Playstore comment by Karl H.
Should not turn the screen off if the screen was on to start with (re-read Julian C's review carefully). Also, the setting about whether the phone is locked should instead be based on whether the screen is off. Phones can be unlocked but have the screen off... Also there really needs to be a "Don't keep any history" option. I don't want this app to store battery history (tip: neither does anyone else; there are other apps for that). I can't see how to access the history anyway.
