When it comes to devices for tracking fitness and health stats, smartwatches are the latest craze.

While wearable devices such as Fitbit Flex and Jawbone UP track your fitness and transmit data to your smartphone, this new breed of gadget doesn't require a phone but rather serves as a second screen, keeping all your data at the ready so you can focus on the task at hand: exercising.

While the much-hyped Apple iWatch is rumored to track fitness and health, here are a slew of new gadgets to keep an eye on. And with research firm ABI Research predicting that more than a million smartwatches will ship this year, expect more on the way.

Pebble: This Kickstarter success connects via Bluetooth to both Apple and Android phones to display incoming calls, texts, emails, etc., and has also picked fitness app Runkeeper as its first third-party app integration. Another Pebble app turns the watch into a cycling computer, reports tech website Mobihealthnews. Downside: the watch doesn't feature GPS so you'll still need to rely on your phone. Price is $150, with shipping scheduled for this summer.
