Sprint.AI vs Explosive Sprint Timer

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.
