Presets is a small tool that allow to set a number of configuration parameters with a single touch.
In example:

  • In the car: enable bluetooth, ringer volume to max
  • At the office: lower the ringer, disable bluetooth
  • At home: enable wi-fi, disable bluetooth, ringer up
  • At the theatre: lower the ringer to minimum, enable vibration

Select a name for your preset, define the parameters you want to change (volumes, bluetooth, wifi...) and save it. From now simply starting the app and selecting the preset, all the defined parameters will be applied at once.

It's all this simple.

The useful widget will show the last selected preset and allow to start the app with a touch.

You can get Presets from the Play Store free of charge.


Presets è una piccola utilità che permette di applicare una serie di parametri con un singolo tocco.
Ad esempio:

  • In auto: abilita il bluetooth, alza la suoneria al massimo
  • In ufficio: abbassa la suoneria, disabilita il bluetooth
  • A casa: abilita il wifi, disabilita il bluetooth, volumi medi
  • Al cinema: suoneria al minimo, vibrazione abilitata

Scegliete un nome per il vostro preset, definite i parametri che volete modificare (volume, bluetooth, wifi, ecc...) e salvatelo. Da ora avviando l'app e toccando il preset da voi creato verranno modificati tutti i parametri del dispositivo così come sono stati precedentemente definiti.

Più facile di così!

Il simpatico widget di Presets mostra l'ultimo preset selezionato e permette di avviare l'applicazione con un tocco.

Potete installare Presets dal Play Store gratuitamente e senza impegno.

Quick Dice Roller 2.1.0

The new version of Quick Dice Roller, the flexible, complete and handy dice roller, has just been released.

You can get the latest version of Quick Dice Roller on the Google Play store.

New features

As requested by many users, from Quick Dice Roller version 2.1.0 you can choose any image to use as icon for dice, dice bags and named values.
I suggest to use square images with transparent background (like png images), but you can choose any standard image. Here an example ready to be used by FATE / Fudge players:

You can also set any image as custom background. You can enable the custom background and select any image of your choice via app settings.
For best results try an image with low contrast, and remember to change theme (Light or Dark) if texts are not clearly readable.

You can enable the speech synthesis to get the last result to be read aloud. The voice and the language of the spech synthesis is the default for the system. Try to disable roll sounds to get a clearer speech.


Two new function where added to support the Aeon IV system (aeon) and the Rolemaster system (rolemaster).
The pool function was greatly improved by adding some optional parameters.
The online reference switched from a set of static page to a small wiki:

Other news

Google Code, the platform where I stored all the source code of Quick Dice Roller, is about to shut down.
I had no choice but to migrate to another service, so from now on you can find the updated Quick Dice Roller repository on GitHub.

Quick Dice Roller 2.0.0

It took a while, but finally the version 2.0.0 of Quick Dice Roller is out.
The change in the major release number is due to important features added to the dice rolling app.

Two new functions were added to support Shadowrun 4th and 5th edition.

Some functions (exp, expUp) were greatly improved, allowing optional parameters. Optional parameters can be omitted in order to keep formulas clear, or can be specified in order to make the function more flexible. Check the complete functions reference for further details.

The output of many functions were changed in order to make it more easy to understand, using same symbolism across different functions - i.e. the character "»" always refers to an extra roll, "!" stands for a success and "≡" refers to an alternate interpretation of the result.


Important changes were made to the overall aspect and interface. The main theme was changed to make it more clean.
Overall theme before and after
Edit panels were changed to dialogs in order to provide a better render on large devices.
Edit die, before and after
A special keyboard, customized for the needs of the dice rolling app, was added to ease the task of editing dice formulas. If you prefer the standard keyboard, you can disable the customized one via app settings.

Two new themes were introduced for a total of four themes to choose from: classic, clean, light and dark. It is possible to change theme from the app settings, and a restart it is no longer required.
Light theme, landscape mode

Named Values

Named Values represents a very effective improvement of Quick Dice Roller, bringing the app to a next level of flexibility.

