Peak Finder AR is a free Android app developed by TheFrenchSoftware. As the name suggests, it lets you locate mountains, peaks, and hills all around the world using augmented reality. With the help of your camera, the app shows you the name, height, and distance of over 800,000 peaks worldwide. Additionally, it displays the position of the sun, as well as the sunrise and sunset hours.

One of the most impressive features of Peak Finder AR is that it works offline, making it a great tool for outdoor enthusiasts. You can zoom in and out, check the GPS state, and adjust the orientation manually if needed. When you're online, you can access a 3D map that auto-rotates based on your location and displays topographic rendering. The app also gives you access to web photos of each selected peak and a wiki. Overall, Peak Finder AR is a comprehensive mountain and peak locator that is both easy to use and informative.
