Today’s the day - SitApp is live on Product Hunt.

If you’re new here: SitApp is a desktop app that monitors your posture using your webcam and AI. When you start to slouch, it gives you a nudge to sit up straight. Everything runs locally on your machine - no video is ever sent anywhere.

The backstory

SitApp originally launched on Product Hunt back in 2021. It was rough around the edges, to put it kindly. I got busy with other things and the app sat neglected for years.

Then I discovered that people were still finding it, downloading it, and actually using it. Someone even wrote an article saying it helped fix their back pain. That was the kick I needed.

I’ve spent the past few months rebuilding SitApp properly. New AI engine, new UI, new everything.

What’s new

Here’s what shipped in the rebuild:

  • On-device AI posture detection - runs entirely on your machine. No cloud, no uploads, no privacy concerns
  • The Droid - a friendly on-screen companion that reacts to your posture in real-time
  • Streak system - daily tracking with milestone celebrations to build the habit
  • Weekly analytics - see your posture percentage and usage trends over time
  • Shareable progress cards - generate a branded card with your stats to share
  • Break reminders - nudges to stand and stretch (now free for everyone)
  • Multiple desk setups - different calibrations for home, office, standing desk
  • Dark mode - because of course
  • Mac, Windows, and Linux - works everywhere

Privacy first

This matters to me: all posture detection happens on your device. Your webcam feed never leaves your computer - no video is ever uploaded or processed in the cloud. Your posture stats (like daily scores and streaks) sync to the cloud so you don’t lose your progress, but the actual images from your camera stay on your machine.

Try it out

SitApp is free to download with a 7-day Pro trial. After that, the free tier gives you 1 hour of daily monitoring - enough to build the habit.

If you think the idea is cool, I’d really appreciate a vote on Product Hunt. It makes a massive difference for a small indie app.
