Hyper Flow Piano

Hyper Flow Piano turns scale and chord practice into something you actually want to do. As well as many other practise exercises for learning the piano
Connect a MIDI keyboard, choose your key and mode, and play — the app gives you instant visual feedback on every note, so you always know exactly where you are and what comes next. No waiting for a teacher to correct you. No guessing. Just play, see, improve.
What you can practise:

Scales across all 12 keys and 7 modes, plus harmonic and melodic minor
Arpeggios and chord inversions
Chords and their voicings
Ear training for intervals, chord quality and modes
Harmony Scales — an exercise mode that combines left-hand scale degrees with right-hand arpeggios, with visual bloom animations as you play

Built around ABRSM grades
Every scale, arpeggio and chord is mapped to ABRSM grade requirements, so your practice always counts towards your next exam.
Correct fingering, always visible
Proper fingering is shown for every scale in every key — so you build good habits from the start, not bad ones you have to unlearn later.
Why it works
Most people struggle with scales not because they lack talent, but because traditional practice gives you no feedback until something goes wrong. Hyper Flow Piano shows you what's happening in real time, so your brain stays engaged and progress happens faster.
Requirements
A MIDI keyboard or digital piano with USB MIDI output is recommended to use the app. Most modern keyboards are compatible. Can also be used with an acoustic piano but this is not as accurate.
