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.

Verdict
The clearest difference is update cadence: TheoryGolf at weekly against DECADE's every 2 months. DECADE's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 17.2). On price, ads and in-app purchases there is nothing between them.
