Chrono Mobile is the official application of the public transit companies (exo, RTL, STL, STM and REM). 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.
