Flash Caddie: Golf Scorecard

Flash Caddie is the cleanest way to keep score on the course.

Built for golfers who want a digital scorecard — not a second job. Record your round hole-by-hole, watch your USGA handicap index update automatically, and see your game trend over time. No shot tracking. No leaderboards. No noise.

WHY FLASH CADDIE

Most golf apps want to be everything: GPS, social feed, shot-by-shot analytics, video lessons, virtual pro shop. Flash Caddie does one thing and does it beautifully — it keeps your scorecard.

If you've ever pulled your phone out on the 7th tee and spent two minutes hunting for the "+1" button, Flash Caddie is for you.

ABOUT THE HANDICAP INDEX

Flash Caddie calculates your index using the USGA World Handicap System formula:

differential = (113 / slope) × (adjusted_score − course_rating)

Your index is the average of your best 8 differentials from your last 20 rounds. Fewer than 20 rounds? Flash Caddie uses the reduced-count table so you get a meaningful number from round one. Rounds played on courses without a rating and slope are excluded automatically.

Prefer to use your official club handicap? Toggle the manual override in Settings.
