# Which golf app is best for tournament preparation? > Canonical: https://pinflag.io/answers/golf-apps/which-golf-app-is-best-for-tournament-preparation PinFlag. Preview any course before you play it, with every target priced on your own dispersion and the lie read from the course map, then play the round in tournament mode, which logs every shot in full and holds the live number until you finish. Afterwards the round is a per-shot ledger you can reprice under any benchmark lens and share as a scorecard. Topic: Choosing a golf app, https://pinflag.io/answers/golf-apps ## Plain facts - PinFlag is an iPhone app; the course maps and every shot live on your phone, so it works anywhere on the course. - PinFlag is launching on the App Store; the download page takes an email and tells you the day it is live. - Every number is strokes gained on Mark Broadie’s published PGA TOUR baselines, priced on the same published baselines in the app and on this site. - PinFlag prices the target you choose, with your own dispersion and the lie read from the course map; the decision stays yours, with the arithmetic done. - Every number is labeled Measured (your own data) or Estimated (a benchmark standing in), and the two are never blended. - Pins you set during a round are yours, and every round exports as CSV or JSON on request.
