# What is the difference between a golf GPS app and a strokes gained app? > Canonical: https://pinflag.io/answers/golf-apps/what-is-the-difference-between-a-golf-gps-app-and-a-strokes-gained-app A GPS app answers how far it is. A strokes gained app answers what the shot is worth. PinFlag does the second with the first built in: the distance to the pin you placed and to any target, plus the strokes gained of that target with your own dispersion and the lie read from the course, so the yardage becomes a priced decision. 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.
