The iPhone can even measure your heart rate without accessory: 3 apps tested on video

The iPhone surprises
always by its many possibilities, and if you are told that it is capable
to make measurements of your heart rate without any accessories
Additional you may not believe it. And yet it is the
case, ! Applications available on the free, free or sold app
less than one euro promise to performmeasurement of your frequency
heart, simply with the camera and your finger placed on the flash,
By analyzing the differences in colors.

For you, we swim in the middle of science fiction and it is completely not
possible ? So we wanted to take the test and compare the results of these
applications with a measurement made thanks to a cardio frequency meter
Classic, that used by athletes.

You will find three applications tested, the first is French, it
is namedHeart Fitness, the second isInstant Heart
Rateand the thirdPulse O Matic.

Here is the result of this test:

For each of these apps, we have done the video test and you will
be able to compare over time to measurement made thanks to
The iPhone with the measurement made thanks to the sensor placed on the tester's chest
and the watch that displays live pulsations:

As much to tell you right away, you willbe surprised,
The measurement is indeed of very good quality.

We arrive at the right result at a few pulsations near see even exactly to
same results at certain times. It's very amazing, high technology
Imaginative and we really like that!

The different applications tested are as follows, in order of appearance
In the video:

• 
  Heart Fitnessfree

• 
  Instant heart rate0,79 euros

• 
  Pulse o matic0,79 euros

In conclusion, it will be said that among the applications, Heart Fitness prevails
For two simple reasons: it works well and it is free. By
against, it is at the expense of the rather austere user interface, and the
presence of advertising.

Among the paid applications, Instant Heart misses the interface resolutely
Modern offers notes to save them for each measure. In
General It gives good quality results relatively quickly. On
the test above it was offset from a few pulsations but it is quite
rare. Finally pulse o matic, with a design resolutely similar to an oscilloscope,
Even if it has improved during the last update, offers everything to
even the results in general a little offbeat, and above all it is a little less
practice to use.

As for the speed of four applications, Instant Heart Rate is
The fastest but not instant as its name suggests, you have to wait
That the pulse be spotted, confirmed and ultimately measured. So you can
use this type of solution not during the effort of course but by
example the end of a jogging, just to give you an idea of ​​your
heart rate, then to see your time to
recovery.

Suddenly, this type of solution will never replace a belt or a
dedicated iPhone accessory, but it is incredible to realize that with the
flash and camera, your iPhone is able to measure your frequency
Heart with very good precision!

And forcontinuous measurements during the effort always with
l’iPhone, we hadtested

of measures, these are
