The OS OpenSpace SDK (software development kit) enables you to create free and commercial mobile applications with our data. It provides access to a number of mapping layers and gazetteer lookups and is available for iOS and Android.
The OS OpenSpace SDK for iOS has a similar API to Apple's Mapkit, so that moving from Apple mapping to Ordnance Survey mapping is simple.
With the OS OpenSpace SDK for Android, it is very straightforward to migrate from MapKit to the Ordnance Survey API with only a few changes to your application required.
