Getting to 10,000 steps a day has long been a get fit mantra but whether or not it actually works is still up for debate.
At CES 2016, Mio Global, known for its optical heart rate monitoring tech, has revealed its new $99 Slice fitness tracker, which is aiming to give you a more accurate idea of your exertion each day.

There isn't much info yet on the activity band which tracks steps (yes), distance and calories burned. It comes in a range of colours, has a vibrating alarm and features a display to show the time and smartphone notifications. We don't have an actual release date yet but the Slice will arrive later in 2016.
Mio Slice: PAI score explained
What we do know is that it will be the first device to use Mio's Personal Activity Intelligence (PAI) score to motivate users. This is based on age, gender, resting heart rate and maximum heart rate so unsurprisingly it looks like Mio is keeping the focus on heart rate tracking here.
It's calculated on a rolling seven day score of your heart rate intensity and the aim is to keep it above 100.
It is designed to really show how hard you have worked your body, whether you've been sedentary or really pushed yourself, not simply just present you with the number of steps you've taken.
Mio's algorithms are based on a long term health study called the HUNT study which found that resting heart rates can predict cardiovascular health. It also found that keeping your PAI score above 100 could add up to 10 years onto your lifespan plus help to protect you from lifestyle diseases.
""PAI is the most relevant index for measuring whether your activity level is sufficient to achieve maximum health benefits," said Ulrik Wisløff, professor at the faculty of medicine, Norwegian University of Science and Technology. "Managing your PAI score helps you to reduce your risk of lifestyle-related diseases. Put simply, it helps you live healthier for longer."
In 2015, Mio Global teamed up with Philips and Beneufit to help patients with Parkinson's diseases with Fuse devices so it's clear Liz Dickinson and her company are thinking big in terms of what fitness trackers are capable of.
This is a really promising collaboration between real science and an easy to understand daily score that you can build into your routine. We're out at CES in Vegas so we'll bring you hands on first impressions with the Slice later this week. We will also update this story when we get more specs, battery life etc.
