Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Treeline puts wilderness on the map. Explore and plan hikes, with beautiful topo maps, satellite imagery, and detailed information about trails, amenities, and points of interest, no connection required. While you have service, 20 more live data layers give you up-to-the-minute info on weather, active fires, and more.
Features:
- A beautiful, detailed, fully custom topo basemap inspired by NPS maps.
- 20+ layers, including public land boundaries, NPS maps, USFS and BLM roads, live weather, cell coverage, aircraft, historical mines and minerals, and bedrock geology.
- Combine and overlap layers however you want. Save presets to switch between different setups quickly.
- Record routes. Organize your saved routes and places, share them with friends, and customize them on the map.
- Navigate by foot and car. Build custom routes using any combination of modes, and save them to reference (or navigate) later. Preview elevation profiles in detail.
- Import and export KML, GPX, and GeoJSON.
- See an exact forecast for any point on the map.
- Generate viewsheds so you know what you'll be able to see from a peak or a campsite.
- Discover trailheads, campsites, water sources, landmarks, caves, and more. When you're back in town for a resupply, see grocery stores and gas stations.
- Download maps offline on demand.
- ...And lots and lots and lots of other cool stuff!
