Crosscheck

Support

Crosscheck is a study aid for checkride preparation — not flight instruction and not a source of operational flight information. Verify everything against your POH and current FAA publications.

Common questions

Where is my data? On your device. There are no accounts and no cloud sync — see the privacy policy. Deleting the app deletes your progress and logbook, so export anything you need first.

The numbers don't match my airplane. They shouldn't be trusted until you set them: V-speeds, empty weight & CG, and your aircraft details are all editable in Settings. The shipped values are examples for a typical PA-28-151.

Weather isn't loading. The live METAR comes from aviationweather.gov and needs a network connection and a home airport set in Settings. The app falls back to its practice METARs offline.
