# Does PinFlag show club gapping? > Canonical: https://pinflag.io/answers/launch-monitors/does-pinflag-show-club-gapping Yes. Per-club carries from your imported sessions make a twenty-yard hole between two clubs visible at once, which is invisible on a range where every ball is a fresh attempt at the same target. The free launch monitor analyzer on pinflag.io reads a session export in the browser and flags gaps with what each pattern costs in strokes. 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.
