Dice Champ

With this app you can configure your most used dice rolls, be it weapons, spells, to hit rolls, saving throws, etc.

And you can create conditional rolls and modifiers you can easily apply at roll time, such as critical hits or your paladins smites.

You can even designate some rolls to be applied after, if you choose, Bardic Inspiration, for instance.

You can create categories and creatures for easy filtering.

Your logs are rolled, in case you want to go back and see what happened when.
