What’s New Version 1.5.1
Bug fixes and other improvements.
Description
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.
