Memory Map

Memory Map Transforms Your Android into an Offline Navigation Powerhouse

Stop losing signal right when you need directions the most. Memory Map by Joan Zapata turns your Android device into a fully autonomous, offline-capable navigation system that functions reliably even in the most remote wilderness areas, deep underground, or during international travel without a data plan. This is not a cloud-dependent map viewer—it is a complete, preloaded cartographic toolkit that lets you browse, mark, and navigate through high-resolution topographic and road maps without any internet connection whatsoever.

Core Features and Navigation Tools

The application loads vector and raster map files directly from your device's internal storage or SD card. You can import popular map formats including MBTiles, SQLite, GeoPackage, and OSM XML—no conversion, no proprietary containers. Once imported, every tile, every contour line, and every labeled road remains fully interactive offline. The built-in map renderer supports dynamic zoom levels from 1:100,000,000 down to 1:1,000, giving you both global context and street-level detail without stuttering or reloading.

For location tracking, Memory Map leverages the Android GPS sensor hardware directly. You see your real-time position plotted as a blue dot on the offline map, with a live compass heading indicator showing your facing direction. The app also records a visible breadcrumb trail of your movement path, which you can export later as a GPX or KML file for sharing or archiving. The waypoint system lets you drop custom markers with editable labels, color-coded icons, and optional altitude notes—perfect for logging campsites, trail junctions, or points of interest during field surveys.

The measurement tools are particularly robust. You can draw straight-line distances between any two waypoints, calculate the total length of a multi-segment path, and even measure the area enclosed by a polygon route. All measurements display in metric or imperial units, and the app saves them alongside your map session for later reference. For navigation planning, the route builder accepts a series of waypoints and then traces a path along existing roads or trails, displaying cumulative distance and estimated travel time based on configurable walking or driving speeds.

• Offline Map Import Engine – Loads MBTiles, SQLite, and GeoPackage files directly from storage without any cloud dependency or account requirement.
• Live GPS Tracking with Compass – Displays your real-time position and heading on any offline map, with automatic breadcrumb trail recording.
• Advanced Waypoint and Measurement System – Drops color-coded markers, calculates distances and polygonal areas, and exports all data as GPX or KML files.

Key Advantages for Reliable Navigation

Memory Map prioritizes battery efficiency and storage optimization. The map rendering engine uses hardware-accelerated tile caching, so scrolling and zooming remain smooth even on mid-range Android devices. The app consumes zero mobile data because it never attempts to fetch tiles from the internet—every pixel on screen comes from your preloaded files. This makes it ideal for long hiking trips, backcountry skiing, geocaching expeditions, or any scenario where cellular coverage is unreliable or unavailable.

The user interface follows Material Design principles with a clean, dark-mode-compatible palette that reduces eye strain during nighttime use. All critical controls—zoom slider, layer switcher, GPS lock button, and waypoint manager—remain one tap away, never buried in nested menus. The app also supports multi-touch gestures for rapid map manipulation, including pinch-to-zoom, two-finger rotate, and long-press to drop a waypoint.
