The Istanbul public transport app: metro, bus and ferry in one place
MetroFlow brings the metro, Marmaray, trams, the Metrobüs, 773 İETT bus lines and the ferries of three operators into one app: minutes to the next departure, where the bus is, door-to-door directions with the fare, and a countdown to your stop while you ride. Rail timetables live on the device — it works in the tunnel. Free, no ads, no account; iPhone and Android.
What it does
Live
Next departure, minute by minute
Ferry, bus, metro: tap a stop on the map and the next departures appear. Bus positions come live from İETT; ferries and rail show the timetable next to live data.
Directions
Door to door, with the fare
Fastest, fewest transfers and least walking side by side. Full and student fares include transfer discounts; Metrobüs and Marmaray are priced by stop count. Where to board, where to get off, how far to walk.
On the way
Countdown to your stop
Start the journey: stops left, arrival time, transfer alerts. It keeps running on the Lock Screen and in the Dynamic Island — pocket the phone, it tells you before you get off.
Near me
Nearest stops and the next departure
Turn on location: metro, bus and ferry stops around you with distances, each with its next departure in one list. Favourite the ones you use; they stay on the home screen.
Widgets
Home Screen and Lock Screen
Your saved stop’s departures on the Home Screen; the next departure at a glance on the Lock Screen. Decide whether to leave now without opening the app. The Home Screen widget is open to everyone; the Lock Screen widget comes with supporting the app.
Offline
The whole network in your pocket, no data needed
26 rail lines, 300 stations, piers and the Metrobüs on a real map. Rail timetables live on the device: you see the next train in the tunnel and without data. Tap a line for all its stops.
Also
Alerts and cancellations
Metro İstanbul, İETT and Şehir Hatları notices in the app; ferry cancellations on stormy days are flagged separately.
English and Turkish
Full English interface: stop names, direction labels and notice summaries. Complete for visitors.
Free, no ads, no account
Departures, the map and directions are open to everyone; you can support it from inside the app if you like. No tracking, no sign-up, no subscription.
From the App Store
What it doesn’t do
- It does not show your İstanbulkart balance; use the İstanbulkart Mobil app for that.
- Live bus positions depend on İETT's feed; when it is down, the planned timetable is shown and labelled as such.
- Istanbul only.

Frequently asked
Is MetroFlow free?
Yes — no ads, no account, no tracking. Departures, the map, directions and live trip tracking are open to everyone. A one-off support purchase inside the app adds the Lock Screen widget and unlimited favorite stops and routes; the free version keeps three of each.
Is there an Android version?
Yes: Google Play. For iPhone, the App Store.
Does it work offline?
Rail timetables and the network map live on the device, so you still see the next train in the tunnel or without data. Live bus and ferry positions need a connection.
Is it in English?
Fully. The interface, station names and notices are in English; official operator notices are summarised in English.
Does it show İstanbulkart balance?
No — that needs the official İstanbulkart Mobil app. MetroFlow shows the fare of every route so you know what will be charged.
