My opinion is that GolfPad is superb when linked between your (In my case, Samsung) phone and Gear fit2 pro smartwatch. I paid the $20 = it is easily worth it.
On your watch during play, you have distance to the green and ability to keep score directly from the watch. Shot tracking (look it up) is also available. There's more. Flawless so far for me. If you need more detail, like accurate overhead view of the hole or distance to hazards, just pull out the phone. Otherwise, leave the phone in your pocket or on the cart.
