Cool app. I use it everyday. I just wish the name of the streets would be clearer and easier to read, especially on the night vison. ( bigger font and in white not grey ). The cursor should also be a different color. A bleu cursor on a bleu track makes it harder to follow. A good feature to add would be to synchronize the screen with the cursor just like Wase or Google map so we won't have to manually zoom in or zoom out and swip left and right.

Live GPS tracking almost never works, UI bugs, poor design. The 'self' GPS dot is visible only half the time. Waste of screen estate [especially for next arrivals - very annoying when you have 20 favs]. No favorite grouping like competitor apps [promised in 2018!...] Favorites order is randomly destroyed. Can't search for a bus line without knowing the parent company. Some bus schedules are missing entirely, even though the respective lines have been active for months.

Only had basic features other apps contain. Lacks bus gps location on map, no auto populating stops when GPS is active, and no way to categorize favorites, making it very difficult to navigate through going-returns location. UI is the cleanest out of all other apps which is one thing I do appreciate. Also downloads maps without permission over data plan when wifi is unavailable. Will try again if they ever implement the missing features.

Hello Kevin, All the bus are not equiped with GPS so GPS location on map cannot always be displayed. Favorite categorization will be soon available. Feel free to contact us at for any comment, your feedback is very important to us to constantly improve the app. Thank you.
