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). The optional UK Ordnance Survey bold road scheme recolors the main roads; its variants are shown at the end.

Trail waymarks 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 waymark symbol made of a background shape and a foreground mark, each in its own colour.

Offline map searching PRO
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. 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.
Custom tile URLs

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.
Other formats Cachly handles include MBTiles (with local tile search) and DeLorme PRO.
