There are lots of wearable activity trackers on the market, but most of them are wrist-based, which means they're not always as accurate as they could be (just look at the recent Fitbit controversy for proof). But Myzone's MZ-3 is different because it's strapped to your chest, either as a simple strap, as part of a compression vest or integrated into a sports bra.

The way more accurate and super versatile wearable can be used to track all kinds of activities, like running, swimming or just a session in the gym. It's different from similar devices because it isn't just focused on tracking your fitness, but instead wants to make staying active a fun and exciting game.

It does this by tracking what you get up to based on the effort you've put in, not what you've achieved. So at the start it calibrates both your personal body metrics with your maximum heart-rate and creates a fitness handicap that’s personal to you – hence the name Myzone. The more effort you put in the more the more Myzone Effort Points (or MEPs) you earn and because of your handicap all Myzone users compete on a level playing field.

The Myzone app then serves up a simple coloured tile with a real-time percentage rating in order to show you how much capacity of your maximum heart rate you're using at any given time. From there you score points the harder you work and work your way up the different tiles.

Not only is Myzone more accurate than similar devices because it's strapped to your chest, making heart-rate readings the best in the business. But it's also versatile and gamifies fitness tracking, allowing you to focus on earning points and putting in more effort than working to arbitrary goals.
