User reviews

no offline... what's the point?

I downloaded this to be able to access the features of random.org offline. Turns out the app doesnt work offline, it just fetches data directly from random.org... so why wouldn't I just go to random.org if I have service... pretty pointless for my use case.

Why I like Random.org

Besides the obvious (giving a lot of types of randomness,) they teach us a lot about randomness. You can also create your own random choices (e.g., days of the week, people on a list, colors, etc..) I haven’t found better, but I’m also not looking.

Just all around solid.

This is by far the best randomizer on the app store. It’s free, with no ads, and most importantly, doesn’t collect data. I would like to see the option for no repeats, an option to favorite a randomizer so you don’t have to spin the wheel to get to the integer generator every time ya’ open the app, and maybe the ability to add bias, but it’s still amazing. 7 stars if I could, so 5 stars.

Wish for…

Could use an offline feature. Also wish it was easier to alphabetize or reorganize the list.

Huge fan

Random org provides true RNG not seeded from time stamps. Love the app/website, they always maintain free service. I have used random org for over a decade. I would pay for this
