Heart Rate

An easy-to-use app that measures your heart rate

This easy-to-use app helps you measure accurately your heart rate . Tracking your heart rate can be a great way to monitor your heart health and the secret to getting fit. The measurement process is very simple, you are only asked to touch with your index finger the phone's built-in rear camera. Every time your heart beats, the amount of blood that reaches the capillaries in your finger swells and then recedes; because blood absorbs light, our app is able to capture this flow by using the flash of your phone's camera to illuminate the skin and create a reflection.

How to get accurate BPM readings

1 - Gently place your index finger on the lens of the phone's rear camera and hold it as still as possible.

2 - Rotate the finger to fully cover the LED flash but avoid touching it, as it can get very hot when is turned on.

3 - Tap the START button and wait 10 seconds, then read the final BPM value.

4 - This heart rate is accurate within the ACC percentage. In case the dispersion exceeds 10 percent, shift your finger a little and repeat the whole process. The waveform must be uniform, having a regular pattern, as in the figure above.

Normal heart rates

Children (ages 6 - 15, at rest) 70 - 100 beats per minute

Adults (age 18 and over, at rest) 60 - 100 beats per minute

Keep in mind that many factors can influence heart rate, including:

- Age, fitness and activity levels

- Being a smoker, having cardiovascular disease, high cholesterol or diabetes

- Air temperature, body position (standing up or lying down, for example)

- Emotions, body size, medications

Disclaimer

1. Talk with your doctor about whether it is necessary for you to measure your heart rate regularly. Heart rate is only one part of the puzzle of total heart health and fitness.

2. Talk to your doctor if you think you detect:

- a very low pulse rate (under 60, or under 40-50 if you're very active) at rest

- a very high pulse rate (over 100) at rest or an irregular pulse.

3. Don't rely on the displayed heart rate as an indicator of your heart health, use a dedicated medical device.

4. Don't make changes to your heart medication based on the heart rate readings from the app.
