Interstate Tracker

Interstate Tracker records which parts of the U.S. Interstate Highway System you have driven, and maps what is left. An Android app records the drive — or imports a GPX file — and matches the trace against real interstate geometry; the web app renders your coverage back per route and per state.

The web app and the sync API are live. The Android app is not publicly released.

Interstate Tracker Privacy Policy

This policy is superseded and is kept only so its original URL keeps working. It describes the earlier device-only version of the app, which had no internet permission. That is no longer how Interstate Tracker works: the current app syncs to a server.
