Never argue about a ruling again. GolfRef is the essential reference app for American golfers — whether you're a weekend warrior, a new player trying to learn the game, or a seasoned player who just blanked on the drop procedure. [RULES] 10 of the most common on-course situations explained in plain English — not the stuffy R&A rulebook language. OB, lost balls, penalty areas, bunkers, embedded balls, flagstick rules, and more. Every rule includes a Pro Tip so you actually remember it next time. [SLANG DICTIONARY] 28 golf terms from Ace to Yips. Know what a Snowman is. Understand why nobody says "shank" out loud. Learn the difference between a draw and a hook, a chunk and a skull. Each term comes with a real-world example so it sticks. [PENALTY CALCULATOR] The fastest way to know your ruling. Pick your situation — OB, lost ball, water hazard, unplayable lie, wrong ball, bunker violation, flagstick — answer one question, and get a clear verdict: how many strokes, what to do next, and whether there's actually no penalty at all (it happens more than you think). [WHY GOLFERS LOVE IT] - Clean dark interface — easy to read in bright sunlight - Works 100% offline — no signal needed on the course - Covers the 2019 rules updates (flagstick, bunker loose impediments) - Fast enough to use between shots without slowing down your group Stop guessing. Stop arguing. Just open GolfRef.

The clearest difference is in-app purchases: Golfbook at none against Rules Now's 1. On price, ads, device support and iOS requirement there is nothing between them.
