Horrible

Dont even bother downloading it unless you live in the UK. I live in California but fly to London and take heathrow express more than 20 times a year but this app wont let you register unless you live at a valid UK post code. So.... Pointless for non UK residents

Oh.. And app has been updated only once in more than two years.. So dont bother..just like they didnt bother.
