It's compatible with over 50 different apps, making it easy for you to add your run data to whatever calorie counter or activity tracker you are using. Best of all, it's surprisingly inexpensive!

What Reviewers Say:

  • Paired with my iPhone 5 immediately and works accurate with mobile apps, heart rate doesn't jump around like the first unit I purchased. I am impressed with the customer service provided by Mobile City.
  • This thing is awesome.
  • Love it! It connects to the apps I have on my phone.
    I used to have a heart rate monitor that connected to a watch and connected to the cardio machines at the gym.
