I am currently working on an app and came across the following. Let's say we are making a table with whatever data (music as example) to use on a mobile device. What will the user like more swiping horizontal or vertical? To be more clear when you have your device in portrait what is more liked swiping from left to right (horizontal) or from up to the bottom (vertical)? What is in general more easy to do with your finger? I personally like the horizontal more, but this is maybe just an opinion.
I am not looking for an answer what is easier to code or how to code it. I am just interested in what is more liked among the users of mobile devices (maybe there has been a research on this, love to see it ;) ). And I am interested in what is better for your finger (maybe it does not matter or maybe it does).
