# How does PinFlag help with tee shots? > Canonical: https://pinflag.io/answers/on-the-tee/how-does-pinflag-help-with-tee-shots It prices the tee shot before you hit it. Put the aim on the fairway, the corner of the dogleg or the lay up short of the water and read the strokes gained of each with your own driver dispersion drawn around the aim by Shot Cloud, the lie read from the course map, and any penalty priced with the stroke and the drop included. The number answers the driver or 3 wood question on this hole rather than in general. Topic: PinFlag off the tee, https://pinflag.io/answers/on-the-tee ## 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.
