Show HN: An on-device Mac app for real-time posture reminders (apps.apple.com)
4 points by data-leon 98 days ago
Built this because I wanted a simple posture app I could leave running all day without extra friction. It runs locally on Mac, watches for posture drift in real time, and nudges you when you start slouching.

I’d especially love feedback on accuracy, privacy expectations, and whether the reminders feel useful in practice.

Cheers!
