OS MapFinder

By Ordnance Survey Limited

Open iTunes to buy and download apps.


OS MapFinder is the first official iPhone/iPad/iPod Touch App from Ordnance Survey, enabling users to view, navigate and download the most up-to-date OS Landranger (1:50 000) and OS Explorer (1:25 000) maps of Great Britain in amazing high-resolution.

OS MapFinder is ideal for walkers, ramblers, runners, cyclists and generally anyone looking to enjoy the outdoors. The fast and easy to use App comes bundled with free overview mapping - including Ordnance Survey’s trusted and reliable 1:250 000 Scale mapping. The App allows users to quickly, and accurately, search by place name, postcode, and grid reference.

Ordnance Survey maintains Great Britain’s definitive digital mapping database, and with OS MapFinder users can enjoy the print quality of the trusted OS Landranger and OS Explorer maps (660dpi) on their iOS devices. The App allows users to buy and create their own bespoke high-resolution maps via Apple’s ‘In App Purchase’ service. Each mapping tile is fully downloaded to the iOS device, meaning that it will work anywhere regardless of iPhone/iPad signal. The tile download facility allows users to select and purchase up-to-date mapping of their favourite locations, and then easily plan, plot, record and review their own bespoke walks, runs and cycle rides.

OS MapFinder brings all the detail and reliability of the iconic Ordnance Survey paper maps to iOS devices.

Any 100 km2 map tiles purchased will be updated for FREE under a revision program. Tile updates are unlimited for the life of the application*.

Map tiles once purchased through your iTunes account can be uploaded onto all devices registered to that account (i.e. if you purchase on iPhone you do not have to repurchase on iPad). To do this, simply go to "Purchase" from the menu and then tap the sync symbol (to the left of the search). You will need to enter your Apple id and the app will start syncing.

Users who are having difficulty in finding purchased maps should make sure they are zooming in far enough. We will include a lock scale function on a future release.

*or until 31st March 2016 (whichever is longer), updates will generally occur bi-annually as we update our mapping.

Continued use of GPS running in the background can dramatically decrease battery life..

Ordnance Survey is committed to creating the best mobile mapping experiences. As part of this, we will be releasing regular updates to all our apps to improve their user experience and stability. We welcome your feedback and comments, and strive to act promptly on any complaints. Please get in contact with us via Twitter @OSLeisure, by phone on 08456050505

Customer Reviews

Excellent content

I'm really happy OS have made this app. I'll be visiting my home town of Bath next week and being able to get offline OS maps on my iPhone and iPad for hiking around the outskirts of the city is really great. Also having OS maps to plan with in advance is fantastic.

I'd love to see the overall app navigation simplified as it can be a little confusing in places. I think the use cases may need to be rethought a bit.

Also I'd make this 5 stars if you implemented iCloud sync of planned and recorded routes. I would like to plan routes on my iPad's big screen but take my phone with me on hikes.

Also I'm not sure why the app is 350+ megabytes. Surprisingly large?
