Golf, hole by hole.
TeeUp is a golf companion for players in Portugal: scorecards, the official handicap, nearby courses and rounds with friends.
A round is four hours. The app should need seconds.
On the course nobody wants to type. TeeUp records a hole with a few taps: strokes, putts, fairway and penalties, and keeps the total against par in view.
It is offline first: everything is saved on the phone and synced when the signal comes back, which on most Portuguese courses is a real concern.
Nine holes, as you scroll.

Decisions
The official handicap
The handicap index follows the World Handicap System: the best 8 of the last 20 differentials, adjusted for each course’s rating.
Courses nearby
Google Places and MapKit find courses around you; WeatherKit adds the wind at the tee.
Undo on every hole
A wrong tap is fixed with undo, and scores can be exported as CSV or JSON.
Rounds with friends
Play the same round on several phones and see everyone’s card fill in.
