It works just like a regular watch, but syncs via Bluetooth like a smart fitness tracker. Fitness on your wrist has never been more convenient or more stylish than on the Activite Pop, an everyday watch with fitness smarts. The device syncs with iPhones and Android phones over Bluetooth. If having a screen isn’t a priority, the Jawbone Up24’s superb app, clever advice and comfy fit are hard to resist. The watch is swim- and shower-friendly, has a built-in pedometer, and a variety of quirky apps are available to download. Storage is limited to eight apps at a time and the watch requires charging twice a week. The competition is advancing fast, but the fashionable, functional and more affordable Pebble Steel’s conservative approach puts it at the top of the smart watch heap. The fitness band adds continuous heart-rate tracking to the features already available in the less-expensive version for just a bit more money. Resting heart-rate readings are reasonably accurate. Design and fit aren’t ideal for glancing at your heart rate. Active exercise causes accuracy to drop off, and it’s not shower- or swim-friendly. Heart-rate coaching and goal-setting isn’t intuitive. Fitbit’s Charge HR adds heart-rate tracking to an already solid fitness band at a great price, but all the kinks don’t feel fully ironed out yet.
