Larklife fitness tracker syncs your data over Bluetooth, knows when you're running instead of walking!!

In case you haven't noticed, fitness gadgets are having something of a moment right now. The past year alone has seen the launch of Nik

e's FuelBand, the ill-fated Jawbone Up and a refreshed line of Fitbit trackers. Now another product is arriving that promises to do basically the same thing -- namely, track your activity, sleep patterns and food intake using a wearable gadget and mobile app. That thing you see up there is called Larklife and for now, at least, it works exclusively with iOS devices. It's a splash-resistant (but not waterproof) band that has a pedometer inside, counting your steps throughout the day. It can also tell how long you sleep each night, as well as how long it takes you to nod off. There's even a vibrating alarm built into the band -- something we first saw on the Up earlier this year. (As it happens, Lark's earlier products were sleep aids, so the inclusion of this feature actually makes a lot of sense.) As for monitoring your dietary habits, Larklife doesn't automatically track your food intake, but the app does include a food diary where you can manually enter your meals.

Additionally, Larklife uses Bluetooth Smart to automatically sync with your iPhone so that you don't have to plug the band into a PC just to update your fitness stats. (The new Fitbit trackers work this way this too.) Additionally, the band uses a proprietary technology that can discern when you're running or walking, which means the app will log workouts even if you forget to enter them. The last intriguing bit is that the app dishes out smart, contextually aware advice. Didn't get much sleep last night? Larklife will remind you to eat more protein than usual at breakfast, so that you have enough energy to get you through the day. The app also rewards good behavior in the form of iOS notifications and colorful on-screen badges, though competing products admittedly take a very similar approach when it comes to keeping users motivated.

Larklife is up for pre-order starting today, and is priced at $150 -- a rather large premium over the new Fitbit One, which will sell for $100. As for precise availability, all we know is that retailers will start stocking Larklife "before the holidays." Whether that means Halloween, Thanksgiving or some gift-giving celebration will be revealed some other day.
