We've got them for buses but now you can see exactly where your tube is too. No more waiting to hear about delays when you get to the station, no more getting to the station and realising you are waiting for the only train that's going to take 8 minutes to arrive that morning.
Check out the live tube app and spend a little more time above ground rather than under ground by timing your entry to the station platforms just right. Let's face it, humans aren't really meant to be underground until we reach the inevitable so why idyl down there longer than you have to?
Look at the app and see where every tube train is in real time- all the time. Fun right? Plus if you squint a bit they kind of look like the little pac-man ghosts.
