Ratings and Reviews

Really really BAD.


Range disappointing

Surprised that there are so view reviews even though the app is around for a while now. The HRM app is better than most I have looked at, yet still falls short of being useful for me. Would like to overlap selected graphs for comparison and annotate laps and associate notes etc. The main problem for me is the short range of the dongle. In my case it's only about 40cm. I have a polar T31 (which they recommend) and also a T61 as well as a wearlink (with new batteries). The range is never longer, yet my Polar receiver and my treadmill have a range exceeding 1m with the same belts.
In summary. It doesn't work for what I bought it for. Incidentally their other app ( ithlete HRV) has recently been improved. I would like to see a similar update for HRM. Evan though the range of the HRV app is shorter still, it does not matter for that app. For the HRM app it's a deal breaker though.



Very dated UI. Unconventional TRIMP measurement. Heart rate limit sounds stop music playing and must be manually restarted. Over priced
