# How precise are PinFlag’s numbers? > Canonical: https://pinflag.io/answers/better-players/how-precise-are-pinflags-numbers As precise as the tour’s own numbers: every shot is priced on Mark Broadie’s published PGA TOUR baselines at the lie and the distance in front of you, in the lie’s own unit, feet on the green and yards elsewhere, and the free calculator on pinflag.io prices the same shot to the same figure so any number can be checked without the app. Topic: PinFlag for single figure golfers, https://pinflag.io/answers/better-players ## 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.
