Sprint Lightning
A GPS sprint timer in your pocket. Pick a distance, hear the gun, and run. A tone sounds the instant you reach your finish line, and your time is captured on the spot.
Free to start
Gun to finish line, no stopwatch
Start a session
Press Start Session and run however you like. Speed, cadence and distance update live the whole time.
Pick a distance, press Countdown
Choose 30, 40, 50, 60, 100, 200 or 400 m. After the countdown, the gun fires and the app starts tracking you.
Hear the finish tone
A tone sounds exactly at your target distance, and your time, top speed and cadence are saved with the session.
Inside the app
Everything a sprint session needs
Automatic sprint timing
Intervals from 30 m to 400 m are timed from the gun to the finish tone, so you don’t need a coach with a stopwatch.
Live speed and cadence
See your speed, steps per minute and distance as you run, plus your session max and a graph of the whole session.
Voice callouts
Hear it out loud each time you hit a new top speed or cadence. Constant mode reads your speed or cadence continuously.
Hands-free voice commands
Say “Countdown,” “Distance 200” or “Stop Session” and the app does it, with no fumbling with your phone between reps.
GPS you can trust
Filtering removes fake speed spikes. The diagnostics view shows satellites in use, update rate, fix accuracy and dual-band status on supported phones.
Full training history
Every session and sprint is saved with its stats and graph. Export all of it to CSV for your own analysis.

The video plays from YouTube and loads only when you press play.
