Every chapter of the loop, in one app.
Each feature page is a deep-dive: what it does, what it doesn't, which vertical uses it, and the honest limits.
AS program
BASDAI, BASMI, a flare log, a clinician PDF, and a biologics directory. Free for anyone with an ankylosing spondylitis diagnosis, with no end date.
AI coach
A GPT-4o coach that answers from your own logs — today's symptoms and BASDAI, your last workout, last meals, last injection, recent HRV and sleep — by text or voice.
Nutrition
Log food by photo, barcode, or USDA search. Every entry keeps 84 nutrient fields, and the day is scored against targets you can change.
Body scan
Three private phone photos — front, side, back — with visual form notes and a history you can compare over time.
Workouts
Generated plans from your goals, equipment, and experience, with a hard rule for AS: a flare day becomes a mobility-only session.
Recovery
HRV, resting heart rate, and sleep from Apple Health or Health Connect, shown next to everything else you log, with a readiness number you can also enter by hand.
Voice
Talk to the coach instead of typing, and have replies read aloud. Built for hands that hurt in the morning.
