30-Minute Posture Reset Timer
Ergonomics research generally recommends interrupting sustained static postures every 20–30 minutes. This timer fires every 30 minutes as a cue to sit tall, roll your shoulders back, and check your alignment — a quick 20–30 second reset that prevents the gradual postural collapse that causes end-of-day neck and back pain.
How it works
The timer counts down 30 minutes. When it fires, take 20–30 seconds to consciously reset your posture: sit tall, shoulders back and down, head over your shoulders, feet flat on the floor. Restart and repeat.
POSTURE TIP
For the posture reset to work, you need to know what your baseline looks like. Use unhunch to calibrate your personal correct posture once, then the 30-minute reminder becomes a check against that standard.
Want continuous posture monitoring — not just periodic reminders? unhunch watches your head and shoulders via your webcam in real time and alerts you the moment you slouch. $14.99 lifetime access, 7-day money-back guarantee.
