GPS tracking for every session.Find logging with photo and audio.Permission Vault for landowner records.

Each landowner permission stores name, contact, approval status, expiry date, and the site boundary drawn on the map. The Vault shows which permissions are active, expiring, or expired. A PDF permission letter can be generated for any landowner, and expiry dates can be added to the phone's calendar with one tap. Combined with Perimeter Guard, the phone vibrates near the boundary edge and plays an audio alarm when it is crossed.

The app overlays genuine USGS historical topographic tiles onto modern satellite imagery. Old homesteads, schools, churches, roads, and settlements that may no longer appear on current maps become visible on the historical layer. Those locations often produce finds because they were inhabited; many are now undeveloped ground. Opacity is adjustable to blend the two layers. Coverage is best across the United States.

The Detecting Forecast pulls weather data and generates a 0-100 Detecting Score with a verdict: Excellent, Good, Fair, Poor, or Bad. The score factors in soil moisture (wet soil conducts target signals deeper), wind speed, temperature, humidity, and precipitation. Available for any location, up to seven days ahead. Tips explain why conditions favor or hinder detection.

Three ways. The Coverage Heatmap renders a color-coded density overlay of the current session: green indicates light coverage, red indicates concentrated coverage, blank indicates none. Track Overlay loads past sessions onto the live map so previously covered ground is visible. Session Comparison stacks 2 to 5 visits to the same area to highlight uncovered ground.

Tap the map to drop points and measure distance along a path with per-segment labels. Tap point 1 again to close the path into a polygon. Perimeter and area are calculated in hectares or acres using spherical geometry. Vertices are draggable, measurements can be saved to the Library with a reverse-geocoded name, and any polygon converts to a Perimeter Guard boundary in one tap.

Tap the Find button to drop a GPS-pinned marker. Choose one of 6 types (Treasure, Gold, Coin, Relic, Jewelry, Trash), set depth on a 0–40 cm slider, and optionally add a name, value, weight, notes, photo, video, and audio note. Every field is editable later. The Media Gallery groups photos, videos, and audio by session, and Find Search filters across sessions by name, type, or notes.

SweepTrack Pro is a GPS tracker and field toolkit, not a detector controller. It works alongside any metal detector. The app includes 60+ preset templates across 12 brands (Minelab, XP, Nokta, Garrett, Fisher, Teknetics, Bounty Hunter, Quest, White's, Tesoro, Detech, Rutus) plus a Custom slot for user-defined settings. Up to 10 configurations can be saved and shared via JSON export or QR code.

Free includes GPS tracking on all 3 base map types (Street, Satellite, Terrain), unlimited sessions, unlimited finds, 1 detector preset, 2 Permission Vault entries, 3 themes (Tactical, Amber, Cobalt), and core field tools (compass, ruler, back-to-start line). Pro adds: unlimited presets and Vault entries; Measure tool, Track Overlay, Coverage Heatmap, session comparison and merging, Perimeter Guard, USGS Historical Topo overlay, offline tile downloads, Detecting Forecast, NOAA tide tables, Cloud Backup, Night Vision, Coin Caliper, all 12 themes, and full export. Pricing: $19.99/year or $3.49/month with a 7-day free trial.

Yes. Download map tiles in advance — Street, Satellite, Terrain, and USGS Historical Topo are all available for offline use. GPS tracking runs on the phone's hardware and requires no internet connection. The features that do require a connection are the Detecting Forecast, NOAA tide tables, and Nearby Sites lookup.

All data is stored on the device. No servers, no analytics, no ads, no third-party tracking. The optional Google Drive backup writes an encrypted copy to the user's own Google Drive account; SweepTrack Pro has no access to that data. Export to GPX, KML, CSV, or SweepTrack JSON is available at any time.

Active GPS tracking uses approximately 10–15% battery per hour, comparable to Google Maps in navigation mode. A power bank covers a full-day session. On Xiaomi, Samsung, OnePlus, and other devices that aggressively limit background apps, SweepTrack Pro detects the manufacturer and shows the exact battery setting required to keep tracking running with the screen off.

Yes. The first-launch tutorial covers tracking, map controls, history, statistics, and other features across five slides. The Free tier includes unlimited GPS tracking, sessions, and finds. The Guides section of this site contains 30+ articles covering both the app and the hobby.

Not yet. SweepTrack Pro is currently Android-only. iPhone support is being evaluated but isn't on the roadmap with a release date. Join the launch list to be notified if and when an iOS version becomes available.
