This. I discussed this with my cardiologist last year and he said the only device they recommended was an Apple watch. They have now expanded the recommendation to include some of the Samsung watches as well. Standard HRM systems like a chest strap record heart rate very accurately but lack the analysis software that can detect abnormal conditions. He also liked that I could show him my cycling and skiing workouts on my phone. Said it provided more than enough evidence that a stress test wasn't warranted.


I used a RFLKT+ for years, never really saw any reason to get a GPS bike computer because it worked so well. That was until last year when Wahoo pushed an updated phone app. Then the RFLKT+ became very unstable, often locking up or shutting off mid ride. In the past when I had those issues the phone app continued to work, but in this case the phone app WAS the problem. After a few of weeks of dropped rides, lost data, corrupted data, and no updates from Wahoo Fitness I finally had enough and bought a Garmin 130. I really wish I had done is sooner. It's about the same size as the RFLKT+ but does SO MUCH more, and has yet to drop a ride on me (at least it hasn't. I've managed to cause it to drop a couple of rides doing things I probably shouldn't be doing while recording a ride. And now that I have a Varia taillight it is even more useful.) I can honestly say the Garmin 130 was money well spent.
