The data fixed my form

My coach kept telling me my butterfly stroke rate was too high and inefficient, but it was hard to grasp without the numbers. Seeing my DPS at just 1.2m was a real eye-opener. Now I’m focused on stretching it to 1.5m

The heatmap keeps me honest

Watching those green squares fill up is so satisfying, and the empty days stand out like a sore thumb. The app doesn't nag you at all, but it works better than any alarm clock

Posting a card to my stories after every swim has become my new routine. I constantly get asked what app I'm using. That pixel-art style is just so iconic
