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. As the free O.S. data does not include footpaths, this app superimposes footpaths derived from volunteer-collected data from These downloads are free of charge.

In addition to the free maps, you can also purchase and download 1:50,000 and 1:25,000 maps that are just like the Ordnance Survey paper maps. You can also purchase 1:10,000 maps for selected urban areas which show more detail than the free 1:10,000 maps.

Once you've downloaded the detailed maps that you need, an internet connection is not required.

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, plan routes and record tracks within the app, and export them.

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

Now got to be the best UK OS tracking map app available.

I have used this app for many years since it was first conceived and never been let down in any shape or form. The updates have always improved the app with new features. The only part missing was plotting a route so had to export / share the gpx file from one app to this one (easy enough but messy for corrections to a planned route). Now with the latest update I was so happily surprised to find that route plotting is available. Which works exceptionally well. I could not be happier, well done developers and thank you. Various other bits and pieces have been improved as well. With out doubt this must now be the best UK OS mapping application for walking / hiking / biking available. The file system does need a little getting used to but you will not be disappointed with this navigation app. Just remember to touch the "FILES" tab at the top to get to the main files menu list then work from there. Thank you developers keep up the good work.

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.

Best £8 I have spent on an app

After initial layout (£7.99) for this app, I was expecting to pay for each detailed OS map I might want in addition. As it turned out, there are free maps available and the 1:10,000 version is perfect if you are looking to find places to walk anywhere in UK. Bridleways, footpaths etc are all well detailed on the free maps. After living in my area for 20+ years we’ve found places to walk that we would never have otherwise found. Not sure what the paid maps offer in addition yet but I may download one just to check what else is included. Not sure what they actually cost as the prices don’t seem apparent. All in all - a fantastic for wannabe walkers & local explorers. Note: A trip to Scotland proved the path and bridle-way details are not complete or not detailed as I have experienced in England and Wales.
