TheoryGolf — AI Caddie & Strokes Gained TheoryGolf makes you smarter on the course and untangles the complex patterns in your game — all without changing your swing. Meet Theory: your AI caddie, analyst, and coach. Theory studies every round, finds where your strokes actually go, and tells you what to do about it in plain English. Play smarter on every hole with GPS distances, elevation, wind, and green contours. Then see exactly where you're losing strokes with the same strokes-gained analytics the pros use — off the tee, approach, short game, and putting. Strokes gained doesn't tell the whole story, so Theory pieces it all together, chains the why behind your scores, and hands it to you in a format that actually makes sense. ON THE COURSE • GPS rangefinder with distances to front, center, and back • Elevation-adjusted "plays-like" yardages • Wind, hazard, and green-contour overlays • Smart shot and club recommendations from Theory • Easy shot-by-shot or one-tap scoring • 3D contour maps — green contours on every hole, full-hole maps where we have coverage STATS YOU WON'T FIND ANYWHERE ELSE • Reads deep patterns — how you score by pin position, how wind really affects you, and where your bogeys actually come from • Tracks how often you short-side yourself • Measures how often you actually pull off the shot you intended • Auto-reads your putts to find where your stroke is sharp or leaking KNOW YOUR GAME • Tour-style strokes gained for every part of your game • GIR, fairways, putts, scrambling, and proximity stats • Traceable bogey analysis — see the chain of shots behind every blow-up • Personal benchmarks and trends over time • Automatic WHS-style handicap tracking • Round-by-round and course-by-course breakdowns SINGLE & MULTI-ROUND ANALYSIS • Single-Round Analysis — strokes gained, GIR/putts/fairways, benchmarks, and correlations for any round • Multi-Round Analysis — wind impact, scoring patterns, club analytics, putting & short-game trends, and an AI diagnosis of your biggest leak • Both are powered by Theory, who knows exactly who you are as a player and reads your rounds to diagnose what's really going on GET BETTER, FASTER • Ask Theory anything about your round or your overall game • Personalized practice plans built from your real misses • A focused drill library for the range, short game, and green — from feel and contact to pressure and mental reps • Goals and training tools to track your progress PLAY WITH FRIENDS • Multiplayer rounds with live leaderboards • Add friends and share your results TheoryGolf is free to download.
