With Magellan Echo and Golf Pad you can always see the distance to front, middle and back of the green on the smartwatch, change current hole, track shots and record putts and penalties. The green distances are in the middle of the watch screen. Current hole and par is on the left. Score is on the right.

Use the upper and lower right buttons to navigate between the holes. Lower left button adds a stroke. When you press it, Golf Pad shows the screen with the shot distance. If you do nothing, it will track a shot by default. You can however change it to putt or penalty using the upper and lower right buttons. 

Finally, the upper left button is Undo for the last action.
