4sum
Golf side games, settled up
Free · Designed for iPhone. Not verified for macOS.
Twenty golf side games, scored as you play and settled to the fewest payments at the end. Free, no account, works with no signal.
4sum runs your group's golf bets. Twenty side games, scored as you play, and at the end it tells you exactly who pays who.
No more napkin maths on the tailgate.
TWENTY GAMES, NOT FIVE
Wolf, Nassau with presses, Skins with carryovers, Vegas, Banker, Bingo Bango Bongo, Snake, Sixes, Rabbit, Dots and junk, Left-Right, Scotch, High-Low, Niner, Match Play, Best Ball, Stableford, Stroke, Scramble and Longest Drive. Run as many at once as you like on the same card.
IT TEACHES THEM TOO
Every game has a how-to and a worked example, because the hardest moment in a side game is the tee box where somebody says "wait, how does this one work?" Nobody else explains them. We do.
IT SETTLES UP
At the end, every game is netted across every player and reduced to the fewest possible payments. Not a table of who owes what to whom eleven times over, just "Mike pays Pat $45." Tap a player's Venmo handle to open their profile. 4sum never touches money itself.
IT TELLS YOU WHAT THE HOLE IS WORTH
A strategy helper works out what is actually on the line before you hit, from the real state of every game you have running. It cannot disagree with the money, because it reads the same numbers.
EVERY COURSE IN THE US
Search by name or town and add any of 30,000+ US courses with one tap, scorecard, tees, ratings and slope included. Add your own if it is not there.
GPS DISTANCES
Front, middle and back of the green, live as you walk. Tap Find on map and 4sum pulls the greens from OpenStreetMap where they have been mapped, or stand on a green once and mark it yourself. Tap anywhere on the hole for the carry and what is left from there. Mark your own bunkers and layup targets once and they read out on every round after.
LONGEST DRIVE, MEASURED
Mark the tee, hit, mark the ball. Add the game whenever you feel like it and use it on whichever holes you want.
LIFETIME RECORDS
Every finished round adds up: lifetime money, rounds won, and a head-to-head record against everyone you play with.
FREE, AND IT STAYS THAT WAY
No account. No ads. No subscription. Nothing to sign up for. Your rounds live on your phone and work with no signal, which is what you want on the back nine anyway.
4sum is a scorekeeper for friendly wagers between people who already play together. It does not process payments, take a cut, or hold anybody's money.
Search by town. Type a city and 4sum lists every course around it, nearest first, not just the ones with the town in their name.
Near me finds the course you are actually standing next to. It used to miss the closest ones in busy areas.
The Apple Watch now shows your round: the hole, the yardages and the scores.
A round timer shows how long the group has been out, on every hole.
Courses that are on the map but have never been named can be set up in a tap.
Smaller fixes throughout.
