Marion's mobile apps are not all current, due to time constraints and the regularly changing requirements of Apple and Android platforms. However her portfolio contains a rotating mix of the following:

Woodchuck Rhythm App
A child-focussed rhythm-learning app. Part puzzle, part drum-machine and part game, this app has had upwards of 100K downloads!


Play-my-note
An app that allows you to play a score-like interface as if it was a piano - without needing to know the names of the notes or where to find them on a keyboard. Simply match pictures to input your key signature and clef, and you can hear the notes by touching them on the screen. This also has more than 100K downloads, and is useful for singers or all ages who don't play the piano, or to hep with understanding keys and notation for those learning an instrument.

Sight-Sing App
This paid app is based (roughly) on the Kodaly system, with newly composed examples that follow the western canon of music rather than the more modal and pentatonic folk idioms of the original. It functions as a sounding textbook - you don't need to be able to play the piano to learn to sight-sing, you just need to know where the keynote is and get a starting pitch. All exercises can be moved up or down, so that the keynote changes its visual position on the stave, and the exercises can be set to suit your voice type (Treble, mezzo, alto, tenor, baritone, and bass)


Tuning Workshop
An advanced tuning app mostly to help my students develop a better ear, this explores the effects of micro-tuning in a four part chord, difference tones and pure intervals.

Pianodiamo
In development, a jewel quest with the accidental effect of teaching how to read notes at the piano.

Diamominer
In development, a crazy look at the skills needed to pilot a spaceship where the controls are a-symmetrical, (with a secret dose of piano fingering skills on the side)
