Instead of showing your steps and other information, it monitors your activity in a more passive way so it can offer tips and advice for living a healthier lifestyle, sleeping better and being nicer to everyone around you.
That last part is one of the stranger features: two built-in microphones listen to your voice throughout the day and tell you how you sounded. You might have thought your tone was affectionate but the app could reveal you actually sounded bored. (You can turn off the mics whenever you want, though.)
It’s water resistant so you can swim with it and it will automatically track and identify activities such as walking, running, swimming and more.
Its regular price is $99.99, but has an introductory discount which knocks 35% off, making it only $64.99.
It comes in three colours: Black band with Onyx sensor capsule, Blush with Rose and Winter with Silver. As you’d expect, you can buy additional bands, which are initially available in six colours for $19.99 each ($15.99 for Early Access customers).
To use most of the features you’ll have to subscribe, which costs $3.99 per month (but you get six months free). That gets you access to everything over and above steps, sleep tracking and heart rate.
There will be various promotions from WW including options to get a free Halo band when you sign up for a WW membership.
