Keeping it Real

this has to be my most used App, total intel on the status of the tube and route planning. Best feature has to be the live departure boards, great for seeing exactly when the next train will arrive, and its always spot on!
Bit slow to update sometime, loads up with yesterdays tube status until it refreshes which can be a bit of a pain, especially if you, like me, are mostly using this app whilst walking up and down stairs, and glancing at the app. Would be nicer if it did not display anything if its out of date.
The locate function looks awesome, have not had a real world reason to use this yet, but it will tell you the closest tube stations and the next trains. It also has a link to google maps for this feature, so you can guide your there.
Best extension to this app for me would be the inclusion of rail info also, living in sw19, the train is often as fast as the tube for getting around, but for that we have to switch to the £4.99 national rail app.
