I use my iPad for running and playing my games, and while dnd beyond is thorough, it's information layout is just terrible. You can really tell that it was made for phones not tablets. And it's kinda lame that it doesn't pre-load its content, so you're waiting for a slow network while trying to access information that you told it already that you want (when you made your character).
I found Fight Club 5 on the app store, and it's a lot better in both layout and speed, but it also has a pretty high learning curve for someone that's new (you need to use XSLT to make your compendium due to copyright issues). It also won't automatically use the system dark/light mode theme - why do apps not support this? What year is it?
I'm still looking for my perfect app. I wish wizards would make one that's more native for tablets.
