Those practising fitness or light/moderate sport activity might be interested in using a more generic device like the smartphone for casual readings of the heart rate, with some expected guarantee of reliability. While some recent GPS watches exploit the reflectance pulse oximetry principle, their usual target is dedicated sports people. 5 On healthy adults, results are more encouraging, possibly due to a better compliance and also finger size. For example, in children, it seems that they are not sufficiently precise. 3, 4įew independent studies also appeared that evaluated the effectiveness of such apps. 2 however, a number of mobile applications are nowadays available, some of which are also described in scientific literature. The first implementation on smartphone, using its camera and flash, has been described by Pelegris et al. Recently, a number of mobile applications (apps) appeared that allow for heart rate measurements basing on the photoplethysmography principle 1: they measure the changing absorbance of blood inside human tissue during the heartbeat cycle. The results suggest that heart rate apps might be used for measuring heart rate for fitness aims for many individuals, but further research is needed to i) analyse influence of smartphone features ii) identify personal factors hindering measurements and iii) verify reliability on different measurement sites. As gold standard, heart rate has been measured with a traditional heart rate monitor. The present study aims at adding up evidence in particular during physical activity, by comparing three apps on two different platforms (IOs and Android), on a broad range of heart rates. Some studies appeared on the reliability of some of those apps, with heterogeneous results. In fact, almost every smartphone now has a camera with flash that could be used for that. Some future features in the app that would be interesting, if the device can do it, would be HRV statistics and download of data for time between pulses (CSV file) for recordings of six or eight hours for my own analysis.Recently, a number of smartphone apps appeared that allow for heart rate measurements basing on the photoplethysmography principle. The chart could use more gridlines for better readability but is clear and can be saved or emailed (like a screenshot). I believe this tracker provides a more accurate measurement than any wrist-worn tracker unless the wrist tracker is extremely tight to the wrist.įor the ECG, you'd probably want to buy some guide to what ECGs should and typically look like otherwise you might see a different pulse but not know what it means, or is just normal variation anyway. Tip - brush the chest hairs out of the way first when putting them on!. As long as you sweat a bit, they're not difficult to pull off again. The adhesive patches almost never lose contact and you don't really feel them. The chest strap is comfortable but if you move a lot it sometimes briefly loses contact. If you want an accurate record of heartrate while exercising or through a day, or want to take some ECG measurements, this monitor works well. Checkme™ O2 72-Hour Wrist Oxygen Monitor.
