Slouch Sniper
Dims your screen the moment you slouch. Webcam-based, on-device, no wearable.
Posture Sensei is one of the most aggressive posture apps: camera tracking, on-device AI, game characters, and a screen lock after bad posture. It is a bold idea. Slouch Sniper is the same concept made calmer and more appropriate for a work laptop.

Public source notes
Where Slouch Sniper is strong
- The screen dimming is professional, no anime characters or game overlays on a work laptop.
- Windows support covers a much larger audience than Mac-only tools.
- A dim clears the moment you sit up; a hard lock can interrupt unsaved work or video calls.
- Easier to justify running on a company machine or in a professional context.
Where Posture Sensei is strong
Posture Sensei is one of the most aggressive posture apps: camera tracking, on-device AI, game characters, and a screen lock after bad posture. It is a bold idea. Slouch Sniper is the same concept made calmer and more appropriate for a work laptop.
- Posture Sensei is more intense. A hard screen lock is harder to cheat than a dim.
- Game mechanics and character damage can be motivating if high-pressure feedback is your style.
- Memorable and distinctive if you want posture correction to feel like a challenge.
How it works
Your webcam detects posture in real time, entirely on-device. The moment you slouch, the screen dims. The moment you sit up, it clears. No app to check, no score to interpret.
- On-device AI, no cloud, no streaming
- Mac and Windows, no wearables
- $19lifetime (price will increase to $38)
Bottom line
If your posture problem happens while staring at a screen, the correction should happen on that screen.
