The ground is talking. Lodeline lets you hear it. Lodeline is a field mapping and terrain-analysis app built for gold prospectors. Snap a geotagged photo of a creek, bench, gulch, or hillside and Lodeline pulls public 3DEP elevation data for that location, analyzes the surrounding terrain, and gives you a Paystreak Score: a 0-100 terrain favorability rating with a clear explanation of the features behind it. PHOTO → TERRAIN → PAYSTREAK SCORE See the ground differently. Lodeline uses LiDAR and elevation data to reveal terrain that can be difficult to recognize beneath trees and vegetation, including old channels, benches, drainage patterns, slope breaks, and other terrain features useful when researching prospecting ground. The Paystreak Score doesn't tell you where gold is. It helps you evaluate whether the terrain deserves a closer look and shows you the factors that influenced the score. AI GEOLOGIST: LODELINE+ Drop a pin anywhere and request an AI-powered field briefing for that location. The AI Geologist can: • Identify nearby documented historical mines from public USGS records • Show distance and direction to nearby historical mineral locations • Explain mapped geology and host rock • Analyze drainages, benches, slopes, and surrounding terrain • Answer follow-up questions about the location It combines Lodeline's terrain analysis with public geological and historical data to help you research a location before heading into the field. CORE FIELD TOOLS • Photo-to-terrain analysis • 0-100 Paystreak terrain favorability score • LiDAR and elevation terrain visualization • Topographic contours • Roads and public-land layers • PLSS grid • GPS waypoints • Trip organization • GPS track recording • Prospecting dig log • UTM and MGRS coordinates • Field-focused dark map interface LODELINE PRO For prospectors who want the complete field mapping toolkit: • Historical Mines: view documented public mineral records on the map • BLM Claims Lookup: open official BLM MLRS land records for an area • Offline Packs: download terrain and mapping data for use beyond cell coverage • Transect: draw an elevation profile across a creek, drainage, bench, or hillside • Unlimited waypoints and photos LODELINE+ Lodeline+ adds server-powered AI tools including the AI Geologist and AI Trip Planner. Lodeline Pro and Lodeline+ are optional upgrades. The core Lodeline terrain and field-mapping experience remains available without AI. BUILT FOR PROSPECTING: NOT PROMISES Lodeline does not detect gold and does not predict whether gold is present at a location. Instead, it analyzes terrain favorability using public elevation, geological, hydrographic, land, and historical mineral data and shows you the evidence behind its analysis. Historical mine records describe documented historical activity and do not indicate current mining claims, access rights, or permission to prospect. Always verify current land ownership, land status, mining claims, regulations, and access requirements with the appropriate authorities before entering or prospecting an area.

Favorability heatmaps refresh as you move the map. Improved animated map pills, organized Map and Layers controls, and Field Tools. Updated mining-claim lookup and clearer briefing details. Favorability describes terrain, not evidence of gold. Historical records are not proof. Verify current claims, ownership and access. ### 1.0.64 — 2026-10-20 Map and Layers is easier to scan, with clearer groups, display controls, and map credits you can open. Field Tools groups read as Capture, Measure, Explore this area, and Prepare for field. Stream Catcher is named in the menu. Map loading can show a short detail under the progress pill. Terrain favorability stays in a compact pill. Favorability describes terrain, not evidence of gold. Historical records are not proof. Parcels and claims are not permission to enter. ### 1.0.29 — 2026-10-15 Monthly, Annual, and Founders open the App Store purchase sheet again, including when Lodeline+ is already active. Rock ID saves a short report on this iPhone: what the specimen looks like, minerals it may be, and mapped geology of the area in plain language. It is a visual guess, not a lab assay. Delete your account in Settings, then Account. That removes the Lodeline account and cloud backup, and revokes Sign in with Apple. An optional note is kept without your name, email, or account id. Waypoints and photos on this iPhone stay on this iPhone. Catch score now shows Strong, Moderate, or Weak. That is stream-shape geometry, not a gold find and not the favorability score. ### 1.0.21 — 2026-10-08 A 30 second preview shows USGS LiDAR taking the trees off the canyon, then the map. Terrain favorability is a 0-100 read of the ground. It is not a gold finder, and it never shows a dollar value of gold. Ground Disturbance counts repeated pits in the terrain. When there are enough, you get one outline and a count. When there are not, it says nothing stood out. Those shapes can be natural. They are not proof of gold and not permission to enter. Closed beta tools now learn this account's beta grant from the server. Area Intel's privacy note says it sends the ranked stream reaches found there. ### 1.0.12 — 2026-10-07 No release notes. ## Apps similar to Lodeline | App | Rating | Price | Category | | --- | --- | --- | --- | | [California Roads](https://appshunter.io/ios/app/california-roads/id6755225750) | 5.0 (13) | Free | Navigation | | [Philadelphia Subway Map](https://appshunter.io/ios/app/philadelphia-subway-map/id6478450089) | — | Free | Navigation | | [3D Mappa - GIS & Topo Models](https://appshunter.io/ios/app/3d-mappa-gis-and-topo-models/id6479948679) | 4.6 (18) | Free | Navigation | | [Jus Charging Systems](https://appshunter.io/ios/app/jus-charging-systems/id6469570128) | 3.0 (4) | Free | Navigation | | [Montana 511 Traffic Cameras](https://appshunter.io/ios/app/montana-511-traffic-cameras/id6475734279) | 4.5 (266) | $2.99 | Navigation | | [Detector Maps](https://appshunter.io/ios/app/detector-maps/id6741421159) | 4.7 (263) | Free | Navigation | --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
