Used for general exercise, the Mio Fuse fitness tracker features patented electro-optical cell sensor technology to measure the volume of blood under the skin.

Algorithms are applied to detect the heart’s true rhythm during workouts, with a 0.99 correlation to EKG (electrocardiogram) in laboratory testing.

“With all-day activity tracking and strapless heart rate monitoring, users can get a more accurate record of how many calories they’ve burnt, how hard they’ve pushed themselves during workouts and how their body is responding with the Mio Fuse,” says Mio Global CEO Liz Dickinson.

Mio Fuse is water resistant to 30m and is compatible with a range of third party apps.
