THIS IS ONLY FOR Samsung Gear Fit 2 App to iPhone
I Also know how to do it on Gear S 3 ;-) (Just ask me lol).
OK like I always say ... here is the deal ... I was not member of this website but I registered only for one reason to answer you question lol :-).
You will need to download and install MEGA App on your iPhone. than you will download the Samsung Gear Fit 2 App from here:

Your next step is to connect your iPhone to the computer and then you will open the file within itunes. and you will install it. you will do all of that in itunes under apps. Cool?
You will need to visit this website if you need step by step help:
