Now you can develop a healthy, confident posture and count your steps at the same time. The ultralight Bluetooth Posture and Steps Tracker attaches to your shirt or bra strap with a clip or magnetic clasp, then monitors your daily posture and activity. It runs on a rechargeable battery that lasts up to 5 days, and sends the data automatically to your iPhone or iPad. You’ll see your “good posture hours," steps taken, distance traveled and calories burned. An optional “coach mode" vibrates every time you slump or slouch. Note: Not for use by those with a pacemaker.
