Samsung Gear S2 or Gear Fit 2 for workout

[elron24]

I know that the newly released GF2 is more of a fitness tracker than a smart watch, but, there are very limited apps and users will solely rely on the pre-installed software. But remembering this is a new gadget, there will probably updates in its software as well as its apps. But will they make more apps for GF2? I'm afraid of what had happened with the original Gear Fit.

However, the S2 is a smart watch that has apps for fitness (e.g. Nike+, Skimble, Pear, etc.). I do interval running but I doubt both have interval running timer. Also, I workout in the gym, and would prefer to have a step by step guide or virtual coach to have on my wrist (if the mentioned apps in S2 do this). But the pedometer issues halt me to get this.

Any suggestions? Thanks!
