• Yes, the display is square and about 35mm diagonally (although the edges are masked off with a slightly rounded edge). I don't see the link you put to waveshare's module but it's a pretty standard 240x240 colour LCD screen that you'll see in a bunch of places.

    In terms of apps - it's a lot. Just checked and the average size of an app in the app loader is 2kB (although I'd expect that to grow!) - however there's 4MB of flash memory so you could theoretically install over 1000.
