Location Testing Utility for Android — no root required.
Patch any app to use custom GPS coordinates with a single tap.
Patch & Spoof — Select any installed app, patch it with location hooks, and assign custom GPS coordinates. The patched app sees your chosen location across all Android location APIs.
Map Picker — Interactive full-screen map with Google Maps tiles, search bar, satellite/street toggle, and crosshair targeting. Search by address, coordinates, or Google Maps URL. Tap to save locations with custom names.
Saved Places — Build a library of GPS locations. Assign any saved place to any patched app instantly. Each place stores coordinates, accuracy radius, and reverse-geocoded address.
Per-App Control — Each patched app gets its own location assignment. Switch between saved places or revert to real GPS on a per-app basis.
Visual Patching Timeline — Watch the multi-step patching process (parse, patch, install) with a clear timeline UI and color-coded status updates.
Comprehensive Hooking — Intercepts LocationManager, FusedLocationProviderClient, GNSS satellite data, WiFi scan results, and cell tower APIs. Includes realistic GPS jitter, satellite simulation, and anti-detection bypasses.
Material You — Dynamic color theming with seed color picker, dark/light/system mode, and Material 3 Expressive components throughout.
PhantomLTU uses LSPatch technology to inject location hooks into target apps at the APK level:

Once patched, the app's location APIs are intercepted at runtime:
LocationManager—getLastKnownLocation,requestLocationUpdates,getCurrentLocation, provider queriesFusedLocationProviderClient— Google Play Services location (Tasks, LocationResult, LocationCallback)GnssStatus— Simulated satellite constellation with realistic PRN, elevation, azimuth, and SNR dataTelephonyManager— Cell tower location queries blocked to prevent triangulationWifiManager— Scan results cleared to prevent WiFi-based positioning
All spoofed locations include micro-jitter, GPS noise, and realistic metadata to appear as genuine GPS fixes.
Clean Architecture with MVVM. Three layers — presentation depends on domain, domain has no dependencies, data implements domain interfaces.
