Postura

Setup. Turn on the camera, then Calibrate while looking at the screen normally. Postura offers to recalibrate at the start of a new session, since your seat or camera may have moved.

Tracking. Head down = studying. Head up or away = idle. Hit Start to make it count.

Earning. Studying banks break time. Looking up or away for 15s straight auto-starts a break, counting down from your bank — if it hits 00:00 it keeps going into debt (down to a limit of -15:00) until the break ends.

Manual mode. "Manual breaks only" turns off auto-breaks — you start breaks yourself with the button. A manual break can still run into debt the same way if it counts all the way down.

Glasses. Calibrate with your glasses on. Postura blends eyebrow position with eye position to soften the effect of lens glare, but strong reflections can still throw tracking off — even, front-facing light helps.

Keep it visible. If Postura is in a background tab or minimised and the camera stops updating, tracking pauses and study time isn't counted. Breaks keep counting.

Internet. Postura needs an internet connection to load its face detector each time you open it.

Privacy. Your camera video is processed on this device and is never uploaded or stored. Postura loads its face detector and fonts from public CDNs, which can see your IP address.
