Upright Go posture trainer

Fix your screen-slouch with this inch-long gadget that sticks imperceptibly to your upper back and buzzes when your posture slips, giving you a gentle reminder to sit or stand up straight. It connects to an app on your phone via Bluetooth, to track your improvement, and it won’t show under most outfits so you can wear it on the go. Best for: the gamer nephew Available from:
