It is important to monitor your heart rate, especially when working out. Most people focus on calories and weight without considering their heart rate to determine how much energy they use per session. Heart rate monitor apps help you to know how fast your heart is beating, and whether you are working out at the right intensity.

Here are the best heart rate apps you can use on Android and iOS smartphones for your next workout session.

1. Instant Heart Rate

The Instant Heart Rate app starts with clear instructions on using the app to track your heart rate. By placing your finger gently on the camera lens, it can start detecting your pulse.

The stats are immediately displayed after it finishes detecting your heart rate. With age and gender details, they can better calibrate your beats per minute. Whether you want to manage your stress or live a healthy lifestyle, this app will show you how your heart is progressing to achieve your goals.

Instant Heart Rate also offers a library of educational health articles for users with diabetes.

You can change your training time zone from the default to rest zone, cardio zone, or fat burn zone, among others. This helps to get a more accurate measurement. Statistics are also available to keep track of your heart rate over time.

Quickly Monitor Your Heart Rate When Training
