Citymapper

Review by eFreeware

If you live in a city where getting around means switching between a subway, a bus, a rented bike and your own two feet, Citymapper is built for exactly that. It pulls those options into one place, compares them in real time and then walks you through the trip step by step. The developer, Citymapper Limited, has been refining this idea since the app first appeared in April 2013, and it now lists more than ten million installs with a 4.8 average from over 387,000 ratings.

What that gives you is a single app for the question every city dweller asks several times a day: what is the fastest way from here to there right now? Instead of checking a transit agency site for the next train and a separate app for bike share availability, you get one comparison and one set of directions. The appeal is strongest for people who already use public transportation regularly and want it to feel less like guesswork.

It is free to download and carries ads, with in-app purchases also offered. That combination is worth knowing before you install. Beyond that, the value on offer is mostly in the routing and the live information layered on top of it.

One comparison across every way of moving

The core of the app is a route planner that weighs buses, subways, trains, ferries, cabs, ride share, car share, bike share, e-scooters and plain walking against each other. You are not choosing a mode first and then asking for directions; you ask for the trip and the app shows you how the modes stack up. That is a meaningful difference for anyone whose best option changes with the weather, the time of day or how much they are willing to spend.

Once you pick a route, the GO button turns it into turn-by-turn guidance. The developer says this covers transit, walking, cycling and scooter trips, so the same interface carries you from a train platform to the last few blocks on foot. Three map views are available, which matters more than it sounds: a transit rider watching stops go by wants a different picture from someone following a bike lane.

The planner also handles some of the smaller logistics. It shows charge levels for e-scooters and e-bikes nearby, so you can judge whether a vehicle will get you where you are going, and it routes around no-parking zones. Those are the details that decide whether a shared scooter is a practical choice or an annoyance, and folding them into the route rather than a separate app is the sensible approach.

For the shared and hailed options, the app works with a long list of partners, among them Uber, Lyft, JUMP, Lime, Bird, Spin, Skip, Scoot, Citi Bike, JerseyBike, Bluebikes, Indego, CaBi, Divvy, Metro Bike, Breeze, Bay Wheels, Healthy Ride, Relay, BCycle, SA Bike Share, GREENbike, Grid, RTC Bike, BIKETOWN and Biki. It can compare cab fares and hand you off to hail a ride, so the comparison stage and the booking stage sit close together.

Live timing, alerts and platform-level detail

Where Citymapper earns its keep for daily riders is the live layer. It shows wait times and ETAs, and tracks buses, trains and ferries as they approach on a real-time map, so you are watching the vehicle rather than a timetable. Missed connections are the main frustration of transit travel, and this is the feature aimed squarely at them.

The station-level guidance goes further than most people expect. The app indicates which train car is best to board, tells you the next stop, alerts you when it is time to get off, and points you to the best exit at a subway or train station. If you have ever surfaced three blocks from where you wanted to be, that last detail is the one you will notice most.

Updates can also reach you on the lock screen, covering real-time bus arrivals, subway, ferry and train times, along with disruption, delay and status alerts and alternative routes when something goes wrong. You can save Home, Work and the stops and stations you use often for quicker planning, and subscribe to a specific subway, train, bus or ferry line so those alerts arrive without you asking. Sharing a live trip lets friends follow along and see when you will arrive, and any location or address can be sent with a single tap so the other person can get directions.

Two extras round out the package. Official subway and bus maps for cities including New York, Washington DC and San Francisco can be accessed offline, which is useful when you are underground or out of data. And on Wear OS, hitting GO in the app brings the trip information you need onto your watch, so you can keep your phone in your pocket while you travel.

What the app asks of you

Citymapper is free to download, and it carries ads. In-app purchases are also available. That is a trade-off to weigh before committing.

The app is built around supported cities, with a long US list that includes New York City, Chicago, Los Angeles, San Francisco, Washington DC, Boston, Philadelphia, Seattle, Miami, Atlanta, Portland, Denver, Baltimore, San Diego, Minneapolis, Houston, Phoenix, Dallas, Las Vegas, Pittsburgh, Honolulu, Salt Lake City, San Antonio, St. Louis, Cleveland and Austin, plus many more worldwide.

Its information comes from open data published by transit agencies, among them MTA, CTA, LA Metro, MBTA, WMATA, SEPTA, NJ Transit, Muni, BART, King Bus, MARTA, LIRR, RTD, TriMet, Metro-North Railroad, PATH, Houston METRO, San Diego MTS, Miami-Dade Transit, Metro Transit MN, METRA, RTC, TheBus, Port Authority, DART, AC Transit, Sound Transit, UTA, OCTA, VIA, PTD, St. Louis Metro Transit, RTA, Capital Metro, Broward County Transit Division, NY Waterway Ferries and LBT.

The most recent update, from September 29, 2026, reworks live updates and the step-by-step guidance, which suggests the developer is still investing in the parts riders rely on daily.

Getting the most from it day to day

The setup that pays off fastest is saving your regular destinations. Home, Work and your usual stops and stations remove most of the typing from a daily trip, and subscribing to the lines you actually ride means delay and disruption alerts come to you rather than requiring a check. If you commute on one train line, that subscription is the single most useful thing in the app.

For unfamiliar trips, let the comparison do its job before you commit. Looking at the full spread of options, including walking and shared bikes, often surfaces a route you would not have considered, and the fare comparison for cabs and ride share is worth a glance when you are deciding whether to spend. Once you are moving, the get-off alerts and exit guidance are the features to lean on, particularly in stations you do not know.

The offline maps are worth having ready before you need them, and sharing a live trip before you set off saves the messages asking where you are.

If you wear a Wear OS watch, starting the trip with GO on the phone and then relying on the watch keeps the guidance visible without holding anything. That is a small thing that adds up over a daily commute.

A planner for people who already ride transit

Citymapper is at its best for someone who lives in a supported city and already uses public transportation as their main way of getting around. For that person, the combination of live arrival times, disruption alerts, platform and exit guidance and multi-modal comparison covers nearly every decision a trip involves. The lock screen updates and line subscriptions turn it from something you check into something that tells you.

It is less obviously suited to people who drive everywhere or who live outside the covered cities. The app is built around transit, walking, cycling and shared vehicles, so its strengths simply do not apply where those conditions are absent. That is a question of fit rather than quality.

The presence of ads and in-app purchases is the main caveat for anyone who dislikes either. Otherwise, the app's case is straightforward: it answers a question city residents ask constantly, and it answers it with more context than a basic map. If you ride buses, trains or a subway regularly, this is one of the more useful free tools you can put on your phone.
