Maintaining proper posture all day long is important if you don’t want to develop neck and back pain. ALEX is a smart posture tracker that measures your neck angle and head position and vibrates when you slouch.
This discreet wearable device sits around the back of your neck and lets you monitor your posture in real-time. The battery lasts up to 7 days without recharging. Costs under $80 at this time.
