Four steps. Then you go and play golf.
The whole point of the app is that it gets out of the way. Setup takes under a minute, and each hole takes a few seconds between two shots.
1
Pick a game
Wolf, Skins, Nassau, Vegas, Dots or Team Match. Tap the one your group wants — and if somebody does not know it, the rules screen explains it in two minutes.
- Wolf
- Skins
- Nassau
- Vegas
- Dots
- Team Match

Add your group
Three or four players, picked from your saved list. Set the course, and even it up with handicaps if you want to — the app shows what everyone plays off before anyone tees off.
- Saved players make it a few taps, not a form.
- One switch evens it up with handicaps — and shows what everyone plays off before anyone tees off.
- Save the whole setup as a preset for next Saturday.

Play golf
Enter scores as you go. One decision on screen at a time, buttons big enough for a gloved thumb, and the whole thing takes a few seconds between two shots.
- Score entry defaults to par, so a par is one tap and a birdie is two.
- The steppers are 56px squares, sized for a gloved thumb rather than a mouse.
- Nothing advances underneath you — the result stays on screen until you leave it.
- Undo is always one tap away and says what it will undo.

Let the app do the maths
Points, teams, carries, presses and standings update themselves. You put the phone away and go and hit your next shot.
- Points, teams, carries, presses and match status all update themselves.
- The leaderboard shows movement as well as position.
- Any earlier hole can be corrected and everything recalculates instantly.
- The final result is on screen the moment the 18th is in.
Underneath
One idea makes all of it work.
A round is stored as the setup plus a list of holes. Everything else — standings, match status, presses, carries, the final result — is worked out from those holes every time they change.
Undo works
Because nothing is stored as a running total, undoing a hole is just removing it.
Editing works
Fix the 4th on the 12th tee and the whole round recalculates in front of you.
Resuming works
Close the app mid-round and reopen it: there is no hidden state to lose.
