Your insights live here. HOW IT WORKS 1. Snap a photo of your performance log, drives, and approaches pages after your round. 2. Journal18 reads the scores and stats with AI, then shows you everything it found. You review and confirm anything uncertain before it counts. 3. Every confirmed round builds your history, your trends, and your benchmarks. Prefer to type it in? Manual entry works too, hole by hole or as a quick summary. No photo required. WHAT YOU WILL SEE Round history. Every round saved with scores, stats, and notes, ready to revisit. Scoring trends. Watch your scoring move across rounds instead of guessing from memory. Drive patterns. Fairways hit, miss directions, and a landing board that shows where your tee shots actually finish. Approach proximity.
