# Can a beginner use the PinFlag calculators for free? > Canonical: https://pinflag.io/answers/beginners/can-a-beginner-use-the-pinflag-calculators-for-free Yes. The strokes gained, expected strokes, club distance, course handicap and golf handicap calculators on pinflag.io are free, need no account and run on the same baselines as the app, so a beginner can price a shot in the browser before the app is on their phone. Topic: PinFlag for beginners and high handicappers, https://pinflag.io/answers/beginners ## 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.
