget to select your App in settings first!
