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.”

Try it for yourself... not because of someone else

I decided over almost 2 years ago to buy the heart monitor because my gym was selling it and because people were getting a better work out from actively tracking their HR DURING their workout, not after. Yeah there’s a small lag time, but it’s so small by the time I look up I know where I am and what I need to do. Fast forward and I’m not at my gym now but completely understand my zones and where I need to be for what I want to accomplish. My Ymca is using this as their monitor and even though I don’t go often to the Y I feel good knowing I have it. I bought a Peloton bike a few months ago, who uses their own HR monitor they sell, but I trust myZone so much now I just love to stick with it. It’s easy, still have my friends from
My old gym and the Y and it syncs with my Fitbit well. So yeah it has a little lag time but by the time I take it off, undress for the shower and hop out it asks me if I wanna name my workout. Sure I can do that now. I don’t need to do it in an instant. It’s all in your own perspective. Oh and 2 years ago I bought mine... it just now got to 55% and I’ve NEVER charged it... ever. I love MyZone.

Great incentive to get to the gym!!!

I love seeing my info on the screen as soon as I enter a group fitness class. The color-coded monitor shows heart rate as a percent, and I find myself continuously moving just to keep myself in the blue (60%) status or above. The MEP point system is perfect for goal setting. I enjoy naming each saved workout and adding a picture behind the bar graph data table.
When the monitors are off, the wearable device requires the phone nearby with app open and logging in order to retain workout data. I lost an entire workout because I left my phone behind and there were no active screens on that day. I would like to be able to return home from a workout or return to the gym the next time the displays are active and sync up recent workouts or movements. I thought the device would have some memory for the $99 cost.
Another nice feature would be the ability to truncate the timeline of your saved bar graphs. One day I had worn the device while driving to and from the gym. The device had logged ALL data with the device worn, including the non-workout times. Contrary to what I said in the earlier paragraph, the phone was in range, but with the app closed, not actively displaying data.
Finally, I’d like to edit more than just a title and photo. Maybe add ability edit / delete the comments?

Lost Data. Extremely buggy.

I’ve been having problems lately where the MyZone app fails to load historical data off the belt. I don’t typically work out near a MyZone receiver or with the belt streaming to the app on my iPhone. I know for a fact the belt is recording HR because it displays on the gym equipment. I used to do my workout (out of phone range) then open up the app on my phone before taking the belt off and it would load my workout data. That doesn’t work any more. Now the only data that gets saved in the app is for the period I am within range of the phone. The actual workout data never gets imported off the belt. I used to get around this by installing the app on an iPad and use it to load the data hours after the workout. It took a few tries sometimes but it usually worked. Fed up with the app I tried streaming to my Apple Watch. Today when I went to upload data from my watch it showed there were nearly 300 samples. It hit “upload” and got confirmation that upload was successful. The data is not in the app on my IPhone. The workout data is just gone. It appears that if the belt is streaming data over Bluetooth that it doesn’t save data to its internal memory so it can’t be imported later. I never had problems before they added Apple Watch suppprt. I am use the most updated versions of everything. If I keep having problems I’m going to quit using it because it isn’t worth the hassle.
