*************** Descriptions of the Free Features ***************

Heres a brief description of Natural 20 Lite’s screens, which are available free!

~ Quick Roll
Simply pick your dice, and you have an instant result. Ideal for Dungeons & Dragons, Quick Roll offers the following eight dice; D2, D4, D6, D8, D10, D12, D20 and D100.

~ Multiple Dice
In multiple dice mode you can mix your dice together as you please. Tap each row to add five at a time, or use the plus or minus to add or remove one. You can roll or remove individual dice again. Stats, such as average and the sum, are displayed for each roll saving you counting on screen.

~ Teachers Die
Handy for the classroom, this die will be helpful for Maths and English. You can use it to randomly pick letters, numbers and mathematical operators.

~ Roll History
Natural 20 keeps track of all your rolls, so you can prove you actually rolled that 20! The dice stored in your history can be easily re-rolled and filtered. You can move the dice around the screen, and it will remember your order.

~ Distribution
Distribution allows you to create probability distribution plots for specified dice. These will show you the percentage chance of rolling a particular face value, and you can compare actual rolls against theoretical results. However, large numbers of dice can take a long time to calculate for theoretical plots.


*************** Features unlocked with an in-App Purchase ***************
For $0.99 USD you can permanently unlock the following screens, with a single in-app purchase.

~ Calculator
Great for large numbers of dice, or combinations with a modifier.

~ Custom Die
Custom Die lets you choose the sides of the dice, by separating them with commas. Natural 20 will pick a single item, or order them randomly into a list.

~ Colour Die
This will give you a random colour, just run your finger across the screen like a paintbrush. Displayed on the screen will be some basic information. For example the colour’s hex number, HSB and RGB values.

~ Direction Die
This will point you in a totally random direction with each spin. Swipe the screen to spin it, however you can only influence which way it spins, not the outcome!

~ Success Die
Repeatedly rolls D6’s, discarding when they fail to meet a certain value. The total successes are displayed.

~ Word Die
Keep collections of words, to randomise at a touch. Ideal for selecting locations and enemies randomly. You can even randomise your words as a whole list.

~ My Dice
My Dice allows you to save your own collections of dice, along with a description and optional modifier. These can be easily searched through, and rolled from a single tap.

~ Dice Builder
Chose how many sides your dice have, and their colours!


*************** Random Number Generation ***************

Natural 20 Lite uses your devices built in randomiser (arc4random_uniform) to generate values. This has been tested with large numbers of dice, to ensure there is no bias present. In the full version, Natural 20 offers a screen called "Distribution". This allows you to test this yourself, with rolls of 100,000 dice at a time.

Pros and cons of Natural 20 Lite App app for iPhone and iPad

Natural 20 Lite App app good for

The best dice app I found to date. All the Features I need. Will buy the pro version as soon as i can. The only thing that could be better is the interface. Didnt found the roll button the first time. other than that excellent tool.
Everything genius is simple. As this app. My DnD parties arent going without this app and i am horrified, why isnt it at the top of dice list, as it should be.

Some bad moments

Simple dice roller with all the basic dice and a clean looking interface.
Not a perfect UI but certainly useable. Enough options. Its simplicity will keep me using it.
My friends and I love this app. It works great and beats the hassle of looking for the right die and then struggling to read the tiny numbers with our old eyes. Not to mention you never have to worry about the dice rolling off the table!
Very good for dice-based games, for instance, D&D. But the dice are so rigged and you get low numbers 60% of the time, its bad for roll checks so just try and stick with normal die for that
This app is great. Its got all the dice you would need for any game, including d100, witch I havent been able to find for sale anywhere. Loads fast to. All around great app.( could you tell Im a nerd?)
