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.

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.

Chrono app

I’ve been using this app for about a month and it has really helped me be early and on time for my bus. The only thing I would say that isn’t that good is the fact that the bus always comes like 15 minutes later then the time the app indicates.

Les horaires

Les horaires ont besoin d'être mis a jour. Parce que quand je tappe sur mon arrêt ça dit que le bus passe vers 8h59(Terrebonne-Mascouche rue de vervier) quand que en réalité le bus passe vers 8h35 C'est une très bonne application, mais les horaires sont parfois très confus.

Trop long à démarrer

L’application affiche « downloading schedules » durant 25 secondes lorsqu’elle démarre. Pourtant, j’ai un iPhone 12, donc un téléphone assez rapide…
