Hi - thanks for the feedback. I've improved CPU usage with the latest release. I'll look into a kill switch.

I reduced the vision processing to about 10 fps as well as reduced camera resolution. I saw about an 80% reduction in CPU! Thanks for the feedback.

Thanks rdslw. I mentioned something similar on my blog post about this app here: https://tomjohnell.com/posturr-a-macos-app-that-blurs-your-s...

I love coming up with fun ideas and only having to worry about the fun part - not the toil. I would never have made this app without llm support.

I added compatibility mode that incorporates the public API. Give it a shot please. I welcome any feedback.

1.0.4 is release with better descriptions.
Re:A macOS app that blurs your screen when you slouch on Sunday January 25, 2026 @01:59PM (#46757012)
I've released 1.0.3 with compatibility mode to use public APIs. The blur isn't as good, but better than nothing!

Hi - this is the author. I can explain that, ha!

Right now I'm using a vision library to detect head height which was good enough. I went down a tangent where I hooked it up to my Claude Code instance to take a screen shot and have Claude Code assess how bad my slouch was. Claude would watch a folder for screen shots, read it in, and if it detected bad posture, write to a file the program was watching to adjust blur.

I did this weird work-around so I could use my Claude Code subscription as opposed to the API.

Anyways, it was too slow and Claude was a bad judge of slouchiness. Head height works well enough!

I'll clean this up.

Yes, it actually uses a private API: CGSSetWindowBackgroundBlurRadius. There's public APIs, but they do not provide as gentle of a blur as I was hoping to achieve. iTerm actually uses this same API: https://github.com/gnachman/iTerm2/blob/master/sources/iTerm...
