The Runtastic Running app is indeed quite good, if everything would work as it should. On the hardware side is Runtastic a disaster because of this chest is no exception. In the 9 months, where he worked, to the start of training completely nonsensical pulse values were usually displayed (z. B. shortly after loose Lost Ravens 20 heartbeats on maximum frequency) or pulse indicator fell from and to the same completely. A mystery has always been after the run on the phone displayed heart rate curve and that appears on the same drive on the website of runtastic. Plausible at first glance, an interval workout just looks so, as you would expect for an interval workout. But if one compares the heart rate curve on the phone with the on the web site in more detail, it is observed that both curves look similar only. However, the curves are not congruent, as one would expect for the the same run yes, but in some cases totally different. I always crowded on the suspicion that missing data points were calculated due to Brustgurtaussetzern randomly. After 9 months then came the catastrophic failure of the chest strap. Batteries were fine, because it can not lie. Perhaps it is at around 20 connection attempts time to connect to the phone about, but which then breaks off again and after a few seconds. Based on my previous experience with Runtastic I can only say: hands off Runtastic products. No wonder Runtastic disabled public clouds help forum some time ago, because there anwuchsen complaints massively.
