You can measure my productivity by how slouched I am.
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.
This is how things get built for me as well. I have a standing desk and like using it occasionally but if you see me standing at it you can bet I'm doing something typical like emails or chat and not thinking deeply.
My productivity is generally measured in how much time I sit on the porcelain thinking throne first.
Truer words have never been spoken. That and planning out your day & thinking through problems in the shower.
If you delete social media, and leave your phone away from your person all day with notifications turned off, you can have these moments all the time it turns out.
Considering how much more productive these moments are for me than the bullshit I used to do on my phone and social media, it was an easy decision to make.
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.
With a faucet my good friend!
My neck is screaming in empathetic pain for your future neck!
Sounds like you're literally the target audience for this app.
Not if there is a hard positive correlation between productivity and slouching, like they say.
this is the way
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.
Yeah, most of my computer use is with a properly adjusted desk setup with external monitors and while it doesn’t bother me to use a laptop to jot down some notes or for a short study session, if I try to do “real” work at all I quickly become uncomfortable. A cheap folding laptop stand (which elevates the laptop enough that the middle of its screen is eye level) and wireless KB+mouse dramatically improves comfort (and productivity) but the tradeoff is that you need a table or other sizable, stable flat surface.
The exception is if there happens to be a reclined-position chair (IKEA POÄNG or similar) around; this gives back support and reduces neck craning enough to make longer sessions more viable, but it’s far from a given that this kind of seating will be available.
When working at a desk I put my 16-inch MacBook Pro on a stand and use an external keyboard and trackpad.
I don't like adapting my monitor layout when moving between working environments.
Instead of an extra monitor, I have an iPad Pro on a stand.
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

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.
I use the Nexstand K2 (well, the Chinese knockoff I got for $5), and I bent some coat hangers to attach to the top of the stand and tilt the laptop forward. I’m a tall guy, and the top of the screen is even with my eyes. Bonus is that with an X1 Carbon, the Lenovo M14 or M14d fits perfectly over the top of the keyboard.
The whole setup fits into a drawstring gym bag.
My Apple Vision Pro has all that, and it’s perfect for posture when using a MacBook.
Isn’t the Vision Pro rather front loaded in terms of its weight distribution? Seems like you might just be trading one ergonomic problem for another.
It’s not really, with the new dual band which changes the weight distribution. If you lean back a lot it’s obviously going to rest on your face then, but that’s a good way to avoid bad posture too.
Still, it’s not for everyone. I use it with my AirPods Max comfortably, I have a sturdy neck. I don’t think my wife could pull it off.
Yeah- this and the upcoming steam frame seem like the best options today.
There's something very attractive for me personally about the sunglasses form factor.
Safer in public, draws less attention, more portable, less headset fatigue, etc.
But obviously trading quality and features.
Also AVP is like $3k, steam frame will probably be $800+, xreal are like half that
> But obviously trading quality and features.
For me it’s like settling for a CRT after trying a 4k TV in terms of visuals, but with the form factors reversed.
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" 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 can't seem to open it. It keeps saying "Apple could not verify “Posturr.app” is free of malware that may harm your Mac or compromise your privacy.".
I tried opening by right-cliking on the app file, holding option, etc.
I'm on Sequoia 15.7.3 (24G419)
Sounds like a good idea but “good posture” meaning being upright is just such an outdated and incorrect thing. Be comfortable, relax in your chairs, it’s fine.
I wonder if this is less about “bad posture” and more about how people unconsciously optimize for stability when thinking deeply. When I’m reasoning through something hard, I tend to lock into whatever position minimizes micro-adjustments - even if it looks terrible ergonomically.
Anyone else with progressive lenses just think "I already have this"?
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...
Word of warning: the Embody chair does not have front-to-back adjustments for the armrests. They will be pretty useless unless you like having your keyboard close to the edge of your desk.
Totally a tangent here but it amazes me how a company as big as Herman Miller could screw a product page up so much by not even having a picture of the damn product.
Something might be wrong with your client (ad-blocker, NoScript maybe?) because there a ton of pictures on that page.
Ha, yep you're right. How bizarre, wasn't a browser ad block, it was adguard dns blocking a ton of tracking scripts needed to show the images.
It's the first thing on the page. Your browser is doing something funky.
The embodiment of overpriced and mediocre
if im not sitting on my right foot with left knee under my chin my thinking takes a hit, but i also have to constantly switch how im sitting so i dont get annoyed. its hard not to slouch/melt into whatever im sitting on and i think the only way to offset all that is the gym.
