Samsung better add a SWIMMING option in the menu (as well as their S Health app) this time around. The current Gear has an option of adding it as one of a bunch of hidden activities but it's not created equal with running or cycling, for instance. It's a real shame, Samsung. Fix this. People do swim! Ask Garmin.
I seriously can't believe how much the UI has changed from the 1st-gen Gear Fit. The UI is simply beautiful and clean--no doubt. Kudos to Sammy.
