# What are benchmark lenses in PinFlag? > Canonical: https://pinflag.io/answers/about-pinflag/what-are-benchmark-lenses-in-pinflag Alternative expected strokes tables for a chosen scoring level: Tour, Scratch or a handicap level, labeled Modeled in the app. Switch the lens and every logged shot is repriced against that table, so gains and losses read on your own scale while the shots themselves stay exactly as recorded. Topic: About PinFlag, https://pinflag.io/answers/about-pinflag ## 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.
