Train sprint reaction anywhere

Only for iPhone

Sprint Start helps athletes train reaction time and block starts without needing a partner. When you train alone, it’s impossible to create a truly random start — you always anticipate the “go” in your head. That anticipation doesn’t exist in a race. Sprint Start fixes that. By delivering unpredictable start cues with adjustable timing, Sprint Start allows you to practice your reaction and block starts in a way that actually translates to competition.
