Make the app then license or sell it to the bus company? I am in the exact same boat, at my university. Actually, a couple years ago I started making an iOS app too for bus timetables but never finished because after a couple months of development google added the city's routes to google maps. Does google maps not have your city's routes? I'd be interested in helping out. Also I thought that was one screenshot linked and I got this: "https://i.freeih.com/7278/iphone_screenshot.png%20https://i.freeih.com/7279/iphone_screenshot_3.png" https://i.freeih.com/7278/iphone_screenshot.png%20https://i.... and was quite confused...
