Slouch Sniper
Dims your screen the moment you slouch. Webcam-based, on-device, no wearable.
PostureMinder is a simple browser reminder: it pings you every few minutes to sit up. That is useful for awareness, but it is not the same as posture detection. Slouch Sniper responds to the actual bad habit.
Timer-based Chrome reminder
