Your posture coach that buzzes when you slouch. Tallwise is a light, soft sensor that sits on the back of your neck and gently vibrates the moment you start to hunch over your laptop or phone. Straighten up and it goes quiet.
- Real-time reminder: feels the angle of your upper back and vibrates when you lean forward.
- Calibrates to you: sit in your best posture, press once, and Tallwise remembers it.
- Barely there: skin-friendly silicone, about 90 g, wear it under or over a t-shirt.
- Lasts all week: around 7 days at 4 hours a day, USB rechargeable.
- Made for desk days: work, study, gaming, reading or long video calls.
Tallwise is a posture reminder for everyday comfort, not a medical device.

Hours at a screen add up. Your neck feels every one.
You only notice the slouch when it hurts
Deadlines, lectures, late-night study sessions. Your head drifts forward, your shoulders round, and by evening your neck and upper back are tight and sore.
A gentle buzz catches it in seconds
Tallwise feels the change in your upper back and vibrates softly. You straighten up, it goes quiet. Repeat for a few weeks and sitting tall starts to feel natural.
Set up in 10 seconds. Better posture all day.
Put it on
Rest the soft silicone band on the back of your neck. It sits flat, even under a shirt.
Sit tall and press
Sit in your best posture and press the button. Tallwise remembers that position.
Feel the nudge
Slouch and it vibrates gently. Straighten up and it goes quiet. That's the whole habit.
