ChordLoop is the fastest way to find your next chord progression.
Pick a key, tap a chord, and hear it instantly. Stack chords into a progression, loop it at any tempo, and let the ideas flow. Whether you're writing a song, learning theory, or just noodling on the couch, ChordLoop turns "what sounds good next?" into a few taps.

Per-chord play styles (Pro)
Every chord in a progression can now play its own way instead of the whole loop sharing one feel. Tap the style button under any chord and choose Block, Strum, Arpeggio up, Arpeggio down, Arpeggio up-and-down, or Pattern — or leave it following the loop.
You hear each style the moment you pick it, the styles are saved with the idea, and exported audio plays exactly what you built.
Also in this release: the progression now shows numbered steps, and every control on a step is a full-size button.
