You can display the circle of fifths in its "traditional way" in the "Scales" mode of the app. Then, only root notes and minor relatives are displayed. A "Minor relative" is the corresponding minor scale for a major scale.
For example, the relative minor scale for "C Major" is "A minor". Both scales have no accidentals. Meaning they share the same tonal material.
This way, you can quickly see which relative minor key belongs to a major key.