Love it - I did something like this for when codex is done - a script runs to detect if I’m at my computer or not and then notify my phone if I walked away that it’s done - mostly so I can get back to slouching ;)
Guzzles my CPU, cool though! Would use if it didn't eat up half a core to boot.
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.
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.
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.
Care to share an example of this backrestless chair? Is it like a regular chair just without the backrest, or has some other differences? Does it have armrests for example, and if not - does it bother you?
I went with an overkill approach at first (as I often do :-) and bought some expensive nicely designed "active chair" / stool that was adjustable high enough so that I could lean on it even when using my desk as a standing desk. It was interesting, but not a game changer at all for me. I don't use standing desks now at all.
But what I have now is this:
https://www.amazon.com/dp/B002FL3LY4
Just don't assemble the backrest at first. If sitting up straight, I just lean wrists on my keyboard wristpad and part of forearms on the desk, no armrests needed either.
Edit: I still use my height-adjustable standing desk, but now it's value is that I could adjust it for the perfect height for my sitting-up-straight position (so no chair armrests needed) and it's been fixed at that height for the last 7 years...
Not sure which one the parent was referring to but personalizing I've been using one of these for more than a decade at this point (I'm sitting on it right now) https://www.varierfurniture.com/en/products
The one I have does have a backrest but because of the way it's shaped you don't actually use it to slouch. It's more there to support when you lean back and want to take a break from typing or something like that.
A codebase search for "claude" only has 1 hit in the code (the markdown that you referenced) and 4 commits which include the word in the commit message, or one commit includes .claude/ in the git ignore. See https://github.com/search?q=repo%3Atldev%2Fposturr+claude&ty...
Same with a codebase search for "anthropic"
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.
Notarization is mostly a glorified malware scan. There's no Apple engineer auditing what's being sent for notarization. Even clever malware can evade notarization scans and be distributed as a notarized binary, it has happened in the past [0]
There's no better way for auditing such an app than having the code easily available and looking through it, and compiling it yourself. Which is already the case here.
[0] https://thehackernews.com/2025/12/new-macsync-macos-stealer-...
Your link says that Apple revoked the certificate used to sign the malware by the time the story was published.
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
Do you expect this programmer is in cahoots with Anthropic?
The opposite, actually: that the code tricks the LLM.
While I disagree with you, thank you for sharing your decision-making process: you're probably not the only one who thinks this way.
In general, would you pay for a notorised build of free software, if you had use for that software, even if an un-notorised build or the source code were available?
I seriously doubt that he actually would. And in that unlikely event he'd be in a miniscule minority. Not a good open source monetisation strategy.
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!
What prevents you from compiling it if it is open-source?
That's what I do with every project delivered as docker image. I rebuild the app and the image.
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.
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
Would be cool to see integration with something like Upright Go or other sensors you place on your back that detect tilt etc.
This is cool, I built something similar a while back. I originally wanted the screen to dim when I slouched but I couldn't get access to dimming on OSX. I ended up just playing a noise when I slouched. It became so distracting I stopped using it.
The blurring of the screen is a much better idea.
Why use a proprietary stack for building this when there is a far more capable open ecosystem available at your fingertips?
do any more open applications like this exist? The idea seems great
Black Mirror is nearly here.
Install a pull up bar in your room. It will fix your back better than anything else.
1 min plank in the morning is a big help too
So now I gotta squint while I slouch!
One thing I learned from my physio: in your spine, everything is connected.
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.
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. >.<
If I’m not wearing my glasses the screen blurs organically.
Doesn't the screen already go blurry when you're not wearing your glasses?
It's a spectrum I'm trying to avoid it getting that bad
I think he's joking
I wish
Staying in upright posture for too long is also not good for you.
I would pay $10 for this.
Satire i hope
How can you tell if a short person is slouching? Or a tall person?
I'm not the author, but I assume it benchmarks the highest height of your head, blurs from there, and updates its baseline if you ever appear higher.
Meaning that the way to have "perfect posture" is never to sit up straight in the first place :-)
If you assume a person’s chair height and desk height are both set optimally, then I guess the person’s height doesn’t matter for this detection.
Plz make a Windows version :)))
Anyone want to vibe code this to work on linux or M$
Great contrarian indicator for when people say that vibe coding is not "real development work" or economically viable/a job in the future - here is someone asking if another person can vibe code something for them that is single file of swift, the prompt could be as simple as "convert this to linux".
Great, now I'll get sick eyes too
