Postural measures your posture from a front and a side photo on the device with Apple's Vision, and turns it into a Postural Age: your real age plus up to 8 years. Of the five markers it measures, only the two with published evidence count toward the score. A licensed physiotherapist reviewed the exercise routines, the form cues and the scoring thresholds. The years weighting is our own. Photos stay on your phone unless you share them. The scan, the number and the coach note are free.

I built this on nights and weekends. Two photos, front and side, and it turns your posture into one number you can track.
The part I keep having to explain is why it measures five things and counts only two. A licensed physiotherapist reviewed the exercise routines, the form cues and the scoring thresholds, and the years weighting is my own. Three of the five markers now count for nothing. They are still measured and shown, they are just worth zero years. One of those I found myself: Apple's Vision framework gives you a "neck" landmark that is really the midpoint between your shoulders, so it travels forward when your shoulders round. The angle I was using to detect rounded shoulders could not see rounded shoulders at any threshold. Dropping it took the worst possible score from 13 years added to 8.
Right call, and it cost me something. The number barely moves between scans now. Measurement noise sits around 0.7 years and most people's penalty lands inside that, so I am working on whether the underlying angles can show progress where the headline number cannot. I have not solved it.
Everything runs on the phone with Vision. No photo is uploaded unless you share one, which also means your scan history shows scores with no pictures attached. The scan, the number and the coach note are free; the daily routine and the history are behind a subscription.
Ask me anything, including why I did not just make the number more dramatic.
