ANT plus Please add ANT+ support. I'm pretty sure all ANT+ heart rate monitors have R-R, as that field is not optional. ANT+ doesn't pair, so watch/phone/cycling computer can all listen to one HRM at same time. BTW, which Polar BT HRMs work? Wearlink+ BT and H6 don't talk to any Polar watches, but H7 does. Wearlink+ is BT2.0 so batt dies really fast. H6/H7 are BT4.0 so batt lasts forever. However, only phones w/new BT/ANT chip and Android 4.3+ (like Samsung Galaxy 5 and Note3) work w/o a dongle.
Heart Rate Variation (HRV) Heart Rate Variation (HRV) is a measure of heart health. The analysis is done using Poincaré plot. The Heart rate of one cycle is plotted on one axes and the next one on the other axis. If heart rate was uniform and vary gradually, it would result in a straight line, but heart rate varies quite erratically and it result in quite bulging line. Contrary to common sense, irregular heartbeat which are characterised by points scattered all over and around the location of the straight line are actual indication of an healthy heart. Wish the maker of this software had some references for interpretation of the curves.
Interesting App but lack documentation Looks like a good app for measuring heart rate information. Much lacking in documentation. Works on Galaxy Note 2.
Works. Easy to set up Heart rate display clear. Does analysis (RRI) with no explanation of what it means. Ability to store and retrieve log files not clear.
Almost good Don't get the RRI readout on my phone for some reason. Other than that it seems to work ok with my polar bluetooth monitor. Wish I knew what the different graphs were showing! Just a small amount of info would be great.
It works but there is no help. Could someone explain what does the Δ+- and Δσ values mean?
