# Is PinFlag accurate and legitimate? > Canonical: https://pinflag.io/answers/about-pinflag/is-pinflag-accurate-and-legitimate Yes. PinFlag Analytics LLC is an independent company in Houston, Texas, and every number in the app is strokes gained on Mark Broadie’s published PGA TOUR baselines, the framework professional golf uses. The methodology page on pinflag.io prints the baselines, the categories and a worked hole, and the free calculators price any shot to the same figure the app shows, so anyone can check the numbers before trusting them. Topic: About PinFlag, https://pinflag.io/answers/about-pinflag ## 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.
