Music Practice Routine
In my daily, music practice, routine I play one or two sets chosen from 23 sets of melodic sequences. (There are seven sequences per set, and each sequence I play around the circle of fifths.) I could practice them in order but it’s better to decide which set to play next by randomly picking it. So I use the list randomizer on this app. Randomly picking the set makes sure I won’t, over the months, neglect the latter and more difficult sets of sequences on my list; that neglect builds up over the occasions where I neglect my daily routine for many days, forget where I left off, then just start at the beginning again. Randomly picking the order each day offers me the best assurance that my practice of these exercises will be evenly distributed in the long run. It also gives me a little boost of excitement as compared with taking things in a predetermined order. If you’re a music student who has recently learned all your major and minor scales, and if you don’t have time each day to go through all of them, it’s probably better to randomly pick a smaller set of scales to practice. The “list randomizer” in this app is perfect for that: just enter the names of each scale on a list (the list will be saved), hit the big “randomize” button, then practice as many of the scales you want in the order shown. The next day you’ll (most probably) have a different order, and in the long run your practice of these exercises will be evenly distributed.

use it very often...
...but I really only need the Integer Generator for what I do, so it would be nice to have just this instead of having to always “twirl the wheel” to get to it each time I open the app. Also, I agree with the person who said that it is a bit unreliable in the latest OS of 13. Otherwise, it’s a joy to have and it has replaced something I had been using previously for over 10 years.

Needs history for random list results
Please add this feature. Great app otherwise. *ORIGINAL REVIEW* Purchased this app not knowing how it would function since there is no trial, found out that there is no way to keep track of generated random lists like the coin toss. Also, there is no “shake” to randomize feature. Was trying to use this app to generate a set of 24 draws on an ESP app using the random list (Green/Yellow/Red/Blue) using the first (1.) result as the draw color, however, since there is no history, its very tedious and time consuming.

Good, but missing options
The interface is good and it’s what you would expect; the results feel truly random and should fit your needs. My main frustration is that there isn’t an option to flip multiple coins, or draw multiple cards other than one at a time. A slight annoyance but Indefinitely would not have purchased the app if I knew this beforehand, as now I’m forced to open the browser version regardless. It’s a good app, just know that you don’t have that option.

Please make it work for the apple watch too! It would be really cool! I've been waiting for this app for so long and they finally did it! Great job! Real randomizer that uses some sort of wind speed measurements to find out a random number so it's more trustworthy than most of other random number generators that work because some simple algorithms! Deff to have you you ever used their website!

Very good randomizer
This app is well put together and more convenient than using a web browser. I also like being able to save lists and use them over and over without having to reenters them each time. I recommend this service (either the website or the app) to anyone who has any need to work with randomness.

Fantastic and useful
If I was William Morris, I would have this app in my home (look it up). This is a beautiful app, easy to use, all the right options, and flawlessly constructed. It's also wonderfully useful- I use it for gaming, the occasional lottery ticket, and settling choices when I want some real world randomness to be harnessed. I use it often and love it.

Almost awesome!
I have been waiting for this app for years, and it's finally here! I have no complaints about the app as is, and it's a great start. The things that would bump it from great to perfect for me would be an iPad version and more functionality. I use the integer sets and sequence functions on the web quite often, and it would be nice to see a mobile version of those.

Best app for tabletop gamers!
I love rolling dice but sometimes you just want instant (and quiet) results. This app gives you reliable randomness - the best! Only thing I ask is for the ability to have colored dice and roll dice of multiple sizes on the same screen. Still, this app rocks!

Pay wall
I’m a very indecisive person when it comes to things that won’t affect me in the long run. When I saw there would be an app for an rng generator I thought oh that’s neat I’ll just use that. Well everything accept the coin toss is Locked behind a pay wall. If you haven’t noticed most choices you make have more than two options. I don’t want to pay three dollars for something you can do online. Don’t get the app if you don’t want to spend money. Case closed.

Bug in List Randomizer
The app isn't the prettiest, but it works—mostly. There's an annoying bug that leads the last character in list items to disappear while editing the list. To fix it, you basically have to re-enter the final character on whichever item(s) are missing them and quickly exit the list. Even then, it's not foolproof.

Good randomness but needs an update
The randomness here is very good. I only wish they had support for multiple types of dice, especially that one must pay to use that feature. An update to support retina would be great too!

Great but missing some features
Just about the only option out there for true randomness, and that's no small thing. The app still needs a sequence generator and multiple number generators to be as complete and useful as the website. Still, very much worth it!

Truly Random
I love this app and the whole premise behind it—it generates truly random results (you can read about it on their website).

why is everything so tiny?
All the results are very tiny. You can shuffle a random deck of cards, but good luck seeing the actual cards. Same goes for all the tax results and so forth. There should at the very minimum be a zoom option in the preferences here.

I use the website integer generator a lot. I bought this version $3. The numbers pile up on each other so it's messy and not really readable or usable. Back to the website. I'd give it one star but parts of it are ok.

Flip a coin to determine it’s worth it
I really love the app in that I can use it for dice rolls or determine if I want fish tacos or steak quesadillas but I just discovered the app only works when you have service. I would offer five star but the online-only coin flipper reduces to three, especially since I paid for the extra coins.

Not as great as the website
I was needing this app because of a feature on the website. I purchased the random integer feature and was disappointed that I couldn't get random ranges for integers like the website. If this could be added, I'd totally reverse my rating and the app would be useful.

Not generating fast enough
Love the app never had a problem like this before but the generator isn’t generating consistently or fast enough it’s taking almost 1 to five minutes or not generating at all now if you could fix this as soon as possible that would be great

Noticeably slower
Has slowed down in the past couple months when, for example, picking a random number from a range. No idea why. Also, can we PLEASE get it to remember the last picker chosen?

Would love to see customizable, personalized default settings. I use the same set of parameters, for the same function 99% of the time I’m using the app. Stinks that I can’t start there every time.

On the edge of usefulness
One of the major features of the website is generating integer sets, but this app allows you to only generate integers one at a time... For $0.99. I'd give a higher rating if the app were as functional as the site. Until then, only 2 stars.

Good, but....
Why pay for the randomized when you can just use the browser on your phone? It seems a little weird. Also all I really wanted was a number randomizer and the spinning thing is confusing.

Good start. Keep going
A few things would make this 5star. 1) custom decks from lists. Make a list and treat it like a deck, taking out list items that have already been picked 2) different dice 3) gaming tables (such as pathfinder or dungeons and dragons) that can hold detailed info 4) shareable tables from point three Interface is nice. Keep going please!

If you like a coin flipper, this is great. But every single other mode is going to cost you either $0.99 or $2.99 for all of the randomizers. Just use their website if you need a random number generator.
