The Alarm Clock on the Gear Fit 2 is one of my favorite features. The difference between waking up to a blaring, loud, and jarring sound alarm vs a soft wrist vibration is astronomical!
It helps not wake up the wife when I get up earlier. Great stuff. I do know that this feature is on a lot of other wrist smart devices, so its not entirely unique with the Fit 2. However, I can say that it works flawlessly the first and 100th time with the Gear Fit2.
