Also of note is the sleep tracking, because this has been a feature of Fitbit since practically the beginning, and the company has changed some things this time, with no button presses required to get you in the mode to sleep.

That’s something pretty much every other fitness band forces you to do, and in testing competing products, we’ve certainly missed out on sleep tracked nights due to just simply forgetting to do this one step.

In the new Fitbit devices, though, it will work out when you’re sleeping, tracking you accordingly and providing a more solid representation of your sleeping patterns.

If you need something that goes even more in-depth, there will be the Fitbit Charge HR, a slight deviation of the Charge that won’t be on store shelves until early next year, but will bring all the features of the Charge and throw in a heart rate monitor as well.

This feature looks to work in a similar capacity to the green light optical heart rate tracking of the Samsung Galaxy S5, but will be working all the time, rather than just when you switch it on.

As a result of this constant heart rate analysis, the battery life of the Fitbit Charge HR will drop to five days of constant use before needing a charge, but will provide an even more complete analysis of your health.

Finally, there will be the Surge, a product with more sensor technology relying on eight sensors, with three axis accelerometers, a gyroscope, compass, light sensor, altimeter, heart rate tracker, and even a GPS.

The Fitbit Surge also looks to be the company’s first fitness wearable designed more like a watch, offering multiple faces for people who want a fashionable watch, but bringing a monochromatic touchscreen to the table with just enough technology to keep it interactive and friendly, while also providing almost a week’s worth of battery life provided the GPS isn’t used all the time.

If it is and you’re going for a run, Fitbit tells us there will be around five hours of battery life, with information collaborated on steps, calories, distance, heart rate, and a map made of everything you’re doing.

We’re also told that the straps and wrist bands have been considered completely in this generation, with dermatologists consulted to make a wearable that won’t irritate the skin of anyone wearing the products.

Assisting the technology is the app, which Fitbit has improved so that people with friends online will be able to compete more, turning the idea of exercising alone into something more akin to that of a game, a process many know as “gamification.”
