Verdict

The Jawbone UP3 is a lightweight, screenless fitness tracker weighing 29g and measuring 220 x 12.2 x 9.3mm, featuring a medical-grade hypoallergenic rubber strap and anodized aluminum construction. It utilizes an advanced multi-sensor platform—including a tri-axis accelerometer and bioimpedance sensors for heart rate, respiration, and galvanic skin response—to provide detailed tracking of steps, calories, and advanced sleep stages like REM. Key advantages include its stylish, discreet 'jewelry-like' design, a battery life of up to 7 days, and the highly-regarded Smart Coach app that offers personalized health insights. However, it lacks an on-device display and GPS, does not support on-demand or continuous heart rate monitoring during exercise, and has a fiddly, sometimes insecure clasp mechanism.
