Masir is a complete guide to the Tehran Metro: every line and station on a real street map, the nearest station to wherever you are, offline train timetables, step-by-step routing, station exits and live service alerts — all in one free, lightweight app.

Underground, a signal is a matter of luck, not a given. Masir doesn't rely on it: the city data pack downloads once, and after that you can check the next train time with no internet connection at all.

■ The Tehran Metro on a real map (new)

See every metro line and station drawn over the city's streets, and switch to satellite view with one tap — so you can tell which side of the road the entrance is actually on. Tap any station to open its line, exits and timetable.

■ The nearest station to you (new)

Tap the locate button and the map centers on you, showing the stations around you. GPS is requested only at that moment, only with your permission, and only while the map is open. Your coordinates stay on your phone and are never sent to any server. Decline it and the rest of the app still works in full.

■ Step-by-step Tehran Metro routing

Pick your origin and destination and Masir finds the fastest route, accounting for line-change time, the walk between platforms, and each line's real headway. Direction of travel and every transfer station are laid out step by step.

■ Offline train timetables

The full schedule for all 7 Tehran Metro lines and their branches is stored on your phone. See how many minutes until the next train and which platform it leaves from. Thursdays, Fridays and public holidays have their own timetables.

■ Every station in detail

Over 150 stations with maps, a full list of exits with names and addresses, interchange stations, and stations that haven't opened yet — so you never come up the wrong staircase.

■ Clear accessibility info

Filter stations by elevator and step-free wheelchair access. Water fountains, toilets and ATMs are each marked with three honest states: available, not available, unknown.

■ Service alerts

Get notified about station closures, delays and changes to operating hours — only for the lines and stations that matter to you.

■ Branch lines, made simple

Which platform does the Parand train leave from, and how often does it run? Masir answers before you board, not after you get off at the wrong station.

■ Light, free and privacy-respecting

The city data pack is under 1 MB. No sign-up, no account, no intrusive ads. Your location is never tracked in the background, and never stored or transmitted.

How the offline mode works

You download the city pack once. Station search, timetables, "next train: 3 min" and station details all work with no connection. Routing, service alerts and the street and satellite map tiles are fetched over the internet — so the city map needs a signal, but the train times don't.

If you're looking for a Tehran Metro map, metro lines on a city map, subway timetables, a metro route planner, or the nearest metro station to you, Masir is the app you'll actually use on the platform every day.

Requires Android 8.0 or newer.
