While this seems to detect posture fairly well, the screen blurring doesn't work for me despite allowing what appear to be the relevant permissions. (macOS 15.1)

I had the exact same issue and have fixed it here: https://github.com/wklm/posturr

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

Does anyone ever reach a high level of productivity with correct posture? I can't.

Sure, but getting the right environment is a prerequisite. In my case it’s a Herman Miller Embody chair [1] that stops me getting into a bad position (it’s not impossible, it just encourages good posture). [1] https://www.hermanmiller.com/en_gb/products/seating/office-c...

I ditched all my HM chairs for a standard wooden chair. They just never felt right (maybe the non-forward-adjustable armrests had something to do with it), but boy are they good at selling you an expensive fantasy.

I’ve had chronic back problems due to computer use and back posture for 20+ years. This past year I bought an adjustable height desk and an Aeron chair to try and help, but I still slouch constantly without realizing it.

I cloned this a few hours ago and started using it and it’s amazing how effective the blur is! And it’s frustrating to learn how quickly I start slouching the second I’m not paying attention.

I’ll echo what I’ve seen others saying about how cool it is to see something come about due to LLM coding that likely wouldn’t have otherwise. Glad to see you actively working on it, and I’ll be using it every day!

P.S. I’ve been an iOS and Mac dev writing Obj-C and then Swift for 16 years now, so if you run into any issues that Claude isn’t sorting out feel free to reach out to me, you can find my contact via my GitHub which is in my profile (same username as hear). Also as I’ll be using this regularly, if I come up with any improvements I’ll be sure to open a PR!

How do you simulate the warm water?

Oh, lol, now I get your question. Yea, it turns out the silence and lack of distractions are what produce "shower thoughts", more so than the act of showering itself. Doing any relatively rote act like washing dishes, walking places, etc can also give rise to them. Not having a device in your hand to constantly steal your attention really helps though.

Showers are generally considered to be relaxing separately from the “shower thoughts” phenomenon.

Couldn’t the relaxation be a factor in generating shower thoughts?

I suspect that essentially none of our non-ancestors were predated in a hot spring, unlike walking etc, so there may be an environmental cue driven induced relaxation that doesn’t exist for many other activities.

Yea, you relax, and then your brain produces random thoughts about things.

I suspect it's just about getting the space to relax, which is why I frequently have thoughts when staring at the wall, or taking a walk, or washing dishes, or doing any other myriad activities which are relatively easy on brain processing.

How can you tell if a short person is slouching? Or a tall person?

I'm not the author, but I assume it benchmarks the highest height of your head, blurs from there, and updates its baseline if you ever appear higher. Meaning that the way to have "perfect posture" is never to sit up straight in the first place :-)

It has a calibration step

Congrats on the app. I'm seeing that "great-ai-unlock" is happening. I see in last month a lot of new software being codeveloped with claude/codex/gemini/you-name it. Before, it was too costly to do sth like the Posture app: here, you would have to know Swift and apple apis to write such tool. Would you be C# (very good) programmer with free weekend, and an idea: no cookie for ya. These days, due to "great-ai-unlock"…

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'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…

My dog could, but a person with adult proportions probably can't. For long-term use, a stand+KB is the only solution I know of https://www.kickstarter.com/projects/86285180/the-roost-savi... It's too bad that nobody on the Surface team has managed to crack this! I'd be much more interested in one if they had.

Laptop work is clearly not OSHA-compliant. I’m in France so it’s probably regulated a little bit more, but having a screen at eye height and a keyboard slightly under elbow height is the first line on the security analysis document (le DUERP), at least for tertiary workers. And far above “Floor must be non-slippery” and “The right to disconnect after 6pm”.
