Smart Posture Trainer — Vibration Slouch Reminder

A small sensor that sits on your upper back and buzzes gently the moment you start to slouch. No app, no straps, no nagging notifications — just a quiet nudge so you notice and sit back up.

Set your upright position once when you put it on, then forget it's there until it reminds you. Light enough to wear under a shirt at a desk, in the car or on the couch. USB-C rechargeable and lasts a full working day on a single charge.

It's a reminder, not a treatment. It won't fix an existing back or neck problem — if you have one, see your physio or GP. What it does is make you aware of the slouching you don't notice.
