Just downloaded and tried out a new app - Speedcube Timer (android, free app).
Tap and hold to inspect, release to start and tap screen to stop. Very responsive.
Scoreboard - Lifetime average, best, average of 5, average of 10
Solve history - Date, time and solve time
Puzzle type - 2x2 - 7x7, megaminx, square-1 and pyraminx.
Export history to SD
Clear records, and a variety of options I don't fully comprehend.
Only thing I think is missing (and I will give it an extra point if I someone shows me where the feature is) is tap, timed inspection, start (like in the comps, or on cubetimer.com), rather than tap hold to inspect release to start.
I rate it 9/10
Any other timer apps (android, iPhone, symbian, or Windows etc) people can add to this kitty?
