### 5/5 — Simple and Effective

*2026-01-23*

Finally an excellent app that includes resting heart rate when considering fitness.  This app is excellent!

### 1/5 — Silly/Waste

*2023-11-10*

An app to look up heart rate zones by age. That’s silly as you’d use that app exactly ONCE in your life and can easily look up the information online. Unless I suppose you are a trainer who looks up other people’s zingers all day long…

### 5/5 — Great time saver!

*2023-09-25*

Super quick and easy way to know where you need to be operating to get the most out of your workouts.

### 5/5 — Great resource

*2023-07-19*

I have this chart open while I work out and keep track of my heart rate levels .

### 5/5 — Useful

*2021-08-11*

I’ve found this app to be a useful point of reference. However, the HR measurements on the other apps I use score lower rates than this app. I’m left wondering about the “how” and “why” of the differences.

### 5/5 — Finally a good clean informative app!

*2019-02-07, version 1.0.0*

Input your 2 pieces of info (age and resting heart rate) and an instant no bs answer! Right to the point- no overwhelming information. 

There needs to be a lot more apps like this! Perfect for the beginner like me.

Thank you.

### 5/5 — Great Tool

Great tool for quickly and easily finding my heart rate zones. I am using it to for running.

### 4/5 — Basic app that helps me with heart rate zones

*2016-08-21*

My clients can download this and keep it with them to learn where their zones are for fat vs cardio and when to push through.

### 5/5 — An app that does all the THR calculation work for you

*2016-04-20*

This app is great as it does all the work for you calculations for you.   Although I use a separate spreadsheet to calculate where I want to train at, I do find this very handy to do a quick peak to remind me my HR target zones.

### 5/5 — Like it!

*2015-08-19*

This app is a great time saver to be able to calculate karvonen heart rate training zones. There is also a lot of useful information in the app. 

I have one small request..in my NASM book they go with 3 training zones: 65-75%, 76-85%, 86-95%. I'd like to see a setting option to make these the displayed zones because I will train clients based on these three zones! 

Thanks for saving me the time of making this app ;)
