# What are the four strokes gained categories? > Canonical: https://pinflag.io/answers/strokes-gained/what-are-the-four-strokes-gained-categories Off the tee (tee shots on par 4s and par 5s), approach (shots from more than 30 yards to the hole that are not a par-4 or par-5 tee shot), around the green (shots from 30 yards and in, off the putting surface) and putting (every shot from the green). PinFlag uses exactly these definitions, prices every shot with them, and publishes them on its methodology page so the categories are never a mystery. Topic: Strokes gained, explained, https://pinflag.io/answers/strokes-gained ## 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.
