Heart rates were traditionally recorded using external hardware like sensors, cardiac monitors, chest straps, or counting pulses at the wrist in the olden times. Today’s smartphones, on the other hand, eliminate the need for heavy machinery or calculations.
When your heart beats, the volume of blood flowing through your fingertip changes. A heart rate monitoring app can detect this by capturing color changes in your fingertip with the camera on your phone. The heart rate is calculated using proprietary methods.
Let’s dig into how you can monitor your heart rate using a heart rate monitoring app.
What exactly do you mean when you say “heart rate”?
The amount of times your heart beats in a minute is known as your heart rate. The average heart rate of most healthy adults is between 60 and 100 beats per minute. When we are active, our hearts beat quicker to send more blood to our muscles, which raises our heart rate. During moments of stress, worry, or excitement, your heart rate will also rise. And, as you might expect, our hearts beat more slowly when we are relaxed.
What is a heart rate monitoring app?
While a smartwatch, heart rate device, and fitness tracker can monitor your heart rate, you can now also use an app to check heart rate.
When utilizing one of these iOS, Android, or Windows apps, no additional hardware is necessary because it uses its built-in camera and lighting to detect a heartbeat by scanning the user’s finger or face and measuring blood flow. It may seem unusual, but it works and is reasonably accurate for estimating your average heart rate.
These apps can track your heart rate in a variety of ways.
Apps on your phone can measure your heart rate by detecting changes in blood volume beneath the skin’s surface, similar to the heart rate trackers built into most fitness wearables. It is known as photoplethysmography.
The way it works is that the volume of blood that enters the capillaries in your fingers and face swells and then recedes with each heartbeat. Because blood absorbs light, apps that use the flash of
your phone’s camera to highlight the skin and produce a reflection can capture this ebb and flow.
How reliable are these heart-rate monitor apps?
Although photoplethysmography is a tried-and-tested technique, not all heart rate monitoring applications employ the same approach.
Researchers have proven that the heart rate readings provided by several apps were inaccurate by more than 20 beats per minute in over 20% of observations compared to clinical gold standard measurements (ECG and fingertip pulse oximetry).
Although it’s not unexpected that heart rate apps don’t always function (and clinical-grade equipment most, if not all, advise against medical use), there were some winners and losers even within the apps.
Applications that require you to touch your finger to your phone’s built-in camera are more accurate, according to the study, than apps that ask you to hold your phone’s camera up to your face.
Although you must take app readings with a grain of salt, smartphone applications are unreliable if you are looking for an accurate overview of your heart rate over time.
