iPhone
Get your bike fit dialed in — without paying for a professional fitter every time.
Posely uses on-device AI pose detection to read your cycling position from a
short video, then measures your knee, hip, and back angles and gives you
personalized recommendations to ride more comfortably and efficiently.
KEY FEATURES
- Record a short video on your stationary trainer
- On-device AI measures your knee, hip, and back angles
- Personalized saddle height and reach recommendations
- Pain Diagnosis — connect discomfort to possible fit causes
- Find My Size — match yourself to a growing catalog of bike geometries
- Save analyses, track changes over time, export PDF reports
- Bike notes to keep track of your setup
PRIVACY-FIRST
All video analysis happens entirely on your iPhone. Your videos never leave your device — only the numerical measurements are saved, so you can track your progress over time.
HONEST ABOUT ACCURACY
Your camera setup affects measurement accuracy. Posely tells you how to position your phone for consistent results and is transparent about what it can and can't measure. Small changes in setup can shift recommendations by a few millimeters.
NOT A REPLACEMENT FOR PROFESSIONAL FITTING
Posely is a screening and self-assessment tool. For persistent pain, chronic issues, or competitive optimization, please consult a certified bike fitter or healthcare provider.
