Wanted to start a new thread, but hopefully I'll get answers right here. TL;DR in last paragraph below.
I'm training for long distance running events. Thank goodness I've discovered so early on that my smartphone places a burden on me after a certain mileage. I've tried armbands and other ways of carrying it, but it's uncomfortable. I went into a Samsung store and saw the different Gear S models (S2 and S3).
From these comments...I had no idea about the Gear Fit. Seems that the Fit2 will suit my needs adequately...except that I also want a smartwatch (played with the Gear S3 for a few minutes). My chosen app is Nike Running, but since their partnership with Apple (exclusive Apple Watch deal), I'm willing to export my data (or lose it all forever) and change apps if I must.
TL;DR I need a watch that I can take on long runs without a phone, and later on upload my results to an app for runners.
