The idea of having access to them offline seeme good. Downloading this app killed the rebooted extension on my hosts wifi, it is so heavy. But BUS ROUTES? Not a chance. You go to bus and you get a list of bus stops starting with "A"... You type in an address and the local bus stops come up. But Pariss BUS ROUTES are complex. They dont have, for example, a Rue Raspail bus. You need the bus numbers, where they meet so you can change. You need to see their ROUTES. Here, you can destroy your hosts wifi extension, but a BUS ROUTE map? Which it says it had? Naaaaaah. Nothing even close. Terrible, horrible, mindless app. Clearly whoever designed it had no idea regarding how a person might want to use it. None.
