Missed the point – Free Reaction Timer for iPhone Review

Lights do not work correctly. No pre-stage and stage lights or yellows. Just red to green. Also it say reaction time of .399 or less is good. A perfect reaction time off a tree start is .500 seconds. And it's almost impossible to see which light is on. Could be really good with some changes.
