When the Transit app launched in Montreal in 2012, its developers aimed to create a unique tool for everyday commuters, and in doing so, they found a focus solving a more minor, more human problem — a moment of uncertainty that hits every rider waiting at a stop. 

"When is my bus going to come?" 

Other navigation tools forced users to plan an entire trip before answering, according to Stephen Miller, policy lead at Transit, but Transit flipped the script. It was built for real people — riders who already know their routes, their stops, and their city, but want to know "where the closest stop is located and when the next trip will arrive." 

More than a decade later, that minimalist idea has grown into one of the most widely used public transportation tools in North America. Transit is used by over 20% of all transit riders in the U.S. and Canada every month, putting the app in a league of its own among independent mobility apps. However, the company's mission has stayed remarkably consistent. 

"For many, many people, it means a lot to have a tool, a companion, that helps them take transit and get around by bike or on foot," Miller says. "That's really what animates our mission, which is to make life better without a car.” 

Built for the World We Actually Live In 

In a "perfect" city, riders wouldn't need an app at all. Trains would arrive every five minutes, buses would never detour, and the streets would be safe for anyone on two wheels. But, as Miller points out, "We don't live in that world." 

Instead, we live in one where delays, funding shortages, and unpredictable service are routine. Transit's role is to bridge that gap by keeping riders informed, calm, and connected even when systems aren't running perfectly. 

Research supports the impact of these tools, as Miller explains, riders who receive accurate, real-time information perceive their wait times as shorter and are more likely to keep riding.  

"It's important to communicate when things aren't perfect, so people can adjust," Miller says. "Mastering those basics requires a team effort, not just within a transit agency, but also with public- and private-sector partners, and we help transit agencies do that work every day." 

Although Transit's success is in telling people when their bus is coming, it's also in listening. Most of the time, people need more than just accurate transit service updates. Through constant app engagement and user feedback loops, the platform has become a direct line between riders and the agencies that serve them. Transit makes it a point to ask its users about their trip, including details like whether a bus shelter needs repair or if the bus arrived at the time indicated by the app’s real-time countdown. 

"Because people are opening Transit multiple times each day, right at the moment when they are thinking about how they get around, our app is a great touchpoint not just to guide riders through a trip, but also to listen to what they have to say about what's going right and wrong on that trip, and to inform people about efforts to improve their commute," Miller explains. 

This idea is where Miller says apps in general, and Transit in particular, can help shape habits. It encourages people to forgo a car-centric society and ride public transit while helping shape the future of their own city through an established two-way feedback loop. 

Sustaining Growth Without Sacrificing Trust 

In an era where nearly every navigation app profits from advertising, Transit stands apart and doesn't sell or share personal location data with advertisers.  

"The dominant monetization approach for navigation apps, from Google all the way to the smallest players, has traditionally been advertising," Miller says. "That means collecting massive amounts of data about users, and very often, installing software kits into your app that sell this information to data brokers who build out individual advertising profiles." 

Transit has built a sustainable model that blends user subscriptions with partnerships from transit agencies like Maryland Department of Transportation Maryland Transit Administration and Metro Transit in Minneapolis-St.Paul. It may not be a simple path, but it aligns with the company's values. 

However, Transit does share limited app usage data with transit agencies as part of their partnership to help them understand their riders and improve their service. 

"We've done it in a way that we can look at our users, our partners, and ourselves in the eye, because our business doesn't survive at the expense of our users' privacy," Miller says. 

The New Language of Mobility 

The company's recently launched Transit 6.0 redesign is its most ambitious to date. Miller stresses that, for riders, apps — no matter how pretty — need to be easy to scan and understand. 

With this in mind, the new interface centers on bold, horizontally scrollable ETA cards that display real-time arrivals, crowding levels, and service alerts in large, easy-to-read numbers. 

"The goal is to provide the most critical information in a quick, clear, easy-to-browse format," Miller says. 

The overhaul also introduced a custom typeface, Puffin Transit, designed in collaboration with Pieter van Rosmalen and the team at type studio Bold Monday. The font is round, approachable, and highly legible on small screens, which is perfect for an app that wants to feel friendly rather than technical. 

Even the color system has been reengineered to handle dark mode more intelligently. "About half of people use Transit in dark mode, even during the day," Miller says. "At night, it jumps up to about three-quarters."  

Color is crucial to the public transit experience because it distinguishes different lines, systems, and emergency alerts. 

"Since our app works across so many cities, with so many different hues and tints, we had to develop a way to handle these adjustments programmatically," Miller says. "So, we developed an algorithm to match each color to ensure that it remained useful for navigation, while also being legible on dark backgrounds." 

The result is a subtle yet significant change that provides a calmer interface, reinforcing Transit's goal of being both functional and intuitive. Plus, accessibility has become a defining feature of the new design. 

Roughly one in four Transit users has some form of accessibility need, spanning from low vision to mobility limitations.  

"We regularly get feedback from users about accessibility issues, and it's a big focus for our team," Miller says. "And before release, we specifically included users who had offered useful feedback in the past in our beta testers group." 

Transit 6.0 improves support for dynamic text, screen readers like VoiceOver and TalkBack, and offers customizable walking and biking speeds. The app also flags step-free routes and accessible transit trips. 

"When it came time to work on Transit 6.0, accessibility feedback from users helped inform our decision-making, and we made significant improvements to how the app handles dynamic type size for low-vision users," Miller explains. 

Working With Agencies, Not Against Them 

Transit knew from the start that it was not a "disruptor" tech company. 

"Our mission is to make life better without a car, and we can't achieve that mission by working alone," Miller says. "It means we also have to work with, and be valuable to, the public servants who run the transit networks and manage the streets. 

For agencies, Transit offers a ready-made platform to communicate detours, collect feedback, and reach residents who might never attend a town hall. Doing this work in a partnership has allowed for a much bigger impact than if Transit tried to do it alone. 

"[Other apps] think that they alone can revolutionize transportation. That's not who we are," Miller says. "We believe in our bones that life should be better without a car, we respect our users and put their needs first, and we do it all in deep partnership." 

More than a decade after it began with a straightforward question, Transit is helping cities answer a bigger one: What does a world built around people, not cars, actually look like?
