I'm not sure how you can use a laptop with good posture. An external monitor at the right height seems like a necessity.

I'm also optimistic about monitors in the form of glasses- even less effort needed to set yourself up for perfect posture. But the sweet spot problem is still very much a thing from what I've seen- can't wait until it's normal for them to have eye tracking, foveated rendering and streaming, and be wireless.

I would love this but for detecting when I'm not wearing my glasses!

“If only the world had some way to remind be to wear my glasses … like going all blurry or something.”

I get you - but making it absurd is where my brain went immediately. >.<

Once launched, Posturr runs in the background and displays a brief "Claude Mode Active" notification. I haven’t checked the code yet, but what does the “Claude Mode” mean? Is it a poor naming choice? It implies that the local app is somehow connected to Claude (?)

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.…

Cool, thanks for the clarification. Indeed it's a good and practical idea for a small app. As other comments have said, (some) people might happily pay for this app.

I luckily won't need such feedback loop anymore, had some mild lower back pain show up over 10 years ago and bought a chair without a backrest that, after 3-4 weeks of struggling, trained me to sit up straight. Now I have some random cheap office chair with a backrest, but I rarely lean back to it. Funnily, I was going to give up using that "backrestless" chair after 2 weeks of inconvenience, but decided to give it one more week and then the magic happened :-) Mild lower back pain automatically gone.

I think the idea is wonderful, but a not-audited application that uses things like the camera is a “no go” for me. Get it notorized and ask for some money! I will gladly pay it (and I hope others will do it as well). Awesome concept: ergonomics and/or posture monitoring is a market opportunity for heavy users.

Are you serious? It's open source. And there's less than 1000 lines total. Get Codex or Claude to review it if you're paranoid.

The thing is that how do you know at the end of the day that the compiled binary hasn't been tampered with "extra code" besides what's in the repo?

I don't even think notarization gets rid of this problem neither, so the best you can do for this is compile it yourself. Maybe I'm wrong!

It's literally a single .swift file. Ask your LLM to audit it.

then I need to get someone to audit the LLM, which is considerably more difficult

Compiling it yourself is the best/only thing you can do if you really want to know what code went into a binary.

Go easy on the guy. Mac users are so used to overpaying for trivial functionality.
