How can I get an OS Maps App on my phone?

Ordnance Survey (OS) maps are available to preview on your phone using various apps and websites. The official OS Maps website allows you to preview maps and purchase map subscriptions for use on your phone or computer. Additionally, there are several third-party apps available for both Android and iOS devices that offer preview and purchase options for OS maps. These apps allow you to preview the maps and purchase access to them, either on a subscription basis or as a one-time purchase, depending on the app and its features. The following apps and websites have transformed the way we explore the great outdoors and provide the convenience of viewing maps offline and offer a selection of ready-made routes for users to explore.

It's worth noting that some apps may require an internet connection to access the maps, while others allow you to download maps for offline use. Additionally, some apps may require a subscription or a one-time purchase to access all of their features and maps.

MapServe®, which is aimed at professionals, provides limited free previews of OS maps. Our website contains the following OS mapping:

  • OS MasterMap®, the Ordnance Survey's main digital product which is a database that records every fixed feature of the United Kingdom that is longer than a few metres on a single continuous digital map. It is primarily used by architects, surveyors, planners, tree surgeons, and members of the public seeking to submit planning applications.
  • OS Overview map, a detailed map of the United Kingdom that acts as a backdrop map to OS MasterMap® and contains less information but is suited for large areas.
  • OS Road map, a small-scale map that provides a high-level overview of the United Kingdom's road network, from motorways to country lanes.
  • Historical OS mapping dating back to the nineteenth century.

One such tool is the "OSM-GB" layer, which provides a preview of OS maps in the United Kingdom within OpenStreetMap. You can access this layer by visiting the OpenStreetMap website and enabling it in the "Layers" menu. Once enabled, the OSM-GB layer will display OS maps within OpenStreetMap, allowing you to preview and explore OS maps within the OpenStreetMap platform.

Keep in mind that the OSM-GB layer is a third-party tool and may not provide the same level of detail or accuracy as official OS maps
