AI will not fix your posture in a week or replace a physical therapist. It can do three useful things: measure what a mirror misses, keep every result together and adapt your plan when your movement or symptoms change.
Solutions
Judging posture by eye can mislead you in both directions: a small detail looks alarming while a meaningful difference goes unnoticed. Pose analysis reads body landmarks from the camera image and turns them into angles. Instead of an impression, you get a result you can repeat in six weeks and compare.
A plan chosen at the start may no longer fit what is happening a few weeks later. One range improves, another lags, a new ache appears or you simply have a rough week, while a fixed routine stays unchanged. In Kallen, the model does not invent exercises. It reads your measurement history before every reply and proposes a specific change only when the data supports it.
AI does not diagnose or distinguish ordinary overload from a problem that needs a doctor. Every Kallen protocol therefore opens with its red flags, and the coach says plainly when you should be assessed in person while continuing to support you safely. Because you train unsupervised, dosages stay conservative, and you move to the next phase by meeting a capability rather than reaching a date.
No. You need a phone camera and a few meters of space. The range-of-motion tests use pose analysis from the image, and several need nothing but a wall or a chair.
Your history, plan and pain journal stay in your phone’s storage. Kallen has no accounts and no sync. Photos go through our server to an AI model for analysis, and the result comes back to your phone.
Specifics
Concrete answers to the specific questions people ask about AI and posture.
01
Pose analysis reads body landmarks from the image and turns them into angles, so you get a number instead of an impression. Kallen offers 7 kinds of scan, and 8 of its 34 movement tests are measured by the camera; the other 26 cannot be read from an image, so you run them with a written guide and a timer. That is accurate enough to compare one measurement with the next, not to diagnose anything.
02
Memory, and recalculating the plan. A set chosen on day one is exactly the same set in week six; the coach reads your whole measurement history before every reply and proposes a specific change when the data justifies one. The catalog holds 89 exercises and 24 protocols, and nothing enters your plan until you approve it.
03
No, and Kallen does not claim otherwise. AI cannot examine you with its hands, diagnose you or distinguish ordinary overload from a problem that needs a doctor. Each of the 24 protocols opens with the red flags that warrant an in-person assessment, and the coach names them plainly while continuing to guide you through what is safe.
Inside the app
Two screens show the full process: first, a measurement you can repeat, then guidance that uses the result.
The knee-to-wall test takes a minute and records centimeters for each leg. Repeat it the same way in six weeks to see what changed.
Ask about any exercise and get step-by-step technique plus a card with the prescribed dose, ready to add to your plan with one tap.
Measure your range of motion in Kallen, build your Movement Profile and follow the plan step by step.

01
Eight range-of-motion tests and ten movement checks you can do at home, the normal range for each, and what a stiff ankle, hip or upper back can overload.
02
Six checks before you pay for a posture app: measurement, plan changes, left–right comparison, red flags, privacy and dosing, plus where Kallen falls short.
03
Posture reminders fade into the background within a week. Why a short break with a ready-made movement beats one more prompt to sit up straight.
