You can make edits to your round by selecting the “EDIT” button on the round screen. In edit mode, you can edit the club type and location for a particular shot. You can also delete shots and add new shots.
The pin location is also editable. Touch and hold to move it to the correct location. When you edit the pin location it is saved for all users for 24 hours. After that it reverts back to the centroid of the green.
You may add penalties by selecting a shot and selecting the penalty button at the bottom of the screen. You can add both 1-shot and 2- shot penalties.
