The Istanbul metro map, no bells, whistles, or other complications. From the official Türkiye Devlet Demir Yolları (Turkish State Railways), you can zoom the subway map in, zoom it out, and that's all. Very simple and easy to use! Opens to the Istanbul map immediately so you can quickly decide if you need to hop on the train in front of you or wait for the next one. The app size is minimal for a quick download regardless of network speed.

This app is excellent for Istanbul visitors and longtime residents alike.
