Kallen – AI Mobility

Most mobility apps hand you a stretch list. Kallen measures you first.

Three photos. A few tests in front of the camera. From those, Kallen builds a 3D twin that stands the way you stand — and a 10-minute daily plan aimed at the two or three links that are actually holding you back.

MEASURED, NEVER GUESSED
• Full posture scan from front, side and back — every angle read for you
• Range-of-motion tests through the camera: no tape measure, no guesswork
• 34 functional tests for strength, balance and symmetry
• Feet, knees and your desk setup too — the whole chain, not just the spine

YOUR BODY, IN 3D
• A living twin that mirrors your own alignment
• Animated stories show what your pattern is doing to the rest of you
• Your measurements pinned to the muscles they came from

A COACH THAT REMEMBERS EVERYTHING
• Every scan, test and conversation builds one Movement Profile
• Patterns and left-right asymmetries the eye simply cannot catch
• 89 exercises, plus routines shaped around your body
• Mobility Snacks — one-minute resets that undo the last stretch of sitting

WHY TARGETED WINS
Stretching a bit of everything spreads your effort thin. The return is in the few links that actually give way. Finding them takes measurement.

PRIVATE BY DESIGN
No account. No sign-up. Nothing you enter is tied to your identity, and it all lives in the app on your phone.

The AI features are the exception, and you choose them. To build your plan, read your scans and answer you in chat, the Kallen app sends the data listed on the app's consent screen to Google LLC (Gemini API), which processes it for us and never trains its models on it. Photos are compressed first, we keep no copy, and you can switch AI off any time in Profile → System & subscription — the routine, exercises, timers and journal keep working without it.

Kallen is an education and coaching app, not a medical device. It does not diagnose or treat. If pain is severe or worsening, see a qualified health professional.

Subscription unlocks unlimited coaching, analyses and the full plan. Auto-renews until cancelled; manage in your App Store settings.
