Hey everyone... Over here!! I have a few questions to ask about apps.

Sorry about the un-discriptive title!

I'm designing a user interface for a travel app, and I wanted to chew your ear on what you like and don't on currents app interfaces.

Thing's like the layout, colour scheme, the flow from each page, what bugs you and what excites you?

Whistle blow on bad examples and the saints out there.
It doesn't need to be travel related!

I'm looking user interface, NOT the system behind it.

Thanks for reading and let's debate! Good app's are designed by you, the user!!
