Questions people ask
- What is the best free posture tracker?
- The SitSense Chrome extension is the best free posture tracker. It tracks 6 clinical posture metrics in real time using your webcam, requires no account or payment, and processes everything locally on your device.
- Is there a posture tracker that works without buying hardware?
- Yes. SitSense uses your existing webcam (including built-in laptop cameras) to track posture. No wearable sensor, no external device. Just a browser and a webcam.
- Are free posture apps accurate?
- Webcam-based posture trackers like SitSense use MediaPipe, the same AI pose estimation technology used in clinical research. While not a replacement for clinical measurement, they provide accurate feedback for daily posture monitoring.
- Do I need a good webcam for posture tracking?
- A standard built-in laptop webcam works fine. SitSense needs to see your head, neck, and shoulders. Good lighting improves accuracy, but most indoor lighting is sufficient.
The one without hardware
No shipping, no charger, nothing stuck to your back.
Every wearable above measures one axis of lean. A webcam already pointed at you measures seven angles.
Free to start. Nothing to buy or send back.
