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!

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).

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 w…

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?

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.

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.

My productivity is generally measured in how much time I sit on the porcelain thinking throne first.

My neck is screaming in empathetic pain for your future neck!

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…

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.

Sounds like you're literally the target audience for this app.
