I created and published the mobile application software that shows the desired bus lines using the web services offered through the Istanbul Metropolitan Municipality Open Data Portal.

Information displayed about the selected bus;

📌 Current location (on the map)
📌 Door number
📌 Starting and ending stops
📌 Nearby stop
📌 Which direction is it going (last stop)
📌 Last position date
📌 Distance (if location sharing is on)

Updated bus data comes every 60 seconds, while the entire page is not refreshed. Only the map and the content of the information screen that opens, if any, change.

This is not the official app.
