Alternative uses you can give your Android: heart rate meter

Some companies include a sensor in their terminals that measures the heart rate that they have, such as Samsung in their most powerful devices. Furthermore, the vast majority of smartwatch with Android Wear have this integrated accessory. But, it is possible that you do not have a device that includes this component, something that can be remedied to some extent with some applications.

Being able to measure the heart rate that is normal or at the end of a sport practice It is of interest to you since it allows you to know the physical state in a quite concrete way and, also, if there are advances in this section. The point is that if you have the appropriate software, it is possible to know data with adequate precision with Android terminals that do not integrate a specific accessory.

For this, the set of the rear camera that is installed is used (the flash also has a lot to say in some cases). But, yes, it is necessary to have the suitable applications to be able to carry out the measurement action -the reflection of a light- to achieve the results that allow an approximate knowledge of the heart rate. Obviously, the precision is not the same as that of a device created to carry out this work, but as a guideline the one obtained is valid.

The developments we recommend

There are quite a few in the app store Play Store from Google, but we have chosen three that we consider to be the best that there are currently that offer a simple and appropriate use. Without further ado, and by providing the download link in each of them, we will now indicate the jobs:

Runtastic Heart Rate

This application is endorsed by the company that develops it, and with it it is possible to know the heart rate you have just by using the rear camera of your Android terminal. The data obtained are analyzed and even comparative reports are offered. It is possible to take different measurements depending on the moment in question, such as at rest or before or after doing sports.

Cardiograph

With a name that is not at all flashy (and much less intuitive), this application offers everything you need to know your heart rate at any time with an Android terminal. It allows the creation of profiles for different users and the results are displayed in the form of analysis. Its use requires the rear camera and the interface is tremendously clear, so there are no problems when using this development.

Instant Heart Rate

Simple and fast, it allows you to know the heart rate by covering the rear chamber of the Android terminal with your finger (but without pressing too much, something that is advisable not to do with these types of applications, since it reduces blood flow and therefore the results are not are very reliable). Lets carry a measurement history and it has an informative scale so that you know if the results are adequate. A highly recommended option despite not being translated.
