Offline Maps & Downloads

Offline maps let the base map render with no connection — the other half of caching off-grid (the first half being offline cache sets). Most offline map capabilities are part of Cachly Pro.

Pro Offline Maps PRO

Cachly Pro’s offline maps are worldwide vector maps built from OpenStreetMap data and optimized for readability. Download them via the map-layers icon or Settings › Cachly Pro › Download Offline Maps. Maps update every two weeks. Features include:

  • Contours & hillshades as supplementary downloads, switching with your metric/imperial units.
  • Customizable layer visibility — trails, 3D buildings, points of interest — and 3D map rendering.
  • County lines & names for US states and comparable international regions — visible even at low zoom, so nearly a whole state’s county lines fit on screen.
  • Trail symbols & colors from OpenStreetMap, plus optional bold road color schemes designed to match UK Ordnance Survey styling.

Points of Interest & Their Icons PRO

Pro Offline Maps label points of interest with their own icons, colored by category — blue for transport, green for parks and outdoors, brown for culture and civic places, orange for food and drink, red for health and hazards, and so on. Here are all 129 POI icons you’ll see on the map:

Map Styles PRO

Beyond the POI icons, Pro Offline Maps draw roads, paths, water, terrain and land use with a consistent visual language, grouped by type below. Each swatch shows the element’s color and line weight at a typical zoom level (widths scale as you zoom in and out). Where the map would label a feature, the swatch includes an example name — road names in brown with a white halo, trail and path names in bold white with a dark halo, and route numbers in shields — drawn exactly as they appear on the map. The optional UK Ordnance Survey bold road scheme recolors the main roads; its variants are shown at the end.

Route Symbols PRO

Waymarked hiking and cycling routes are drawn from their OpenStreetMap osmc:symbol tag, which Cachly builds in different configurations: a trail colour for the route line, plus an optional route symbol made of a background shape and a foreground mark, each in its own colour. The symbols below are grouped by colour.

🚩
Trail distances. On Pro offline maps, Cachly also labels each waymarked route with its total distance, shown right alongside the dashed trail line — so you can gauge the length of a path at a glance.

When an offline map is active on the Live tab, Cachly can search map features completely offline, within your currently visible screen area — zoom to frame your target region first. Toggle it on under Settings; enable Allows Partial Words so searching “water” matches waterfall and waterway. There’s also a quick toggle right on the map: long-press the layers button and flip Offline Searching in the Options of the menu that appears — a checkmark shows its state, and the search field’s placeholder switches to Offline: Locations, Features, Coordinates so you always know which kind of search you’re about to run. For structured point-of-interest queries by OpenStreetMap tag (parking, drinking water, bus stops…), see OSM POI Search.

Downloading a Region

Choose a region to download; Cachly fetches it in the background (a background session keeps large downloads going even if you leave the app). The Downloads screen shows progress and manages what you’ve saved.

Download over Wi-Fi before heading out, and pair maps with an offline cache set so both the map and the cache data are on your device.

Custom Tile URLs

Adding a custom tile source: URL template in z/x/y format, TMS geometry option and presets like UK OS Maps.
Adding a custom tile source — URL template in z/x/y format, TMS geometry option and presets like UK OS Maps.

Beyond the built-in sources, Cachly can load tiles from any tile server — specialist commercial maps or free ones (many free servers require your own API key). Open the Map Types panel, scroll to Custom Tile URLs and tap Add Custom Tile URL.

On the Tile URL Details screen, give the source a name and enter its URL template in z/x/y format — for example https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png:

  • {z}, {x}, {y} — zoom level and tile coordinates (required).
  • {s} — rotates across the server’s subdomains.
  • {q} or {quadtree} — for servers that address tiles with a quadtree key instead of z/x/y.

Under Geometry, enable TMS / Flipped Geometry for servers whose y-axis runs the other way (TMS layout). A Presets section offers ready-made configurations — such as UK OS Maps — so common services need no manual setup. Saved sources appear in the Map Types panel like any other map, and can be edited or removed later.
