Integrate offline maps in App

I’m working on a project where we are developing an iPhone-/Android-app in which we would like to be able to integrate offline maps for a specific area. We would then like the user to be able to use the GPS within that area, to be guided from where he is - to a specific point (within the offline map). All this without having an internet connection. Would this in any way be possible with OpenStreetMaps?

Indeed this should be possible!

Have a look at the OSM wiki about and

Try filtering the apps that are a) open source and b) use offline maps

Then tell us what app comes near your aims.
