Product Description

The Mio Slice HRM Activity Tracker gives you access to the physiological impact your training is having on your body.

This is the first wearable fitness tracker to feature PAI (Personal Activity Intelligence). PAI is a new metric that tracks your body’s response to all your physical activity; not just your steps. This gives you the feedback you can use to improve the quality of your life.

Mio’s Slice fitness tracker also offers sleep tracking, calories burned, distance and more. All this from a super stylish, water-resistant wristband with a simple one-button operation.
