Golf apps track your score.
We track your game.

Most golf apps are glorified scorecards. You enter a number, it shows a graph, and you move on. Nothing about why you shot that number. Nothing about the mental side. Nothing about whether you're actually getting better at the things that matter.

GolfStack is different. When you log a round, you log how you played — fairways, putts, greens in regulation. You answer one mental game question per hole. And after the round, AI reads the patterns and tells you what it sees — in the warm, grandfatherly voice of Harvey Penick, not a stat dump.

The consistency score — 0 to 100, combining driving, putting, and scoring — exists because handicap doesn't tell you enough. Two rounds can post the same number and feel completely different. Consistency captures that.

The mental game profile — five constructs tracked across holes over time — exists because golf is played between the ears. Commitment, routine, reset, aim, steadiness. These matter more than swing mechanics for most amateur golfers.

GolfStack is built for the golfer who wants to understand their game — not just report their score.
