# Do I need a launch monitor to start with PinFlag? > Canonical: https://pinflag.io/answers/getting-started/do-i-need-a-launch-monitor-to-start-with-pinflag No launch monitor is needed to start. Logged rounds produce full strokes gained on their own, and the number before the swing runs on a benchmark dispersion pattern labeled Estimated until your own data exists. A launch monitor session makes the pattern yours and moves the label to Measured; so do the shots you log on the course, because each one records the target and the result. Topic: Getting started with PinFlag, https://pinflag.io/answers/getting-started ## 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.
