Keep the round. Share the story. Karta is your personal golf book for iPhone. Record a round, look back at your results and turn the moments worth keeping into a shareable card. No account required, and scoring works offline. SCORE SOLO OR WITH YOUR GROUP Play 9 or 18 holes and record each score with clear, simple controls. Add putts and fairway direction when you want more detail. Playing together? Keep scores for 2–4 golfers on one phone, with stroke play, match play, gross or handicap Stableford, Skins or custom points. Handicap Stableford requires complete course data and each golfer's handicap, with everyone playing the same tees. KEEP THE WHOLE ROUND Return to a completed round for the same full recap: score to par, front and back nine, standout holes and earned titles. Reopen every hole, correct a score or pick up an unfinished round. When plans change, end the current round and start another from Home without losing the scores already recorded. UNDERSTAND YOUR GOLF See recent form and average strokes on par 3, 4 and 5 holes, with separate views for 9- and 18-hole rounds.

Choose Story, Square or Portrait, then a graphic, photo or transparent background. Eight graphic styles include Heritage, Royal blue and Pencil. Solo and group cards can show the full scorecard or emphasize the result with the Number layout, independently of the background. Save to Photos or use the iPhone share sheet. You choose whether to include group names and other details. Transparent PNGs can be manually placed over a Story or photo in another app. FIND YOUR COURSE, OR ADD IT Search the bundled offline catalogue for the United States, Spain, Germany, Austria, Slovakia, Czechia, the United Kingdom, Ireland, Canada, Japan, Australia and New Zealand. Choose the course, layout and tees separately. Use available scorecards or enter a course manually. Location is optional. English and Czech. Your rounds, practice, profile and titles stay on your iPhone unless you choose to export or share them. The Czech feature name remains Úspěchy. Course coverage and available details vary. Course-aware net and Stableford results require a saved handicap and complete rating, slope, par and stroke-index data. Karta does not issue or update an official handicap. Group results are separate from solo statistics and titles.
