Meet the Upright Go: a wearable device that tracks and improves your poor posture. It vibrates every time you slouch. The companion app also lets you track your sitting habits. To get started, turn your Upright on, put it on, and you will get posture feedback immediately.
The companion iOS / Android app keeps you updated on your progress. The device weighs only 12 grams. Its battery lasts up to 10 days. Expected to ship in June.
