Wearables company Fitbit announced three new devices, including what it described as a ‘fitness super watch’ which moves it on (slightly) from its exercise tracker niche.

It described Fitbit Charge as “Fitbit Force reinvented” – a bold claim bearing in mind that Force was subject to a voluntary recall after reports of skin irritation from “a small percentage of users”.

Features include monitoring of steps taken, distance traveled, calories burned and floors climbed, as well as including an OLED screen, caller ID when paired with a smartphone, water resistant design and 7-day battery life.

Charge HR targets more dedicated users, and includes continuous heart rate monitoring. LED lights are used to detect blood volume changes.

Fitbit Surge has a larger screen and offers “smartwatch features” such as caller ID, text alerts and mobile music control. It has eight sensors – GPS, 3-axis accelerometers, 3-axis gyroscope, digital compass, optical heart rate monitor, altimeter, ambient light sensor and touch screen.

Fitbit Charge is available now priced at $129.95, while Charge HR ($149.95) and Surge ($249.95) will be available early next year.
