Nearest Tube for iPhone 3GS and iPhone 4 on the iTunes App Store. Tube Exits for the London Underground - Save Time. Beat the crowds. g2 tube stations. Apple iPhone Development. Tube Deluxe at Malcolm Barclay. Since I had an overwhelming response from Tube Status, mostly for a Map, I built and released Tube Deluxe (iTunes link).
It’s something I could not do for free as the map is copy right protected and needs to be licensed from Transport for London. I’ve also put a lot of development effort into Deluxe and it is actively maintained.
