# What is live or predictive strokes gained? > Canonical: https://pinflag.io/answers/strokes-gained/what-is-live-or-predictive-strokes-gained Strokes gained computed for a shot you have not hit yet. Instead of grading the shot afterward, PinFlag prices a target before you swing: it takes the expected strokes from your current lie and distance, the expected strokes from where the ball would finish at that target, and your own dispersion around the aim, and shows the strokes gained of choosing that spot. Move the aim and the number moves. It turns strokes gained from a report card into a decision aid you use while the decision is still open. 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.
