***** "The other dice apps substitute wacky graphics for speed and utility. This does just what I want it to, and it does so smoothly and intuitively...The app is so logically laid out that you can start using it to its fullest potential within seconds of opening it up, and it displays detailed results of the rolls so that even the most obnoxious of rules lawyers has the evidence of fair play."
***** "You know what's awesome? An app developer who actually pays attention to his user's concerns, and then makes changes based on their suggestions. That's what this developer does. Keep up the good work."

Brilliant app

Let me add voice to the chorus of praise for this app. Truly an outstanding, easy to use, useful app. Although I still pull out the physical dice for monumental rolls I use this app for just about every roll. Designed by people who love gaming.

My single teeny tiny nit would be to show the results with the most recent rolls (d6 = 4, 4d10 = 19, etc). It's not a complaint just a request to make it that much better.


OMG yes. Why havn't I always had this? Perfect for anyone who wants to speed up combat, especially at higher levels when a fistfull of dice is the norm. Also great for those DMs and players who prefer to play inebriated (i.e. nearly everyone). My only critique is that the aesthetics are a bit spartan, they could use some sprucing up with fantasy elements such as fancier scripts and textures.

Love it

I love this app, I use it every gaming session. It has great features and it shows you what the base role is, which is important for things like critical hits etc. It is fast, much better than carrying my die bag around and can make any type of role. Can also include any modifiers. If you game, buy this app, you won't be sorry.
