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.
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..
It's very hard to explain what being "colour blind" is like to people who are not. But the tube map makes it real easy. When I look at it - I think "why on earth did they decide to make some of the lines the same colour?". It's not a minor curiosity, it makes it almost useless to me. But this app fixes it, utterly and completely. Thanks and bravo! By the way for every 20 white males you know. One of them has the same type of color vision deficiency as me - called deuteranomaly. So this is actually a nuisance at a societal level. Unless you hold certain political views that is :-)
Cool New app
