Fitbit Surge review. GPS and heart rate monitoring are welcome additions. Fitbit finally solved its sleep-tracking problem. Food database is robust and easy to use.

Design is better suited for the gym than the office. Slightly bulky body and strap. Pricey for an activity tracker, even one with GPS. The Surge solves some of Fitbit's problems with better food and sleep tracking, while adding GPS and heart rate monitoring to the mix. But its bulky, utilitarian design and high price will limit its appeal.

Pebble Time Round, though, lasts two days. That's two solid days, mind - 48 hours - which means you could wear it all day, all through the evening, and then on through the night for sleep tracking. Still, it means you'll probably have to travel with the charger unless you're gone for just the weekend.

There are a couple of things mitigating that compromise. Most significant is the fast-charging, which Pebble says squeeze in power for more than a day in just fifteen minutes. The idea, Pebble CEO Eric Migicovsky explained to me, is that you'd probably take Pebble Time Round off while you shower, giving it the length of your ablutions to recharge.
