Helped improve my workouts!

Heart Rate Ninja has transformed my workouts! No more guessing when I am doing cardio and strength exercises. Now I know when I need to push harder and when to slow it down. This app is easy to use and tracks my heart rate accurately (I use a Bluetooth Armband Heart Rate Monitor). I love all of the features and the challenge every 3 months to reach the black mask by accumulating points each session. It even sends you an email after each session with a breakdown of your workout, Heart Rate Ninja is Amazing!

Best Group Training App for Gym!

I have tried several different Group Heart Rate Monitoring Apps for my Gym and Heart Rate Ninja offers the most value at the lowest price. The app has numerous challenge and competition features that make working out fun for my clients. It has also increased my retention rates and increased my revenue by 20% within the first year of using Heart Rate Ninja! I am so glad we found Heart Rate Ninja it truly has changed the dynamic of my gym and helps keep us on top of our competition!

Everyone/ Every gym needs this app!

I’ve been to many gyms that use other heart rate systems but this is by far the best one I’ve used! There are so many cool features & it genuinely keeps you motivated and engaged! Added bonus on top of everything else, my Myzone monitor works perfectly with this system!! If I could rate this app more then 5 stars I would!
