Great app! Only complaint is that if the screen goes into landscape mode, it clears everything, but that's not a super big deal. edit to add: There doesn't seem to be a way to delete lists, which is inconvenient if you only need a list temporarily. Additionally, renaming lists creates a duplicate list instead of overwriting the existing list

This is a pretty good app! The coin choices especially are amazing. The only thing missing, and yet the most important feature imo, is being able to choose from a list. Currently, the list randomizer only shuffles items in a list, but you can't use it to choose between options in a created list. Also if it could keep track of results, that would be great. And final suggestion, the menu wheel is cool, but a dropdown menu would probably be better.

There is an infuriating bug in this app. It does not respect my phone's auto-rotate setting! Even when I have auto-rotate disabled in my phone settings, even the slightest tilt or turn of my phone will cause the app to switch to a horizontal view, resulting in all the generated numbers on the screen being deleted. This is extremely frustrating. And the latest version continues to repeatedly crash, especially when the network connection is weak. Hopeless.

I mostly use the coin flipper and haven't explored the other features, and tend to use the website primarily. That said, the flipper works well and is generally reliable. It has room for improvement in the image quality of the pictures of each coin. Try the app for yourself, it's worth the time.

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

A really good app that does just what I was looking for, generates numbers, and so in a variety of fields. Furthermore, in the 'lottery'-segment - which is what I primarily was looking for - m the No's are preformatted for the game of your choice, in a lot of different countries. Clean, neat, jwit (just what it takes) A BIG plus: no f-ing ads! hence, should I win, they will receive a part.

Does what it needs to do with no intrusive ads popping up in your face. Would appreciate some small features like with the integer selector if we could select an amount of integers to generate (7 at once for example) and to generate a new list of integers whilst keeping the previous list. But regardless, it's still fast and works well. Takes up a small amount of space and doesn't have any annoying notifications. If you're looking for a random generator of some sort this app is all you need.

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.
