The betting features are simplified, not comprehensive. 18Birdies covers a handful of the most common bet types reasonably well, but it isn't trying to be a full betting engine — no wolf, no banker, no snake, no dots, no the dozens of side-game formats real groups actually run across a season. The moment your group's "the usual games" list is longer than nassau and skins, there's nowhere to go.
Handicap-aware stroke allocation isn't the product's focus. A GPS/stats app's handicap number exists mostly to contextualize a round, not to drive hole-by-hole stroke allocation across several simultaneous betting games with different rules for who gets a stroke where. It's a different level of precision than a product built around settling real money needs.
No real spectator experience. There's no live-watch link for a friend, spouse, or the guy who couldn't make the round to follow along in real time — the app is built for the person playing, not for the people around them who want to check in from the clubhouse or from home.
No season-long structure. A recurring group — a weekly game, a league, a multi-week club series — has nothing here to tie rounds together: no standings, no recurring roster, no running ledger of who's up for the year. Every round is its own island.
Ads and a subscription paywall sit between you and the features you actually want. As a free GPS app supported by ads and a premium tier, the core betting/scoring flow can feel like it's competing for space with the app's actual business model, rather than being the whole point of opening it.
