Sensors
play an important role in our smartphones, for example, when you bring the
phone close to your ears during a call, the screen is automatically turned off
via the proximity sensor in order to prevent wrong touching on the screen.
Smartphones also include many other sensors such as the fingerprint sensor,
accelerometer, gyroscope, compass, etc. Among other sensors, many very cool
applications have been developed that take advantage of these sensors to
achieve certain functions such as measuring heart rate, knowing the speed of
movement, ground height, and other things. Here are the best of these
applications that you can download on your phone for free.
Sensors
Toolbox is a great application that offers you the function of testing the phone
sensors to make sure that they are working well without any problem, so it is a
very useful application in case you are buying a used phone and you can use it
to perform tests for your current phone also to make sure that it is working
well, and this application includes sensors Many such as sensors for camera,
gyroscope, auto-rotate, GPS sensor, microphone, pedometer, light sensor,
temperature sensor (if you have one in your phone) and much more.
This
application helps you to check the altitude levels above the ground using your
phone and therefore it is very useful in the case of traveling especially, the
Altimeter application relies on the Global Positioning System (GPS) to provide
accurate readings about the altitude above sea level anywhere and any time, but
the most important thing about this program is that it works offline and even
while in flight mode. The application also allows you to save the altitudes of
your favorite locations and contains multiple units of measurement such as
meters and feet that you can easily switch between them.
GPS
Speedometer application helps you to measure the speed of movement using your
phone in real time, and therefore you can use it inside the car, for example,
bus or motorcycle to know the speed of movement and you can use it while
running as well, and this application also shows you a lot of useful data such
as distance traveled and speed The application also allows you to add a panel
on the home screen of the phone to display the speed at any time and this
application works based on the GPS system available in smart phones.
As the
name of the app suggests, it is a compass for directions, latitude and
longitude, but it provides you with a lot of other very useful features
including knowing the distance, direction and altitude level and it also allows
you to explore famous places like cities, attractions, etc. The phone’s
magnetism, GPS and some other sensors, so it gives very accurate results and
also shows you how to set the compass correctly in the phone to ensure the
accuracy of the results.
Another
very special application that works through the phone’s camera and the function
of this application is to measure the heart rate per minute, as all you have to
do is put your finger over the camera and the application will turn on the
flash and then analyze the color of the fingers, and this application provides
many very great features Including that it is completely free without the need
to purchase paid features (for Android) and it also allows you to create more
than one profile in order to track the heart rate of more than one person, and
it also saves the measurement history for viewing at any time.
