It was about a year ago this time that Fitbit released a new fitness tracker, the Fitbit Ultra, so now would seem like as good a time as any for a refresh. Indeed, the company just announced the Fitbit One, which will replace the Ultra, and which adds a "silent" vibrating alarm to wake you up in the morning. (Hmm, where have we seen that before?) Though the alarm is clearly the marquee feature here, the One also steps up to Bluetooth 4.0 connectivity, allowing the data to sync to your phone automatically. Additionally, it sports a slimmer, flatter design (read: it looks less like a clothespin). The tracker is also splash-resistant, though not water-proof, so don't even think of taking it in the pool with you. Other than that, it does the same thing as the last-gen model: it counts steps, flights climbed, calories burned and tracks your total mileage. And, of course, the device syncs with a personalized website, where you can log your meals and view all your stats in easy-to-read graphs.
The Fitbit One will arrive in mid-October for $100. If that's too pricey for you, the company also introduced the Fitbit Zip, a dumbed-down tracker that's available now for $60. Though it's every bit as water-resistant as the One, it offers just basic functionality (i.e., tracking steps taken, distance traveled and calories burned). Meaning, if the silent alarm or even the altimeter is of interest, you'll want to shell out for the pricier Fitbit One. Oh, and one other big distinction: the Zip has a replaceable battery, rated for up to six months of use. As we said, the One won't be around until later in the fall, but for now we've got a few publicity photos for your perusal.%Gallery-165301%%Gallery-165302%
