What separates a golfer stuck in the 90s from one who breaks 90?
Before the swing, it's the scorecard. Write down only your total and you'll never know which holes cost you strokes, or why. Start tracking greens in regulation, fairways and putts, and what to fix shows up in numbers.

PARON is a personal scorecard for golfers who take their game seriously.

■ Know your game
Two or three taps after you hole out, and that hole is done. When the round ends, PARON works out GIR, fairways hit, average putts, 3-putts and your score distribution. The Stats tab shows your average score, putts, GIR, FW and score distribution for your last 3, 5 or 10 rounds or all of them, with 9-hole and 18-hole rounds tracked separately, and trend charts once you have 5 rounds. You can only fix the weaknesses you can see.

■ Ready on the first tee in seconds
No login, no sign-up. Recording, saving and stats all work offline (no bars on a mountain course, no problem), and a round uses no mobile data. Hole-by-hole pars for 473 golf courses across South Korea are built in (1,137 courses and nines, listed by their Korean names): pick the course, tap its OUT and IN nines, and every hole's par fills in. Anywhere else, type the course name and set each hole's par as you go.

■ The look of a paper scorecard, records that stay on your phone
A circle for a birdie, a double circle for an eagle, a square for a bogey: the notation of a paper scorecard, set exactly the way you'd write it. Round records are never sent to a server, so your scores stay on your phone. And there are no ads on the screens you use during a round. Not getting in your way while you keep score is the rule.

Notes
• Course par data: the Korean Ministry of Culture, Sports and Tourism's national golf course survey (2024-12-31) and each club's official website. Courses not on the list (outside Korea, golf simulators and so on) can be entered by hand.
• Course not on the list? Send us its website address from the Round setup screen in the app. We'll check it and add it as soon as we can.

Round records are kept in the app's local storage and can be lost if you delete the app or reset your device, so keep a copy with "Export records (Excel file)" in the Records tab. Android's system backup covers only the app's database and preferences; on Android 12 or later, cloud backup runs only if the device can encrypt it. Depending on your system settings, this data may be restored from the backup stored in your Google account or transferred to a new phone; the developer does not collect or view these backups.
