Myzone is the next big step in sports wearables, motivating you to get the most from exercise, whatever your fitness level, however you train. It lets you know how hard you’re trying when you work out and features a heart rate accuracy of over 99%. Myzone also offers amongst the most precise calorie-crunch data on the market, plus the ability to effectively calculate cardio and weight training.

Myzone uniquely rewards effort, while providing a game based platform and social experience that is both inclusive and engaging to all, regardless of athletic ability. As the name suggests, its technology creates bespoke and responsive targets for each individual, to provide personal feedback – hence ‘Myzone’.
Creating a personal handicap based on your maximum heart rate, it is possible to beat an elite athlete by simply working harder. For example, you might finish behind an elite athlete in an endurance run, but exert greater effort and Myzone makes you the winner – so everyone competes on a level playing field.

Myzone encourages competition with other users through cloud-based challenges via a web-based account and bespoke app. The community aspect of Myzone makes it a Facebook for physical activity. Users can analyze, ‘like’, and comment on each other’s workouts, while the app logs your activity history and even updates you over email. In fact, this is the only system to recognize and notify you when you have attained the World Health Organization’s recommended guidelines for physical activity.
The Myzone App allows you to sync your Myzone MZ-3 Physical Activity Belt with your phone meaning you can now see live data and upload stored workouts on your phone. If you prefer to use your MZ-3 with third party fitness apps then your data will still be stored (up to 16 hours) until you sync with your Myzone® app. 

This app integrates with many other platforms, including Apple Health. If you grant permission, we will save your activity calories, height, weight, BMI, BMR and body fat data to Apple Health.

**** Please note that the app will only work if you have a Myzone® Account (you can create an account in the app for free if you don’t have one already) and your tile will only be shown and data uploaded if you have the new Myzone® MZ-3 Physical Activity Belt.”

Love the app but a couple of issues remain

I love this app as it has really helped me to push myself during every workout to make the most out of my training. I really like being able to participate in challenges with other people as well as encourage them through liking their workouts. I also find the MyZone match sessions brilliant for when I am at the gym but do not have the inspiration (particularly early in the morning) to think of a workout to do. It stops me from getting bored on a machine as I am looking to reach the next stage of the match rather than the time remaining!

The issues that I would love MyZone to fix are:
1. 80% - 89% writing being white on a yellow background. Quite difficult to read when you are jumping around doing exercise and your eyes aren’t focussed!
2. The belt is great but the black part has started to occasionally cut into me leaving scars which I have to pad (for protection) before each workout until they heal again. I know a few others who have had the same problem and they have a similar build to me, slim waist and therefore have to have the belt on the tightest setting it can go, which could be a contributing factor as the belt perhaps isn’t fitting as well as it could on us. I would welcome some feedback on this if possible!

Please sort messaging real time

Honestly, the concept of myzone and the app is great. But something has been lost in the execution. Specifically on the messaging function of the app - (1) the messaging function needs work. It is hideously slow (can be 4mins between posting a comment and it appearing to others), which interrupts real time chat across a group; (2) there is a limit to the text length in chats, which is not messages disappear; and (3) you can’t post a picture with comments....the two actions are distinct.

This app could be brilliant. But it’s not. The belts are also flaky and break, although our gym is good at replacing them. The shame of it all is that this app could be EPIC for motivation, for community and for people feeling that fitness is a happy part of their lives. The HR monitor is useful to motivate yourself just on your own, but if you are part of a group, you can set up challenges on the app and motivate each other. This is fantastic and I myself have an absolutely stellar group on this app. We motivate each other and we have all seen our engagement at the gym increase. has been suggested we move to WhatsApp for chat, due to the items above - in particular the time lag, which is a real pain in a large and active group as the message sequencing is all over the place. I think that’s a shame for something probably easily fixed.... developers, what do you think?

Hi, thanks for the feedback! We have taken steps to ensure that MZChat messages are received faster, and we plan on making the 750 character limit clearer in a future release.

Really enjoying the app. The targets and the challenges motivate me to do the 'fizz' which I normally struggle to raise any enthusiasm for. The points you get are awarded for your effort based on your heart rate, so this really levels the playing field both from your current fitness level and gender. I have had no problems with the belt or linking it to my phone. The app is pretty simple to use and in workout mode displays the basic info you need HR, Calories burned, your MEPS (how much effort you have expended on the workout so far), the HR monitor battery life. For me the best bit is the coloured zones that are displayed, to show you what % of your max heart rate you are working at, so that you can control your exercise and importantly ensure you do not over stretch yourself unhealthy. If there was a minor downside, it would be that for older bods with less than perfect eyesight, the white letters on the Yellow background (80%+ workrate zone) really don't standout too well and really could do with being black or a better contrasting colour. All in all an excellent bit of kit, which if you want a motivational way of staying healthy fits the bill.
