Ratings and reviews

At loss of words to express how dismal it is. Getting a full day schedule for a particular line and station is impossible and/or incredibly onerous. Unless you fit one of their standard travelers' profiles, this app is USELESS. Interestingly, the response to my post was in French, asking for more details... Anyhow, I needed to download the FULL DAILY schedule at a given station. Pretty much impossible in the app... RER B, Luxembourg. I just realized that it's hidden under "Departures at"...

Got a navigo 1 day ticket. Tried to buy another the next day and was not able. Any attempt to buy a new pass fails with a message that the payment request was not successful. There is no option to select a new payment method. Tried signing out, reinstalling, clearing cache and data, nothing worked. Will be resorting to a physical card for the remainder of my stay.

Works fairly well. Be sure to have NFC turned on and a data connection before opening the ticket screen or it may freeze for a few seconds (requiring you to step aside to let others pass). Reasonable route-finding tools (I just used Google maps instead tho). But super convenient to have your tickets on your phone, to see your balance, and to add new ones without going to a ticket machine. And worked at every turnstile I've tried except one, including on the RER. Odd no one seems to use it.
