It is one of the more useful apps of its kind, with a simple design that is easy to use effectively. I tried a few other similar apps, but this one is my preferred and go to. I only have two suggestions to improve the app: make the dice roller include dice with different faces (this can be accomplished with a custom list, but it would be better to have it conveniently organized in the dice section) and provide some reorganization capability in the custom lists for users.

I love Randomizer for art inspiration, building lists for themes, moods, characters and more! I also use it for randomizing games with modular elements (namely Marvel Champions). I would like to be able to better organize my lists, though. Right now, lists are only displayed in order created, with no option to change their position. I'd like to see the ability to reorder my lists into unique folders/nested trees for easier use (and as a bonus, picking multiple lists would require fewer taps).

This app is unreal. Super, super useful and feels like it's made by someone who actually cares about making something usable for people. I REALLY love the fact that if you have custom lists that you can import and export them. I can't believe how hard it is to find an application that can do that. What I would love, though, is when you do an import to optionally either import and remove any lists not in the backup, or to do a deep merge with the lists already saved in the app.
