Great Great app, suggested improvement - some things are blocked by the large Zoom Out and In buttons, would be better if these weren't there, or could be turned off. Can't see the key in the bottom right..
Excellent App I am red/green colourblind and find that I am often unsure of which line I am looking at when viewing the normal tube map. This app solves that problem. I would like pinch to zoom functionallity rather than plus/minus but that is a minor point.
Cool New app
