About this app

CritDice is a quick and easy dice roller. CritDice can be used to roll dice for D&D and many other games. Here’s a short list of what CritDice can do for you…

•Simple dice calculator supports many dice types, combinations of dice, and modifiers.
•Dice rolls are totaled and shown in a large popup, along with detailed results of the individual dice rolled.
•Roll dice by tapping the ROLL button. The result will be instantly displayed - no waiting for 3D dice to finish animating.
•Dice formulas can be saved as "favorites", allowing 1-tap rolling.
•Access a list of all previous dice results, and tap any result to re-roll.
•Customize dice sounds. For example, a custom sound can be played when a 20 (critical hit) is rolled on a d20.
•Optional text-to-speech announcement of dice roll results.
•Intuitive minimalistic user interface based on Google Material Design guidelines.

CritDice provides a dice bag with support for modifiers and the following dice types:
•dN (custom dice, N = any number)
•dF (Fate/Fudge)

Dice are input using standard notation and the results are completely random. A dice roller should be able to handle any combination of dice, and CritDice provides this capability. Here are just a few dice roll examples that can be performed using CritDice:

The paid version of CritDice features an advanced dice bag supporting additional roll types:
•Custom dice (any number of sides can be specified)
•Fate/Fudge dice
•Keep highest or lowest
•Drop highest or lowest
•Automatically re-roll specified values, any number of times or only once per die.
•Exploding, compounding, and penetrating dice
•Count total successes and optionally subtract failures

After rolling dice the results will be instantly displayed in a large popup, enabling you and your fellow gamers to easily see the results. The results can also be spoken by your device.

Special sound effects can be configured for certain dice roll results, such as when a critical hit (20) is rolled on a d20. Dozens of sound effects are included to choose from. You can also configure dice to use any additional sound effects you've downloaded.

Dice inputs can be saved as "favorites" and rolled with a single tap. Favorites can have any name and can be grouped by category - useful for when you are playing several characters or want to keep things organized.

A list of previous dice roll results is also provided, with the most recent result at the top of the list. Tapping an item in the list will cause it to be rolled again. Previous dice rolls can be converted into favorites with a tap of a button.

CritDice is compatible with the dice systems used in D&D and many other games. Some of the compatible games are listed below:
•7th Sea
•13th Age
•All Flesh Must Be Eaten
•Anime: Beyond Fantasy
•Black Crusade
•Call of Cthulhu
•D&D and AD&D (all editions)
•Dark Heresy
•Iron Kingdoms
•Mutants & Masterminds
•Only War
•Rifts (Palladium Games)

Excellent app, not obnoxious or convoluted. Unfortunately there's no feature to roll multiple sets together, or at least I didn't find it. It just adds everything together, which means rolling an attack all at once is pretty useless. If you could type "2d20K+5, 2d6+7" for an advantage attack with a greatsword, and be presented with 2 results at the same time upgrading would be more worth it. Add that, and I'll upgrade and increase my rating, but it's still a good number generator.

Overall the app is extremely nice to use, when you have to roll large amounts of dice. Although when making large numbers of equations for differing amounts of hits it's very annoying to have to get rid and write a whole new one. Maybe allow a way to tap the screen and allow you to delete at the place tapped. If it weren't for that 5 stars, but without that feature 4 stars.

I've used a lot of dice rollers on Android. Most of them simulate the dice rolling in 3D on the screen, which can look cool, but for some stupid reason they won't calculate the results of the roll until the dice stop moving. This can be obnoxious when you roll a lot of dice at once. I've found CritDice calculates results instantaneously, which I'd much rather have than the novelty of some virtual dice. The layout is simple and clean, and organizing favorites is really easy and helpful. There are tons of advanced things you can add to your die rolls to ensure you get exactly the output you want. Just a really practical and functional dice roller. Love it.
