About this app

All randomness wasn't created equal. This official RANDOM.ORG app offers certified true randomness, generated with atmospheric noise and independently approved by several testing labs. (See sample certificate in the screenshots.)

- Coin Flipper with 100 different coins from Ancient Rome to 27 modern currencies
- Dice Roller to roll up to six regular dice in one go
- Card Shuffler to shuffle playing cards and draw them one at a time
- Lotto Quick Pick with more than 170 lotteries from all around the world
- Integer Generator to generate true random numbers in configurable intervals
- List Randomizer to create and randomize your own lists of items

Note: This is not a gambling app. The app does not simulate any games, it simply allows you to roll dice, shuffle cards, etc -- using certified true randomness.

All randomizers are free to use and the app contains no advertising. If you like it, you can buy us coffee from the Settings screen -- much appreciated :-)

RANDOM.ORG was founded in 1998 and generates certified true randomness from atmospheric noise, which for many purposes is better than the pseudo-random numbers typically used in computer programs. Our mission is the generate the highest quality true randomness and make it available to the world in useful forms.

So sad! Been using this app for such a long time.. Maybe over a year. I kept a list of a few collections, along with some info about each item. I wanted to delete one of the lists, so I selected the settings button while in that list, and selected clear data. I didn't know it would erase all my lists 😭 I had almost 150 on one. Awesome app, worked perfectly but don't make the same mistake I did! Unfortunately it took so much time I probably won't make it again

I used to like the app, but I don't like the new sleeker looking (but far worse) update. A lot of features are gone now and some of the features either don't work or are totally unintuitive. As an example of a now missing feature liked being able to pick 3 numbers between 1 and 100 for example. Now it's just 1. For broken or unintuitive, when I tried to make a list to randomize, I don't see how to make more than one word. I'll probably try to find a different app and uninstall.

it's not pretty, but who cares? it's perfect for when you can't literally flip a coin/roll a die, has zero ads, and it seems much more stable since the Dec 2019 update. the list randomizer is a little clunky, but i love being able to save multiple lists to randomize whenever i want (very useful for choosing a restaurant). edit May 2021: removed one star because as great as it is to get fresh random strings every time, i really wish i could use it offline.
