Hey, that’s pretty good

Nice tool, simple and easy to use. Looks like a calculator but geekier, it’s great

Remove Ads Option?

The UI is clean and easy to use but the banner ads (which the screenshots deceptively leave out) are really annoying. There should be an option to remove the ads. I do not mind paying a small fee to do this and will happily use alternative apps that do not force ads through.

Great Dice Roller

Simple and easy to use.
Others have flash and animation but it makes it look amateur by comparison.
