About this app
Made for a clear purpose.
Geopurl: Offline Map Lab is a focused, fully on-device app. A native GeoPackage and MBTiles field workbench for inspecting layers, tile pyramids, attributes, bounds, coordinate metadata, and offline map-package health.
KEY FEATURES - Open GeoPackage and MBTiles containers from Files - Inventory vector, raster, tile, and attribute tables - Inspect zoom coverage, bounds, CRS, and row counts - Preview bundled offline vector and raster layers - Export a package-health report without uploading data - Complete bundled sample and local comparison workflow - Local PDF report and Apple system share export - Original offline technical reference library
ONE-TIME AND PRIVATE - One paid download; no subscription or in-app purchase - No account, advertising, analytics, tracking, or developer-operated backend - Core features and bundled content work offline - Work remains on device unless you deliberately share or export it through an Apple system interface
Inspection and field-review aid only. Confirm survey control, CRS transformations, topology, and authoritative source data in approved GIS software.
