Built for a clearer ski day
Mountainmapper is developed by Otto Zhang in France. Use the language menu for translated website pages. Check the app’s language settings for your installed version. Core maps and standard route planning work without an account.
The product focuses on choosing a destination, understanding piste and lift connections, and preparing offline data. The public route examples show the calculation inputs so readers can distinguish a software result from an on-mountain test.
How we verify a route example
We record the public endpoints, difficulty limit and map release, run the calculation, and compare the exported steps with the article and route drawing. The UCPA–Courchevel example was rechecked on 30 October 2026. Its green-only and blue-allowed outcomes are published together.
A planning aid, with clear limits
Map data can be incomplete or out of date. The app does not provide live piste closures or guarantee route safety. Always follow resort signs, closures and staff instructions. Product screenshots on this site show the app; they are not evidence that every pictured connection is currently open.
Help improve the experience
For a map issue, app problem or suggestion, contact support with a short description, your device and app version. Do not send passwords or precise location data. The privacy policy explains how personal information is handled.
Version and verification records
Screenshots are tied to the version and capture date shown in their captions. Store releases can differ by platform and region; use the official store version history for the release available to your device. These records describe what was checked, not a guarantee of current lift operations.
