Scale Practice - Randomizer is a free iPhone app developed by Alexander Burdiss in the Multimedia category, specifically under Music & Radio. The app offers users three main functions: random selection of scale types from a predefined list, random selection from user-inputted scales, and access to scale resources such as images and descriptions.

With a wide variety of scale options including Major, Natural Minor, Harmonic Minor, and more, users can diversify their practice routines. The app also features arpeggio practice, resources for learning new scales, and the ability to practice randomly selected scales inputted by the user. Notably, the app does not provide feedback or listen to users practicing, focusing solely on offering a new sequence for scale practice sessions.
