SitApp: Posture Reminder
Sit straight, feel better
Only for Mac
Free · In‑App Purchases
Mac
Free up to 60 min/day. Your Droid catches slouches the instant they happen - all on-device, with no visual data leaving your Mac. Sit straighter starting today.
SitApp is a friendly posture coach for your Mac. It runs quietly in the background, watches how you sit through your webcam, and gives you a gentle nudge when you start to slouch.
Most posture apps just buzz at you on a timer. SitApp is different - your Droid actually learns what good posture looks like for you. Show it your best posture, show it your worst slouch, and it builds a personal model that knows the difference.
WHY POSTURE
We sit for eight, ten, twelve hours a day. Necks creep forward, shoulders curl, lower backs ache. Most of us only notice the damage years later. A small nudge in the moment, repeated thousands of times, adds up to a real shift in how you sit.
WHAT YOU GET
- Real-time posture monitoring from your webcam
- A personal AI model that learns your unique posture, not someone else's
- Gentle, customisable nudges when you slouch (mini window, alert overlay, tray Droid, or full screen)
- Break reminders that fit your work rhythm
- Multi-monitor support
- Dark mode
- Daily and weekly summaries so you can see your progress
YOUR PRIVACY
SitApp processes every frame locally on your Mac. No visual or image data ever leaves your computer. No frames are uploaded, no screenshots, no biometrics sent to a server. The only things we sync are your settings and aggregated daily totals (how long you sat, how often you slouched) so they are available any device you use.
The camera light will turn on during calibration and monitoring. That is normal - it is the webcam being used locally, not data being sent anywhere.
WHO IT IS FOR
Anyone who spends serious time at a desk: developers, designers, writers, students, finance people, anyone in back-to-back meetings. If you have ever caught yourself hunched over at 4pm wondering why your neck hurts, SitApp is for you.
GET STARTED
Open the app, take 30 seconds to calibrate (a few good postures, a few slouches), and let your Droid take over. You will get a nudge whenever you drift. Over time, you will need it less.
Sit a little straighter. Feel a little better. That is the whole pitch.
