Unterra turns the real world into your personal canvas. Explore your surroundings to uncover the hidden paths on your map. Discover hidden streets, record individual trips, see your driving heatmap, track streaks and statistics, and trace the path of your life in high detail.
Unterra is built privacy-first. Your GPS location stays on your device, powering your map and your stats and nothing else. We never collect, store, sell, or share your GPS data, and we never track where you have been.
Whether walking, cycling, or driving, Unterra gamifies your journey and records every single path you traverse.
Start with a completely covered map. As you travel, your path acts as a spotlight, permanently revealing the geography beneath. See how much of your city remains undiscovered.
Using local city databases and high-performance boundary servers, Unterra detects when you enter new cities, states, and postal codes, logging your progress automatically.
Missed a path or imported old travel data? Use the Pro pencil and eraser tools to draw and manually clear or cover custom sections of the map with full size and radius control.
Push your boundaries further. Unlock milestones for total mileage, cities uncovered, percentage exploration, and country borders crossed to earn premium sharing badges.
Snap a photo while you explore and Unterra drops a pin for it right where you took it, automatically grouping nearby shots so one stop reads as a single memory.
Glance at your home screen to see your last explored spot and how much of the map you have uncovered, no need to even open the app.
Switch the map to Heatmap mode and every path you have traveled lights up by how much you have used it, red where you go constantly, blue where you have barely passed through.
Experience the core concept right here. Move your cursor or drag your finger over the foggy map to the right. Witness the landscape reveal itself in glowing detail as you explore. That's the feeling of taking back the map!
Drag the slider and watch your exploring unfold in seconds, every road revealed exactly when you found it.
Unterra is always quietly revealing the fog wherever you go. Now you can also hit record and capture one specific drive, with its own roads, its own stats, and its own page in your history, instead of blending into your all-time totals.
Every day you explore adds to a running streak, a full activity calendar, and two live trend charts tracking how much area you have revealed and how far you have traveled, so months of exploring add up right in front of you.
The app logs and lists your stats directly, building a personal database of your travels. Watch your statistics grow as you roam the planet:
