After installing the alarm emerged in parallel to the existing standard alarm by clicking on the clock. He has exactly the same functions (alarm clock, stopwatch, timer) and up to small details, which are well hidden in the settings, unfortunately, no recognizable meaningful additional functions. Added to this, the permissions that are not explained (I have nothing against necessary permissions, but then would like to know what are really needed) In my opinion, an alarm clock does not need to know the wireless status, nor read my identity. In addition, among other permissions: "Change System Settings"
