Sitting up straight at my desk, chair locked, perfect posture? I’m doing nothing, maybe looking through System Preferences to change the system highlight color.

Sliding down in my chair like jelly, with my shoulders where my butt should be and my head resting on the lumbar support? I’m building the next iPhone and it’ll be done by 2 AM.

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" your skills can be easily transferred and used to cross platforms boundary and code such useful app in a weekend or so.

Jevons paradox is indeed working (https://en.wikipedia.org/wiki/Jevons_paradox).

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 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!

ps -- I added two feature requests and commented on another on the repo.

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.

Years back, we did a couple of whimsical prototypes along those lines (using J!NS MEME, smart glasses): https://youtu.be/LXIY2g-twOA

Can't really afford to play with an app that would have such an obvious hit on productivity and mental clarity.

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 (?)

However, I was not familiar with Swift, the app was more or less vibe coded.

My next goal was to learn swift patterns to refactor the app into something that was understood and robust.

I will be reading though your sources to understand production quality Swift!!

Still, always good to see someone push out a new app. Well done.

I've noticed that the app tends to use 15% of my CPU constantly. I wonder if there is room to improve efficiency so that the app does not hog resources.

The blurring of the screen is a much better idea.

I tried opening by right-cliking on the app file, holding option, etc.

I'm on Sequoia 15.7.3 (24G419)

I guess this app won’t catch me slouching then.

Congratulations! I love seeing people express themselves to release things that were previously not economically viable to prioritize

Forget worrying about a 10x dev, Claude Code with the Opus 4.5 model has turned me into a 100x developer even in software stacks I'm not even familiar with. And with playwright-mcp its completely absolved the need for UX designers in my workflow because I just point playwright-mcp at an already established and A/B tested website for its UX principles. This gives me results far beyond what v0, lovable or Claude Code would come up with on its own.

No back problems as there's no weight on my spine. No carpal tunnel issues, as my wrists are always flat. No fatigue from holding my body at right angles for hours at a time.

The downside is I look like a total slacker in the office, especially to narrow minded image conscious managers who expect me "to act professionally."

For example, even if you sit perfectly upright, if you have anterior pelvic tilt, it can change the whole dynamics of your spine, that the cervical segment takes a lot of load that it isn't supposed to do.

Or with bad habits you can reprogram your neuromuscular system that it uses the wrong muscles to maintain posture, that can lead a series of problems long term.

If you have back/neck pain or tension that does not resolve in 1-2 weeks, go to a physio.
