Let's improve your posture

SitWit will notify you as soon as you lean too far forward or back. This way, a bad sitting posture can be improved.

Reduce back, neck and shoulder pain

Studies have shown that by improving your posture you can reduce pain in your (lower) back, neck and shoulder, by strenghtening your muscles. A good posture will also reduce headaches and stress levels.

How it works

SitWit uses the webcam in your computer to analyze your sitting position. The images are processed in real time and are not stored anywhere.

By calibrating the SitWit, you learn SitWit about your good sitting position. Based on this, SitWit can let you know when your sitting position is correct or not.

Know when you are sitting badly

SitWit calculates a score that indicates how good you are at the moment. As soon as the score gets too low, the app will send you a notification. This way you work towards a better posture.

    SitWit is really magical. I am surprised to find that every time I get a notification I am actually slouching. For me, that's enough reason to use it.

    What I like about this app is that it's surprisingly discrete but proactive when it needs to be.
