Twisty Timer is a material design twisty puzzle timer for Android. It uses the TNoodle library to generate scramble sequences for all current official speedsolving puzzles.
Not often but sometimes it can happen that you come over the inspection time (so automatically you get a +2, excellent feature) and at the end the puzzle is rotated in one layer. So according to WCA rules you would get +2 and +2 = +4. This is not possible.
Theoretically I think you could get also a third +2 for not starting the timer with flat hands and also a fourth +2 for not stopping the timer with flat hands but I think this not relevant if you us a smartphone timer. It is not a competition!
