I spent the last few months waking up every single morning with a stiff neck and a rigid spine. Occasionally, I would get neck spasms that would stay with me all day, making it hard to focus while I was at my Mac, working. I finally realized that I wasn't just leaning forward or slouching. I was freezing. I was sitting in the exact same rigid position for hours without shifting an inch.

I started exploring how other people were using motion sensors and began reading about what pitch, yaw, and roll actually signify. Initially, I just wanted to build a tool for myself to understand my own patterns. I had no intention of making an app to publish to the App Store or TestFlight.

The first version was a simple menu bar utility. I programmed it to play a small audio tink whenever I stayed too still. It was a failure. The sound was so annoying that I ended up quitting the app just to find some peace while working.

That annoyance led to a better approach. I realized that awareness should be quiet and visual. I spent three months using the tool privately before releasing it, evolving it from that basic utility into a notch interface that lives at the top of the screen. I added:

* **3D head visualizations**: To see my head orientation and tilts during work.
* **Session charts**: To look at my movement trends and balance scores after a day of work.
* **Silent Nudges**: Visual cues in the notch that show when I am drifting or stuck.

I noticed my habits changing naturally without the pings. I started shifting my head, stretching, and getting up to walk more often because I was finally aware of how still I was being.

It is important to be honest. A piece of software or a mere app cannot fix tech neck or a stiff spine or bad postures. These are physical issues that require stretching, the gym, or medical attention. This app is only for creating the **conscious awareness** needed for you to take those actions yourself.

I do not want people to use this app forever. It is meant to help you become so aware of your sitting habits and head movement that you eventually don't need the tracking at all. The day you feel like you can delete Headjust because you are naturally moving on your own is the day it has actually worked.

I built something I hope you eventually stop needing and uninstall (free!)
