Quinterval vs Capo Chord Transposer

Quinterval is an interactive circle of fifths including the display of the corresponding scales. A key in the circle can be selected either by touching the tonic or by turning the slider in the middle. The circle displays both the respective major and parallel minor scales. The display ranges from F-flat major (D-flat minor) to G-sharp major (E-sharp minor). A second slider can be used to move the visible circle section accordingly. The note names can be set between german, english or italian notation. The lower area shows the related major scale with its key signature. The first step and the sixth step with the corresponding minor scale are highlighted. The notes can be displayed with G-Clef, C-Clef or F-Clef. The accidentals can also be displayed before the individual notes. Additional functionality is available as an InApp purchase: - Display the notes of the parallel minor scale - Display triads with their chord names - Playback notes by tapping on them

Capo Chord Transposer is built for the moment when the singer changes key and you still want playable guitar shapes. Choose the original key and the target key, or paste a chord progression and let the app show the capo fret, concert key, shape key, and alternate capo options. Share a clean set card with the capo fret and transposed chord shapes, then save repeat songs locally so the same chart is ready for rehearsal, lessons, worship sets, or live use. Built for guitarists who want a fast answer, not a full theory suite. What you can do: - get capo recommendations for quick key changes - see the resulting shape key and transposed chord shapes - compare alternate capo positions from fret 0 to 11 - share a set-ready transpose card - save repeat songs and reload them on device - switch notation preferences without leaving the core workflow Why people pay for it: - faster and clearer than doing semitone math in your head or browsing capo charts mid-song - focused on one rehearsal job instead of a broad guitar reference app - one-time purchase with no ads, no account, no subscription, and no cloud dependency Version 1 is a capo and chord-shape tool. It is not a lesson platform, lyrics library, tuner, or song database.
