New: arrival alarms. Pick a station and how many minutes of warning you want, and csuki tells you in time, even with the app closed.
csuki is an independent public transport app for Bucharest, Cluj-Napoca, Constanța, Iași, Timișoara, Budapest and Chișinău. It shows the trams, trolleybuses and buses that are actually running, right now, and how long until one reaches you.
csuki is not affiliated with, endorsed by, or an official app of any government authority, municipality, or public transport operator.
CITIES
• Romania: Bucharest (București), Cluj-Napoca (Kolozsvár), Constanța, Iași, Timișoara (Temesvár)
• Hungary: Budapest
• Moldova: Chișinău
THREE WAYS TO SEE THE SAME TRAFFIC
• 1D list — the line as a list of stops, each with the minutes until the next vehicle reaches it.
• 2D map — the same line drawn on the map, every vehicle in its real place.
• AB planner — say where you are and where you are going, and csuki builds the journey out of the vehicles currently on the road.
One button switches between them.
THE AB PLANNER STAYS WITH YOU
Most planners hand you a plan and forget you. csuki keeps yours alive for the whole trip:
• It plans with the vehicles actually running, not with a timetable.
• If an earlier vehicle on your line would get you there sooner, it offers the swap.
• If your connection leaves before you can reach it, the times move to the next one instead of quietly going wrong.
• If the vehicle you were following stops being tracked, csuki says so rather than pretending.
• Set A to your location and B to home, save it as a favorite, and loading it anywhere plans the way home from wherever you are standing.
MORE
• Vehicle numbers — every vehicle shows its plate or fleet number, on the map, along the line and in the arrival times.
• Wheelchair access — vehicles that take a wheelchair are marked, wherever the operator provides this information.
• Arrival alarms — pick a station and how many minutes of warning you want, and csuki notifies you before the vehicle gets there.
• Favorites — store a line, its direction and your view, or a whole AB journey, and load it in one tap.
• Choose how much traffic you see — only your route, the line's alternative routes, or every line that shares a stop with you. The arrival times follow your choice.
• Official timetables — tap a stop name to open the operator's timetable where the line has one.
• Tap any stop for its next arrivals.
• A light and a dark theme.
• Eight languages: English, Romanian, German, Hungarian, Russian, Ukrainian, Italian and Spanish.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
- Lines, cities and settings stay up to date even if you never close the app: changes reach you within four hours
- New first hint: the station dots show the first arrival time. All hints now sit at the bottom, below the arrival times, and are shorter while an ad is shown
- A line opened for the first time starts zoomed in, so the station dots show their times
- A city or line that is no longer offered takes you back to the list and switches its alarm off
- Fixed: the arrival times of the stop under the arrow could disappear while an ad appeared, or cover the line's header
