Very easy to use!
Now with new Volume Control function!
Use the app as an alarm for power surge when your battery is really low and you depend on your wake-up call. Works even better with the new Volume control.
Open the app - Start charging (or use the Motion Sensor function) - Lock your phone (optional) - Done!
To stop alarm - Open your phone - Double click on Home Button - or swipe up from the bottom of the screen and pause slightly in the middle of the screen.
Then swipe up on the app's preview to close the app.
The new Motion Sensor has an about 5 second delay so you have time to put it away. The sensor is very sensitive.
Perfect to use at the airport, your office, library, or in any place where you will leave your device unattended for a short while.
Also if you get a power failure, or if your power pack loses all the power, the alarm will go off.
When using for example an Apple Smart Power Case, you have to use the Motion Function as an alarm since the normal function senses power loss.
Works on wireless chargers as well.
