Train with your joints, not against them. A 20-second morning check-in turns into a readiness score that weighs joint pain more heavily, then your runs, strength work and recovery are planned around it.
Download on the App Store iPhone and iPad. Available in English, German, French and Spanish.Generic recovery apps treat a flare like a bad night of sleep. This app weighs joint pain more heavily and caps your score during a flare, so it suggests easier sessions when your joints need it.
A 0 to 100 score from three simple questions, weighting joint comfort above energy and sleep. Works fully offline.
5K, 10K and half marathon builds, including a gentle 20-week half marathon option.
Cadence targets with an optional metronome to help you shorten your stride and reduce joint impact.
Isometric and eccentric programming across Foundation, Build and Maintain phases, with demo videos.
Log flares and see pattern insights, such as typical flare length and most-affected areas, so you learn your own triggers.

No. The readiness score comes from the morning check-in alone. The app does not connect to wearables or Apple Health.
No. This is a training tool, not a medical device, and it does not diagnose or treat any condition. Always follow guidance from your own clinicians and stop if something hurts or feels unstable.
Joint comfort is weighted above energy and sleep. The score is capped during a flare and for a couple of days after one, and three low days in a row trigger a suggested recovery day.
Your check-ins, runs, plan and flare history are stored on your device. The only exception is the Premium AI coach: if you allow it, your coach messages and training context are sent through our server to Anthropic to generate a reply.
