Finally of line routing for ubuntu touch! OSMScout
Nice app which is free or small £2 fee for support
I installed from the app store and just installed the UK map. This app has re-route function and route from bike or car. The developer has had problems adding the download location to the SD card as some of the maps are like 1 gig, but there are work arounds and im sure this will get sorted soon, basically down to security. This is one of the reasons i dual boot on the nexus 7 for navmii on the android side, im getting closer to dumping dual boot on the nexus 7 as soon as i get some remote desktop and mouse support. This is the type of app the developer wants a pat on the back for. Awesome.
