True Random Number Service
Advisory: We only operate services from the RANDOM.ORG domain. Other sites that claim to be operated by us are impostors. If in doubt, contact us.
Official iPhone and Android App
Our official app brings the six most popular RANDOM.ORG randomizers directly on to your iPhone or Android smartphone. We spent a lot of time getting it just right, so to cover the costs, we have decided to make some of the randomizers paid, i.e., you need to unlock each for a small fee – or unlock them all at once and get a solid discount. Once a randomizer is unlocked, you can use it as much as you like.
Coin Flipper
The Coin Flipper contains a total of 100 coins from all over the world, which have been donated by RANDOM.ORG fans over the years. To flip a coin, simply tap the randomize button. To see the full coin selection, tap the little settings cog in the top left corner of the screen. Our favourite coins are the Ancient Roman ones and the US Challenge Coins. The history area shows your past coin flips.
FREE Coin Flipper is unlocked when you download the app. You can use it as much as you like at no cost.
