For the Londoners (or those visiting) - Tube London City is out. It's a bit pricey I think for what it does - at £6 (or $18) it's perhaps not the best of price points to pick. Maybe £3 is a better target. BUt, it does have some of the most useful features all in a visually attractive package I think. Journey planner, zoomable maps, tube line updates (though not as good looking as TubeStatus app) and station info. I hope TfL can get their act together and develop a more full featured app with oyster card top-up access and departure board info. Developer's demo video is on website: http://visualit.co.uk/Apple/iphone.htm To locate app try Going to "Navigation" category of the itunes App Store (desktop version, iphone version for some reason doesnt pick it up yet) - you'll find it there on Page 1. For some strange reason, it takes a while fore new apps to link up to the itunes search engine.
