Getting off a Flixbus

In my experience with Flixbus (in Germany), the driver announced each upcoming stop around five minutes before it was reached. With passengers embarking / disembarking and loading / unloading luggage, the bus usually stayed at a stop for at least 5-10 minutes.

So you don't need to be looking at the app constantly, but it is still a good idea to be generally aware of when the bus will reach your stop and be alert around then. In particular, it would be helpful to at least keep in mind when the next stop is yours.

I believe that the bus always stops at every stop (i.e., does not skip stops if no one signals that they intend to embark / disembark), and this was always the case in my trips, but I am not sure if this is generally true. Flixbus allows tickets to be purchased on the spot in the bus, so I think it is highly likely that this is indeed the case.
