# What does PinFlag do with a launch monitor session? > Canonical: https://pinflag.io/answers/launch-monitors/what-does-pinflag-do-with-a-launch-monitor-session It turns the session into a per-club pattern: carries, spread and gapping, labeled Measured. Those patterns then stand behind every predictive strokes gained number on the course and every dot in Shot Cloud. Outliers are flagged for you to judge rather than silently deleted, so the pattern is yours in every sense. Topic: Launch monitors, https://pinflag.io/answers/launch-monitors ## 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.
