What's New in 4sum

1.5.0

October 28, 2026

A NEW LOOK 4sum is redesigned from top to bottom for iPhone: cleaner cards, bigger numbers you can read in the sun, a floating tab bar, and a new ? button that walks you through starting, scoring and settling a round. APPLE WATCH, REDESIGNED The Watch app has the new look and opens on the rangefinder, then Score and Games, with hole arrows on every page. The live score on your lock screen has the new look too. BUILD YOUR OWN GAME Mix parts of the 21 games into your group's own game: search for a rule, add it, and 4sum does the money. Saving a game is Pro. MESSAGES, LIVE A Messages tab with typing dots, read receipts and reactions. Hold a message to react, copy or report it. FINISH FROM ANY HOLE A blank hole gets a dot and a reminder before you move on, games skip it instead of stopping there, and the Finish screen lists what's missing. End early and only finished bets pay, with a line that says what was voided. SETTLE UP, PROPERLY Tick off each payment as it's made and it stays ticked in History. Change a game mid-round and choose whether it applies from this hole on or to the whole round. GROUP ROUNDS THAT STAY IN SYNC The host's Finish closes the card for everyone. Tees, strokes, presses and Longest Drive sync across phones, and a late joiner is offered into the games from the hole they joined. COURSES A round keeps the tee it was played on, so a corrected scorecard never changes an old round. Course search forgives spelling and sorts by nearest. Can't find a course? Request it and we'll add it to the directory. BUG FIXES - Scores entered before you share a round now reach everyone who joins. - Friendly rounds count points, not dollars, in History, totals and the share card. - A round on the back nine shows holes 10-18 and the right Out and In. - Handicaps on 9-hole courses are worked out correctly. - Scramble no longer mixes tees, and a leftover cent is split the same way in every game. - Clearing a hole in an event clears it on every phone. - The unread badge and Messages agree. - With location off, the rangefinder says so instead of loading forever. - Deleting a round also deletes its clips. - Pro now belongs to your free account, so it follows you to every phone you sign in to. - Blocking covers search, maps and round chats, and handles and names are checked for offensive words. - And lots of smaller fixes.

Great app

Great app, great using on the golf course!

Amazing App

I’ve been looking for an app to help track side games while playing a round. This app is the answer. You are easily app to settle up while not having to keep track of the score. It allows you to focus on not shanking your next shot.

Ideal for a good time

My buddies always set off to play a game and by home 12 or 13 everyone tends to lose track. This app does a great job of handling that

Superb Game Tracking

I’ve waited a long time for a quality, free/cheap golf side game tracker. Normally I spend 20% of the time on the course acting as book keeper rather than watching shots and participating in the games. That problem is solved with 4sum! Looking forward to future updates!
