# FAQ ### How is this different from Caltopo, Gaia, etc.? Backtrack has many of the same features as other backcountry mapping apps, along with numerous unique features to help make your next backcountry outing a success. We have many powerful layers tailored to backcountry skiing that no other app does, such as avalanche observations, Mountain View, real-time sun exposure, over 800 ski tour routes, slope angle & aspect highlighting, and more. We are focused on making the best mapping tool for backcountry planning. ### Is this app just for backcountry skiing? We started out as a backcountry skiing app, but with our recent version 2 update we have expanded into a fully-featured backcountry mapping app. ### Which areas are supported? Users anywhere in the world can use Backtrack's advanced mapping tools to plan and share their adventures. Some of our data layers are restricted to the western United States (i.e. ski routes, avalanche forecast & observations, etc.). ### What map layers are available? You can see them all [here](/backtrack-docs/mapping/layers.md). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
