I am using it 10 minutes and I already hate it since it's too good.

About 20 years ago they was an early XDG /Compiz plugin called ‘literal focus’ - as a joke, it only focused the focused window. It’s amusing to see this technique being used more practically.

I don't have a Mac, but even if I did would I have it constantly watching me? No. This sort of thing creeps me out.

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

Works pretty well, probably too resource heavy to just always keep on. Suggestion: give the user a shortcut key to close the app in case the blur goes haywire on them.

Hi - thanks for the feedback. I've improved CPU usage with the latest release. I'll look into a kill switch.

Not that I have particularly bad posture, but…

Not all of us have web cams, or are willing to tolerate them from a security perspective. [apologetic grin]

Highly recommend the LookAway app if you are on macOS and looking for something encouraging you to take breaks and maintain good posture.

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".

I don't think Linux has an equivalent of Apple's vision API, and if it does I guarantee it's not as robust and isn't baked-in to every Linux distro (the way Vision is baked-in to every Mac released after X date).

That alone will likely prevent this from just being a "convert to Linux" vibe session ... which is unfortunate, as I would LOVE to have this on Linux.

PlatoIsADisease 1/25/2026||

Yep, this is the bottleneck. Otherwise I would have done the prompt myself.

I literally hire interns to vibe code... sooo.. I don't need to be sold.

lol, whenever I am hacking intensely, I am lying down on my bed with laptop tilted with the perfect angle.

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

Would be cool to see integration with something like Upright Go or other sensors you place on your back that detect tilt etc.
