Finding one app that handles scoring, side bets, and group logistics without making everyone download something first is harder than it should be. Most apps do one thing well and leave you sorting out Venmo requests on the walk back to the car.
Here is what five of them actually do, where each one stops, and which type of golfer it suits.
1. caddie.fun: best for crews that bet
Best for: groups that want format math and settlement running inside the live round
caddie.fun covers more of the round than the others here. Set up a round, invite your crew, and everyone scores in real time from any device. No download required, which matters more than it sounds when you are on the first tee trying to get four people into the same app.
The betting side is the real separation. Wagers run as live state on the card across 22 game formats: Nassau, skins, match play, Wolf, best ball, with presses. Pick the format before the round and the standings update hole by hole instead of getting reconstructed from memory in the parking lot.
Money runs on two rails, and the difference matters. In-app pots are cfUSD play money (no cash value today). Real cash between friends settles through Venmo, confirmed against the round ledger, so the app does the format math and the humans move the dollars. Mainnet stake rails stay gated until the contracts are deployed and audited.
It also includes a GPS rangefinder and an AI caddie that builds on your history for club picks and strategy, plus trip tools for expense splitting and rotating foursomes.
Where it falls short: the course database is roughly 200+ courses against 40k+ for the GPS giants. There is no official GHIN posting; the index is WHS-style and computed in-app. If your primary job is course coverage or an official handicap, lead with a different app.
2. 18Birdies: best for swing coaching and casual scoring
Best for: golfers who want GPS, swing analysis, and light game tracking
The free tier covers GPS yardages, basic scoring, and 50,000+ courses. Paid tiers add an AI swing analyzer, video coaching, and game-result tracking across a handful of formats. The GPS is reliable and the swing tools are genuinely useful between lessons.
Where it falls short: no automated wager settlement. Its Payout feature answers "who owes whom" after the fact, which is a calculator sitting beside the round rather than a format engine inside it. If your group plays Nassau with a press, you are still doing that math yourself. Requires a download, and the best features sit behind the paywall.
3. TheGrint: best for handicap tracking
Best for: golfers who want a USGA-linked index and verified round history
TheGrint posts to your official USGA handicap, which makes it the right call for club events or any time you need a portable, verified index. GPS covers 40,000+ courses and the social side is active. For competitive club players, that official posting is genuinely hard to replace, and caddie.fun does not try to.
Where it falls short: no betting features. If your group plays for money, this is not that tool.
4. Settle Up Golf: best for side-bet tracking
Best for: golfers who already have a scoring app and just want side-bet tracking
A focused tool. It tracks side bets during a round, connects to Venmo for settlement, and supports GHIN posting. If your only friction is settling up at the end, it solves that cleanly.
Where it falls short: no GPS and no trip logistics; scoring is side-bet-centric, not a full round-tracking experience. If your group needs a real scorecard or course data, keep your main app.
5. Skins App: best for groups that only play skins
Best for: a fixed weekly skins or Nassau game
Built around a library of 25+ formats — skins, Nassau, Banker, Vegas, Wolf, Hammer and more. Settlements run on your own P2P rails (Venmo, PayPal, Zelle, Cash App); a $40/yr subscription unlocks the full game library.
Where it falls short: no GPS, no trip tools, and the settlement math is on the group — Skins tracks the game, you still move the money. The subscription adds up over a season.
How they compare
| App | No download | Formats | Settlement | GPS courses | AI caddie | Trip tools |
|---|
| caddie.fun | Yes | 22 | cfUSD pots, Venmo for cash | ~200+ | Yes | Yes |
| 18Birdies | No | Several | Manual (Payout calculator) | 50,000+ | Swing only | No |
| TheGrint | No | None | None | 40,000+ | No | No |
| Settle Up Golf | No | Side bets | Venmo link | None | No | No |
| Skins App | No | 25+ | P2P (your rails) | None | No | No |
Note the columns caddie.fun loses. Course coverage is not close, and official GHIN posting is a real gap.
One app is a marketing fantasy. A deliberate stack is an operating system.
Run a 20-minute bake-off
Do not trust anyone's feature grid, including the one above. On your next casual nine:
- Create a four-player round with a Nassau and one press.
- Enter messy scores: pickups, edits, a wrong hole fixed two holes later.
- Share a spectator link with someone who has not installed anything.
- Ask your most skeptical friend whether the end screen is auditable.
Feature grids lie. Friction does not.
The Cut
If your group plays for money in anything beyond basic skins, caddie.fun runs the formats and the ledger in one place, and the no-download spectator link removes the biggest barrier to getting everyone on the same system. If swing improvement is the priority, 18Birdies. If your index matters most, TheGrint.
Two-app stacks are rational: TheGrint for the official handicap career, caddie.fun for the Saturday game. Pick for the job you actually run every weekend, and start at why caddie.
