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.
