Scoring and betting feel secondary to the handicap-tracking core. The scorecard entry flow exists mainly to feed the handicap calculation, not to run a live multi-game betting session — there's no equivalent of voice entry, no real-time hole-by-hole betting engine running several simultaneous games (skins, a nassau, a side press) off the same scores.
No real per-hole stroke allocation across simultaneous games. A handicap-tracking tool needs a rolling index at the end of a round; it doesn't need to know which specific stroke-index holes each player gets a shot on for three different bet formats running at once. That's a different, more demanding job than what the product is built around.
The interface shows its age. TheGrint has been around a long time and it shows — a dated, form-heavy UI that a lot of users tolerate because they're already invested in their handicap history there, not one built for a first-time player to pick up in a minute mid-round.
No live spectator experience. There's no share-link concept for a friend or family member to watch a round update live from their phone — following along means waiting for someone to report back after the round, same as it would with a paper scorecard.
Money settlement isn't really part of the product. Any actual wager still gets settled the old way — mental math or a separate app — because TheGrint's own flow ends at a posted score and an updated index, not a "here's who owes who" screen.
