Northern Ireland is not included. The Isle of Man is included only at road-atlas scales.

Since 2010, Britain's national mapping agency Ordnance Survey has released a large amount of free map data. UK Map makes much of that data available in a single app. It includes 1:1M MiniScale® and 1:250k road maps, which are built into the app, and 1:25k district maps and 1:10k street maps for the entire country which you can download in 5km by 5km tiles. Unlike other Ordnance Survey apps, these downloads are entirely free of charge - the only cost is the initial purchase of the app. Once you've downloaded the detailed maps that you need, an internet connection is not required.

Note that Ordnance Survey have not released any of their Landranger® or Explorer® map data as part of this free scheme, so those maps are not included in the app. However the app's 1:25k maps are suitable for countryside use; they are comparable to Landranger, since they don't show field boundaries and a few other details. They do show water features and woodland, contour lines and hill shading, and most footpaths.

Because the footpaths are derived from volunteer-collected data from, rather than Ordnance Survey, the coverage is not yet as complete as the other map data.

The app can load GPX files (for example, from websites, other apps and from nearby devices via AirDrop) and display waypoints, tracks and routes. You can also mark waypoints and record tracks within the app, and export them.

You can view graphs of altitude or speed along recorded tracks and imported routes.

The app has a 3D mode that lets you view the terrain from any viewpoint, useful for visualising hills and mountains.

The app also includes a searchable gazetteer containing over 250,000 place names, 850,000 street names and 1.6 million post codes. All of this data is built in to the app, so this search also works when there is no network connection.

The app also supports the compass and GPS - on those devices that have them - to display your position, orientation and altitude.

What's New

Version 3.4

OS Open Map Local is now available as an alternative 1:10,000 map. Compared to the older OS Street View maps, these should be more up-to-date but they name fewer significant buildings. You can choose which to download, and if you download both a new settings switch determines which is displayed.

It's really good ...value, features, usability, reliability


I'm sold on this app. It used to be really good with great value access to maps at several levels of scale. Then they added a ton of route features. It took me a while to get my head around them but the support for this app is also exceptionally good. The route planning and recording does more things than I've had a chance to try out yet but all the basic things [plan a route then record a days cycling] I've done work well. I'm not loyal or anything. I recently looked to see if the competition from OS maps (or others) had anything to offer. Some of what OS maps is supposed to offer sounds really cool but if you read the reviews and look at the features and implementation.... I can't see why anyone would bother. I just think that when a small company gets so much right and continues to work to get better, it deserves to be acknowledged.

One of the very best


This was one of the very first apps I ever bought, maybe six or seven years ago. I couldn’t get enough of it then and showed it to everyone as a demonstration of what my iPad could do. In the last couple of weeks I have started to use all the route import, navigation and locational features. There is a lot there and it takes a bit of learning, but it’s stunned me again. Would still be value if it was ten times the price. Thanks developers xxxxxx

An Essential App.

Have used this App. extensively for a number of years now. I would find it difficult to live without it now. Nothing is 100% perfect, but this is close. After repeated warnings on the old version about iOS compliance, I am so pleased to see this new compliant version. It now also has a more intuitive interface. The map data is pretty accurate too, so no longer constantly buying OS maps, which is good!
