MapFinder for Android

By Ordnance Survey Free

Developer's Description

OS Maps'. The OS Maps app also allows customers to download a digital version of their paper map, and view and subscribe to see all of the GB Ordnance Survey maps.

OS Maps won the Digital Product of the year 2017 by the Outdoor Industry Association.

Please note: OS Maps and The MapFinder are not compatible and therefore purchases cannot be transferred between the apps.

OS MapFinder is a large download. With it, you can search our 1:250 000 scale road map by place name, postcode or address. You won't even need an internet connection to search as it also works offline. Then, via the in-app options, you can buy the OS Landranger (1:50 000) and OS Explorer (1:25 000) close-up maps of the areas you'd like to focus on - and after purchase, those maps will always be available on your device too.


Plan your route in advance using our route-planning tools, or track your location (with your phone) using the integrated GPS. Discover Britain's hidden treasures, things like historic monuments and mountain peaks, or just go for a ramble and use the map to discover more of the landscape. See how long it will take on average to walk your favourite routes - plan, plot and review your own walks, runs and cycle rides, knowing you have the features and reliability of our Explorer and Landranger paper maps to hand.

Ordnance Survey maintains Great Britain's definitive digital mapping database. With purchases made via OS MapFinder, you'll have access to high-resolution map tiles that work anywhere regardless of signal.

- A free overview of Great Britain at 1:250 000 scale

App and Map sizes

The app is a large download. It has to save the maps and search database to your device. Please make sure your device has enough free space and you're connected to a stable WiFi point before starting the download. The purchasable map sections are around 60MB each. If you want to save space, you can remove a purchased map section from your device, and then download it again (free of charge) when you next need it.

Map Updates

We will no longer be issuing updates to map tiles, but you will be able to continue to use any current tiles you have purchased.
