Sprint.AI vs Sprint Lightning

Sprint.AI allows users to accurately self-time their sprints, without the presence of a coach or the use of a external timer. Powered by our neural network, trained on over 100,000 data points, the timer will automatically start and stop whenever it detects that you have started/ended your sprint! Beyond timing, our sprint-form analysis model provides in-depth data on your sprint form, including body angles and joint annotations. Using the power of Sprint.AI, drop your PR's and boost your fitness! NOTE: While the self-timing feature works well when holding your device in your hand, it is recommended to use a phone arm sleeve.

Precision Track & Field Timing. 10Hz Dual-Band GNSS for Elite Sprint Analytics. Sprint Lightning: Instrument-Grade Performance for Elite Sprinters Stop relying on generic fitness trackers. Sprint Lightning is a high-precision digital coach designed specifically for track athletes, sports specialists, and elite sprinters who demand absolute data integrity.

Sprint Lightning solves this with our proprietary Iron Lock™ Spike Protection and L5 Dual-Band GNSS integration, providing accuracy previously only available in expensive $500 external hardware.
