Chrono gives you all the information you need to get around on public transit (bus, metro or commuter train) in Greater Montréal, Quebec.

It allows you to consult all bus, metro and commuter train schedules in Greater Montréal, even offline. That means you can access the app regardless of where you are in the network!

Chrono is customizable. You can select your usual bus stops or train stations, receive alerts about service disruptions* and see the next arrival times at your favourite stops at a glance as soon as you open the app. Chrono even displays the next arrival time of your bus or train in real time*.

And that’s not all! If you don’t know what your public transit options are where you are, or if you’re lost, you can use the interactive map** to get your bearings and see all the bus stops, metro stations and train stations nearby. Based on a point you choose on the map or an address you enter, Chrono will calculate the best and simplest itinerary to get where you want to go.

If there is a service disruption, Chrono gives you the option of planning a new itinerary so you can be sure to choose the best public transit option. Chrono was developed in partnership with all public transit operators in the area, and it collects information at the source, which makes it the most comprehensive and reliable public transit app.

Great app

Now I know when my bus arrives or when my train is boarding. Great app. Would recommend to all commuters. And it also lets me save my schedules. How great!

Utile mais bug depuis dernière mise à jour

Depuis la dernière mise à jour, aucun horaire n’apparaît.


C’est suite au téléchargement d’une nouvelle base de données que le problème est apparu. Le seul moyen de réparer l’erreur a été de désinstaller et réinstaller l’application. J’ai alors perdu tous mes favoris.

Très utile! Mais gros problème.

J’ai remarqué que lorsque j’utilise l’appli, la batterie de mon téléphone baisse à une vitesse alarmante. 1% à chaque 30 secondes minimum. Aussitôt que j’éteint l’appli, tout est normale.
