AChorda turns the Circle of Fifths into a hands-on chord sketchpad. Tap chords on a visual harmonic map, chain them into progressions, and hear them instantly through a built-in dual-oscillator synth with ADSR, LFO, and filter. Switch between full chords, strums, and arpeggio patterns. No DAW, no setup — just sketch an idea and hear it move. Free version covers the core workflow. Paid upgrade coming — one-time purchase, no subscription.
