■ Training With Heart Rate Zones
Everybody has a different purpose for their training. Someone run for diet, someone ride for improving their cardio endurance. Exercising at the correct intensity can help you get the most out of your workouts.

This app shows you your exercise intensity using your real-time heart rate, and it has four heart rate zones to understand your exercise intensity at a glance.

• PEAK - for improving performance and speed.
• CARDIO - for improving cardio endurance.
• FAT BURN - For longer exercise. Predominantly uses fat for energy.
• WARM UP - For preparation and recovery.

With these four zones, you can start heart rate training very easily and quickly.
You don't have to remember your target heart rate or intensity %.

◎ Heart Rate and Exercise Intensity in real-time
• You can easily see which Heart Rate Zone you are in while exercise.
• Your Apple Watch taps you on the wrist when heart rate zone changes.

◎ Review your improvements with Recovery Heart Rate
Recovery Heart Rate is the difference between your exercising heart rate and your heart rate one minutes after the exercise has stopped.
It is a good indicator to gauge your fitness level!

Very useful breakdown of heart rate zone

Lives in Houston

I use this on combination with strava and Apple to get a much deeper level of understanding, analysis and detail on my effort and hart rate and aerobic zones. Data is taken in from my device and from strava and then analyzed. I don’t use zones to measure my activity.

The analysis is excellent and really useful to monitor my improvement and effort. I can see how much time I spend in each zone and where I put my effort. I have used this to stay in a specific zone to burn fat or improve endurance.

I bought the premium which gives even more detail and stats on how I’ve performed. I’m very useful stuff and if you like our data this app is very good. Basically I haven’t seen any other mainstream app go to the lengths this one does. If you’re training for any sort of event or are trying to just get better in performance this gives you a great insight to how you’re doing.

Woah it’s better than I thought


Woohoo it’s beautiful and that’s a great selling point for this app but what I like about it and what inspired me to write this review is this: this app will track and analyze your heart rate in workouts started with the Workouts app. I just tracked a workout in the Workouts app because that will give me achievements, but when I looked in the Zones app I found that workout there and it was graphed and told me how long I spent in each zone. The Zones app can also track many more types of workouts than the Workouts app (such as fishing, strength training, and even fun), although I’d recommend tracking your workouts with the Workouts app if it’s there so you can get the achievements.

Off to a bad start.


Froze up my watch 3 quarters through my first workout. I looked at my watch to see my heart rate and found it said that I was only at 73bpm when it should’ve been well over 120 could not get it to read my heart rate again until I shut down the watch. The watch took over 10 minutes to restart, then when I restarted the app not only had it lost app previous workout information when I clicked start it’s spent another 10 minutes with the screen that said starting. Once I finally killed the app and started it again it started to read. As you can imagine I was disappointed not to mention this was during fairly intense workout where I have little to no patience for interruptions. I will try it a few more times and I will update this review if things get better.
