The $129.95 Alta is the first wrist-worn fitness tracker from Fitbit that doesn't really look like a Fitbit (save for the new watch-like Blaze ($142.95 at Amazon UK)(Opens in a new window) ). It's sleek, slim, and has a modular design that can be changed to match your outfit each day. Think of it as the new, fashion-forward Fitbit Charge ($142.95 at Amazon UK)(Opens in a new window) . It tracks many of the same stats as the Charge, including your active minutes, distance, calories, sleep, and steps. And it goes even further, with idle alerts and text notifications from your smartphone. But the Alta lacks an altimeter, GPS, or heart rate monitor, which means athletes who need more advanced features are better off checking out one of Fitbit's other trackers, like the Charge HR ($142.95 at Amazon UK)(Opens in a new window) or the Surge ($142.95 at Amazon UK)(Opens in a new window) .  Design and Display The Fitbit Alta ($142.95 at Amazon UK)(Opens in a new window)  tries its best to ...

The Alta is Fitbit's sleekest, slimmest fitness tracker yet, but if you don't care about looks you can get more functionality for nearly the same price.

Slim design; Swappable bands; Accurate fitness stats; Delivers idle alerts and smartphone notifications

Sometimes unresponsive; Display is tough to see in direct sunlight; No heart rate monitoring, GPS, or stair climbing; Not waterproof

A Fitbit, for better or worse, looks like a Fitbit. For the past seven years Fitbit's product design has skewed toy-like, friendly, utilitarian. A Fitbit won't be mistaken for jewelry; it's not high-fashion, though it may try ; it's a Fitbit.

More fashionable Fitbit; Auto-tracks exercise and sleep; Week-long battery life

Tap-screen display; No heart-rate sensors; No software leaps since 2015

Don't expect to earn too many style points with the $130 Fitbit Alta, and you won't be disappointed. The fitness tracker is good as an everyday accessory for those with smaller wrists, and accurately monitors your activity.

Slim design with interchangeable bands; Accurate; automatic sleep tracking; Easy-to-use app

Finicky "touch" screen

You can spot a Fitbit from across the room. The Fitbit Charge HR and Surge, the company's two most popular trackers, aren't exactly jewerly, and I would never be caught wearing one to a wedding or another formal event. But Fitbit is changing.

While ultimately a more stylish (but heart-rate free) version of the older Charge HR, the Fitbit Alta is a winning fitness tracker with solid style appeal.

The Fitbit Alta is a stylish fitness tracker with swappable bands, basic phone notifications and week-long battery life; The new "Move" alerts bring something new; Fitbit's software is still one of our favorites, and has the largest social base as well.

There's no heart-rate sensor, and it can't be worn in the shower; The tracker is expensive for what it can do and so are the accessory straps; The display is difficult to see outdoors and is susceptible to scratches, and notifications are hard to read.

If you're looking for an attractive, affordable fitness tracker that can handle the basics with little to no problems at all, you should consider the Fitbit Alta. Hardcore gym rats should look elsewhere.

- Sleek; modern design - Silicone strap is very comfortable - 5-day battery life - Accurate step and sleep tracking - Affordable price point - Companion app is easy to use

- Interchangeable bands are pricey - Silicone band can be difficult to put on - No waterproofing - Charging cable is short and awkward to use

I used my new Alta about 2 1/2 weeks now. I love it, it does everything that I need. I love the design and my purple band, plus the fact that I can change it if I choose to. One of the best features is that it keeps me moving every hour by encouraging me to take 250 steps.

Fitbit Alta does not offer much new in terms of functionalities, compared to the older Fitbit products. It does not have a built-in GPS and a heart rate sensor too. What it does offer, however, is a sleeker, slimmer, and adaptive design for those who are fashion-conscious.

Fitbit makes good fitness trackers, but so does everybody these days .You can buy an AUD$20 fitness band from Xiaomi and it will count your steps with a reasonable degree of accuracy, or you can buy a AUD$500 Apple Watch and it will also count your steps with a reasonable degree of accuracy.