The most direct application of Named Values is to use them as counters for game scores. You can use it to keep track of character's Hit Points, for example. But this is not the real purpose of Named Values.

Named Values can be used by dice by their label.
A Named Value whose label is "PTS" can be used in a dice formula such as "1d20+PTS". Each time the roll is made, the label is substituted with the actual value of corresponding Named Values. So if it's value is 10, the roll made is "1d20+10". If the value of this Named Value is changed to 15 and then the dice is rolled agani, the roll made is "1d20+15".

So, thanks to Named Values, you can define rolls that refers to a character's statistics and you don't need to change such formulas when the statistics change - just change corresponding Named Values.

If you play with a game using pool dice system, you can set a Named Value for the pool size (=number of dice to roll) with label "POOL", and one for the pool target (=value to reach to obtain a success) with the name "TRGT". Then defining a single dice with the formula "pool(1d10, POOL, TRGT)" you can perform any roll simply changing the value of the two Named Values.

And these are just two of the possible applications of named values. You can use them to define an overall modifier for the roll, or to computed derived values, or other.
I've defined a Named Value representing the current level of my character, and then i defined the following dice to automatically compute the damage of a Magic Missile (AD&D):

rak(1d4+1, min(rup(LVL/2),5))

that roll a single missile (1d4+1) at level 1 and another missile each two levels (round up current level divided by two), with a maximum of 5 missiles.

Open Source Project

From now on Quick Dice Roller become an open source project hosted on google.code platform. The project home is located at and contains all code and resources needed to build and run Quick Dice Roller.
I hope to intrigue some skilled developer so to get some help.


Without external help I can no longer mantain all the supported language except for English, Italian and French. And even the English translation should be fixed, because as you can read my english is all but perfect.
I hope that opening the source of the app will be of help from this point of view. The help of anyone is welcome.

Community and Beta Testing

A google+ community has been created to keep in touch with users about how to use the app, issues and suggestions.
All members of the community can join the beta test program in order to receive updates of the unofficial versions of the app.

Formula D / Formula Dé

Image (c) by EuroGames
A friend asked me to add support to Formula D / Formula Dé dice on Quick Dice Roller, but it turns out that QDR is already capable to handle the unusual dice used in this racing game.

First gear

First gear die is a four sided die labeled 1, 1, 2, 2.
It can be handled like a d2 so we can use the following expression:


Second gear

Is a regular cubic die labeled 2, 3, 3, 4, 4, 4.
This is a little tricky to handle, but not impossible. The expression used is:


That is:
Roll a d6 and divide by two (0.5, 1, 1.5, 2, 2.5, 3)
Round down (0, 1, 1, 2, 2, 3)
Take the lower value between the one obtained and 2 (0, 1, 1, 2, 2, 2)
Add two (2, 3, 3, 4, 4, 4)

Third gear

This is an eight sided die labeled 4, 5, 6, 6, 7, 7, 8, 8.
This is the Formula Dé's most complex die to reproduce. The formula used is:


We start with a d4 multiplied by 1.3 (1.3, 2.6, 3.9, 5.2)
Add 3.4 to this value (4.7, 6, 7.3, 8.6)
Round down (4, 6, 7, 8)
Take the larger value between the one just computed and 1d2+3 (4,5). This mean that if the computed value is 6, 7 o 8, it does not change. If the first outcome is 4, it can become 4 or 5.
So we have 1 chance out of 8 to obtain 4 or 5, and 1 chance out of  4 to obtain 6, 7 or 8, as required by the third gear die.

Fourth gear

Is a twelve sided die labeled from 7 to 12 twice. It can be achieved with this simple expression:


Fifth gear

Is a twentieth sided die labeled from 11 to 20 twice, that mean is equal to a d10 and can be achieved with the expression:


Sixth gear

This is a large thirtieth sided die labeled from 21 to 30 three times and like the Fifth gear die can be achieved with a simple d10:



Well, this is a simple d20 and no further explaination is needed...
