Is there a comparison of Web and mobile versions?

Newbie here – I promise I did look for an FAQ or pinned topic before posting this! I just created a free TPE Web account, and I would like to upgrade that or buy the iPadOS app (or both!), but I haven’t found a webpage or Forum topic that discusses the similarities and differences between TPE on different platforms. My laptop screen isn’t that much larger than my iPad, so “more resolution” is probably only part of the difference; can someone point me to such a discussion, or reply here? Thanks!
