CycleFit exists for one reason: most fitness apps treat your menstrual cycle like an afterthought. We treat it like the most important piece of programming data you have.
Every woman who has ever followed a generic training plan already knows: the workouts that crush you in week 3 felt easy in week 1. The PR you missed during luteal was a PR you owned a week earlier. The recovery you needed during your period was never built into the plan.
CycleFit was built to fix that. Our app adapts every workout to the phase of your menstrual cycle, using research from women's sports science. You stop guessing. You stop over-training in luteal. You stop wasting your ovulation peak. You start compounding fitness instead of fighting your own body.
We're iOS-first because that's where we can ship the best experience today. We'll be on Android soon.
The people behind every workout, every article, and every line of code in the app.
