Offline map & timetable
Just like to let you know that Arrivo Transit free has this but its not working any more.
You can have real time data and offline google maps showing where all the bus stop are that is what arrivo has done.
If you do not do this then those who do not have on going data will be left out with out transportation help!
There is no app on google that provide this so i hope you can integrate it into your app.
There is another app called transittime which has real time and offline but it too has been abandon.
I will be willing to pay if you can make it happen its very important for all of us who do not have a permanent data connection. And it helps cause if you can't go online then offline helps!
