About this app

Chrono Mobile is the official application of the transit corporations (exo, REM, RTL, STL and STM). It has been developed to give its users a complete metropolitan experience.

Whether by bike (BIXI), metro, Communauto, river shuttle, bus or train, Chrono lets you buy your fares, find the best route for your next trip or reserve an alternative mode of transportation.

Download the application, create, and personalize your account to benefit from all the features:
-Avoid queues, reload your OPUS card, and buy fares.
-Access information on the entire metropolitan network: real-time* and planned complete schedules, bus and train positions and occupancy levels, network map, etc.
-Reserve your next BIXI, book a Communauto or Communauto Flex
-Plan all your future trips by public transit or bicycle.
-Create favorites and alerts for lines and stops you use often.
-Read the contents of all your cards (OPUS and occasional) and find a new point of sale to buy your tickets.

* When data is available.

Just as other reviews have stated, the app reads the cards, allows you to purchase a fare, but then can't find the same card to load the fare. Tried this with three different cards, two different phones, and finally one loaded after taking off the phone case and about 10 minutes of moving the card around. I'll note that taking off the phone case is not required to read the cards. I have used the Opus En Ligne reader for years and it works great. I just used it to load all three cards in minutes.

Bonjour Louis, il faut réutiliser la même carte OPUS pour la recharge et la lecture. Après le paiement, vous pourriez recharger votre carte sur un autre appareil. Après 30min, les titres non-encodés, seront annulés et remboursés. Merci pour votre commentaire, cependant Opus en ligne est une technologie en fin de vie et votre sécurité nous importe !

This app is mainly only useful to recharge your Montreal transit pass. If you want to know the times of when your buses are coming or plan a route, it doesn't do that very well and it has a terrible layout and functionality for those things. But you can recharge your transit pass, so for that I use it and for everything else I use different apps.

Although it saves us from doing a trip to recharge, it seems to be done by children. it gets you to step 3 (card charged but...) and gets confused. Asks you to tap the card to finalise, but won't read it and you don't know if your card is charged or not. If you press help, it imposes on you cookies. something i am very opposed to. so sometimes i take my chance, but usually charge at STM points. Paradoxal, but easier than using the app.

Nous sommes désolés. Recharge OPUS fonctionne bien avec la majorité des téléphones, mais il peut arriver que ce soit plus difficile. Au cours de l'année 2026, vous pourrez acheter des titres virtuels qui résideront sur votre téléphone sans avoir besoin d'une carte OPUS.

What’s new
