SprintStart for Sprint Block Performance is the leading tool for your sprint and race start training. Using our sprinting start optimized app, your iPhone and Apple Watch can call the starting sequence and start your race. Record, sync, and share your start training sessions.
WIth our reaction time measurement, your response to the starting sound helps you track your performance out of the blocks and off the line. Using your device's acceleration sensors, your reaction time is recorded and displayed, and synchronized via iCloud to all your devices using SprintStart.
Trigger a start from the app, from Siri, a shortcut, and your Apple Watch Ultra's Action button.
