Fitbit officially unveiled its latest lineup of wrist-based wearable fitness trackers on Monday. We’ve already seen the new devices leak out a few times in the past month, but today we’re getting an official look the Fitbit Surge, the Fitbit Charge and the Fitbit Charge HR.

The Fitbit Charge is the least exciting of the company’s new lineup, but it’s also the only one available today. The Charge is basically a refreshed version of the Fitbit Force, which was recalled earlier this year following reports of skin irritation. Starting at $129, it offers the same basic experience, tracking your steps, distance and calories burned with instant stats. It also features a small OLED screen for displaying that information along with incoming calls and promises a week of battery life.

Next up is the Charge HR, which adds a built-in heart rate monitor and launches early next year. For $149, it features Fitbit’s own heart-rate tracking technology, using LED lights to measure your heart rate from your wrist. It’s unclear how well the heart rate monitor will actually work, though Fitbit claims it’s meant to be used mid-workout, which means you probably won’t need to sit still, as is the case from some other devices on the market. It also offers 5 days of battery life.

Finally there’s the Fitbit Surge, a self-proclaimed “Super Watch” also set to launch in early 2015. The Surge offers the same heart rate monitor along with built-in GPS, 3-axis accelerometers, a gyroscope, a compass, an altimeter and more. It packs a full-sized black-and-white touchscreen display, with SMS notifications, music controls and customizable watch faces.  Despite all of those functions, it also promises a full 7 days of battery life.

There’s a lot to be excited about, particularly when the Charge HR and Surge hit the market early next year. In the meantime, check out the video below and stay tuned for more on the Fitbit Charge as soon as we get our hands on the new device.
