Invest into features we actually need

Transit app, Google maps, Apple maps and tons of other apps already provide transit data, and in fact do a much better job.
Communauto also already has its own app.

Stop trying to mimic or compete with these apps. Invest into something that is actually useful, like reloading opus card after i scan read it???

Works better than Google/Apple Maps

Has up to date rerouting info missing from the map apps. Life saver.

Broken server

OPUS card reading? Not really working, it starts the nfc read but doesnt go further and doesnt display anything

Chrono server is always down, cant create an account

Each time you close the app it tries to download the schedule and it takes an eternity on a 400Mb internet, that server also needs an upgrade…

This app looks like it was made by an amateur, not up to the level it should be released
