Contourfall

Read the land. Find a path.

Purpose-Built

A quiet route-planning puzzle built from real contour logic: read slope, saddles, ridges, drainage, exposure, and limited stamina to guide expeditions home.

Core Features

  • Tap adjacent contour cells to draft a route and see cumulative cost immediately
  • Close contour spacing raises grade, fatigue, and descent risk
  • Ridges, saddles, streams, cliffs, and weather alter legal movement
  • Optional survey marks reward accurate elevation and bearing estimates
  • One hundred authored sheets, daily expeditions, and free-map mode are included

Private by Design

No account, subscription, ads, tracking, third-party analytics, or developer-operated backend. Core features work offline, and your work stays on device unless you deliberately share or export it.
