The Easy Circle Of Fifths app is a free Android app for viewing the circle of fifths. This is a really compact app for your Android phone or tablet that displays a picture of the circle of fifths. This compact app can be viewed both in landscape and vertically and is visible on both Android phones and tablets. For this app you might have to have as much as Android 6.0 as the app is sort of new (by looking at the template). The app is really easy to use, you can just click the icon and it will open up right away, after which you can see the picture of the circle of fifths. What would be a more compact alternative for the basic circle of fifths, would be to just download a picture of it and keep in in the gallery in a folder only for it, so that you can view it all the time. The Easy Circle Of Fifths app is a really useful Android app for viewing the circle of fifths and can be used to make songs and learn music theory, as well as in order to hear all the scales of the notes you click on.
