Now everything counts

Capture the intensity of every activity with Mio SLICE, the first activity tracker to feature PAI.
A revolutionary new system that turns the only number that matters—your heart rate—into a single, personal score, showing you how much activity you need to stay healthy.

What is PAI?
PAI is Personal Activity Intelligence. Rather than just using steps, PAI’s revolutionary algorithm makes sense of your personal heart rate data, giving you a simple number that shows how much activity you need to live a longer, healthier life.

Backed by science.
Dr. Wisloff – a pioneer in health and exercise research, created the PAI system from the HUNT study, one of the world’s largest health studies involving more than 45,000 people over 25 years. From its research, he was able to show how much exercise people personally needed to stay healthy.

By focusing on quality exercise, such as moderate-to-high intensity exercise, he found that people who kept their PAI score above 100 were more likely to live longer and stay healthier.

Track it all. Not just steps.
PAI analyzes every movement you make, including activities like spinning, yoga, even gardening.

Move with meaning.
PAI tracks your heart rate intensity and shows which activities earned the most PAI points in your day so you can make better lifestyle choices.

One simple goal.
All you need is one number – your PAI score. Keep it above 100 over a 7-day rolling window to know you’re staying healthy, even if you work harder on some days, and less on others.

Personalized to you.
No matter what your fitness level is, PAI shows you what intensity level you need to be in to improve.

Warranty information

MIO was created in 1999 by Liz Dickinson.

They believe that with a little assistance and motivation everyone can achieve a healthy lifestyle and their fitness goals. Their aim is to provide with the finest health and fitness technologies to help customers hit their target in a safe and enjoyable way. .

After listening carefully to performance athletes, MIO created what they needed: a a strapless heart rate monitor sports watch. For over a decade, Liz has made it her mission to find "The Holy Grail" of heart rate monitors; a watch that displays continuous heart rate without finger sensors and without a chest strap that is accurate even at performance running speeds. Her journey lead her to Philips Electronics in the Netherlands. They showed her a promising technology that with the help of her own small but brilliant design and engineering team , MIO could finally crack the code and deliver the ultimate heart rate monitor for the performance athlete: the Alpha.
