Show HN: I made an app that blurs my screen when I slouch

Such a creative solution to what might seem like a small, but really important, problem! I love how precise and responsive the blur is.

Thanks so much for making Posturr. It definitely deserves more recognition!

last time I went to a physiotherapist he said "the best posture is always the next one"

He said it's better to keep shifting positions than to maintain one for a long time, even if it's considered a "good posture"

That's cool! Is this implemented using a Swift feature?

Yes, it actually uses a private API: CGSSetWindowBackgroundBlurRadius. There's public APIs, but they do not provide as gentle of a blur as I was hoping to achieve. iTerm actually uses this same API: https://github.com/gnachman/iTerm2/blob/master/sources/iTerm...

Ah, that makes sense. Good to know iTerm does the same thing. Thanks for sharing the reference!
