The Jawbone Up3 features the handiwork of renowned Swiss designer Yves Behar. It has a slim anodised aluminium casing with a rubber wrist strap, and is available in silver, red, black, blue and gold.
The silver and red versions have a twisted cross design on the casing, while the rest have diagonal lines running across the top of the casing. But the device does not have a display.
I reviewed the gold version and it drew admiring looks from friends and colleagues.
Like many fitness trackers, the Up3 has limited waterproofing capability. You can wear it when washing your hands or taking a shower but not when you go swimming.
WATER RESISTANCE: Splash-proof
BATTERY LIFE: 4/5
VALUE FOR MONEY: 3/5
I found the clasp insecure and it often came undone when I tried to reach for something. And if you, like me, tend to toss and turn when asleep, the Up3 might end up on the other side of the bed when you wake up.
A new firmware update allows automatic sleep tracking. Before that, you need to switch it to sleep mode. It works but sometimes gave me a sleep time that was shorter by an hour or so.
It does not track your heart rate constantly, only the resting heart rate while you are asleep.
Fitness statistics, such as steps taken and distance travelled, were quite accurate. Compared with my calibrated Nike+ FuelBand, there was only a 4 per cent difference in readings.
The advertised battery life is seven days, but I found myself having to charge mine by the sixth day.
- VERDICT: The Jawbone Up3 is expensive, but it is feature-packed and the best-looking fitness tracker in this round-up .
