RuleCaddie

Ball in the water? Plugged in the fairway? Ask out loud and get the ruling with the exact rule number — before your playing partners finish arguing.

Your pocket rules official.

Describe any situation on the course — out loud or typed — and RuleCaddie answers in seconds with the ruling, your options, and the exact USGA/R&A rule number. No more scorecard arguments, no more guessing on the drop.

ASK ANYTHING, HANDS-FREE Tap the mic and talk: "my ball's against a tree root, can I take relief?" Answers stream in instantly and can be read aloud while you walk to your ball. Smart follow-up buttons handle the "red stakes or yellow?" details with one tap.

YOUR CADDIE KNOWS YOUR COURSE Photograph the local rules board and scorecard once — RuleCaddie remembers them forever. Every answer accounts for your club's local rules, and your handicap marks exactly which holes give you strokes.

SEE YOUR DROP The Drop Helper draws your actual relief area on a satellite map — two club-lengths from where you crossed the line, or the back-on-the-line corridor.

ROUND MODE Start a round (it can detect the course automatically), tag rulings by hole, log penalties, and get a recap when you're done. Your round follows you on the lock screen, in the Dynamic Island, and on Apple Watch.

LEARN THE RULES FOR GOOD A daily 3-question quiz with streaks and badges, format explainers (match play, Stableford, foursomes, handicap allowances), and study tracks for aspiring rules officials. The complete rule book summary works offline.
