FlexAthlete turns a 20-second morning check-in into a readiness score that respects hypermobile joints, then builds your run, strength, and recovery around it.
Download on the App Store iPhone and iPad. Works fully offline.Generic recovery apps treat a flare like a bad night of sleep. FlexAthlete weighs joint pain more heavily, caps your score during a flare, and never pushes you toward injury.
A 0 to 100 score from three simple questions, weighting joint comfort above energy and sleep. Fully offline.
5K, 10K, and half marathon builds, including a gentle 20-week conservative half for fragile joints.
Live cadence with an optional metronome to shorten your stride and cut impact through every joint.
Isometric and eccentric programming across Foundation, Build, and Maintain phases.
Log flares and surface pattern insights so you learn your own triggers over time.
A plain-language read on your day, athlete to athlete, based on your readiness and recent trend.
Three steps, every morning, under a minute.

No. FlexAthlete is offline-first and works with the morning check-in alone. If you wear a device, the readiness score can use it to refine the result, but it is never required.
No. FlexAthlete is a training tool, not a medical device, and does not diagnose or treat any condition. Always follow guidance from your own clinicians.
Joint comfort is weighted above energy and sleep, and the score is hard-capped during a flare and for a few days after, plus after three consecutive low days it forces a recovery day.
No. Your check-ins, runs, and flare history are stored only on your device. See our Privacy Policy.
