It does affect the battery life. Uses 8% of battery. Even without proximity sensor turned on. So have turned off.

Let it run for a day and then check the apps battery consumption. It should be minimal (as opposed to other "Shake to do something" apps available on Google Play).On the PRO version:1 - you can set 3 different actions to be fired, one for every axis of movement, instead of the single one available on the FREE app.2 - no ads are displayed.3 - the user can choose to start the app automatically after the device is turned on.4 - the app can be set to unlock the screen automatically when the screen is turned back on.5 - the app can use the proximity sensor to avoid accidentally firing actions when the device is on a pocket, for instance.6 - The device can be set to vibrate every time an action is fired.UNINSTALLATIONDue to the fact that the app needs admin privileges to run, if you want to uninstall it you must do it by clicking on the uninstall button inside the app.COMPATIBILITYUnfortunately, on some devices the app will not be able to fire actions when the user shakes the phone after the screen is turned off. Its a hardware limitation of these devices, and there is nothing that can be done on the software side to avoid it. For instance, Ive tested the app on the LG Nexus 4 and it works flawlessly; on the other hand, on the Samsung Galaxy Ace the accelerometer sensors are turned off the moment the screen goes off. If that is the case on your device, please send me an email (there is a button on the app to do it) explaining what is happening on your specific case.PERMISSIONSPrevent phone from sleeping - necessary to wake the phone up after its screen is turned off.Vibration - necessary in case the user wants the phone to vibrate when the screen is turned on or off.Run at Startup - necessary if the user wants the app to start automatically after the device is turned on.Disable Keyguard - necessary if the user wants the app to unlock the device automatically when the screen is turned on.Modify Audio Settings - necessary if the user wants to set the device to Silent or Vibrate ModeCamera - Necessary to turn the Flashlight on and off.Device Admin - This app uses the Device Administrator permission.

Reviews
This is a good app in general. It does the job it was designed for. I installed it because I wanted a way to put my phone on mute once shaked. I uninstalled it because the app reset the volume levels to different volume settings once it's shaked again to unmute. Not convenient.
Seems to be working perfectly; hope it keeps it up.
