Fmaj7
Am Dm7 G
Play a chord. Cadence validates it.
How it works

Your phone listens. You just play.

Cadence uses a custom ML engine to detect chords in real time from your phone microphone. Piano, guitar, bass — anything with harmony. No cables, no MIDI, no setup.

1
Play
Open Cadence and start. The app listens through your microphone. No external hardware. Just sound in the room.
2
See
Each chord appears as you play it. Hold it for a second — it commits to your progression. Change your mind — it quietly disappears.
3
Keep
Your progression builds itself. Cadence captures the audio, saves the chords, and keeps everything. Come back tomorrow — it's all there.
What Cadence does

Built for the moment, not the studio

Real-time chord detection
Custom ML model, 18 months of R&D. Detects major, minor, seventh chords and beyond — from a phone mic, not studio gear.
Harmonic suggestions
After each chord, Cadence suggests what could follow. Rooted in music theory, filtered by your mood. Not prescriptive — just possibilities.
Session capture
Every progression is saved with its audio. No manual export, no forgotten voice memos. The idea survives the night.
Mood filtering
Choose the emotional direction — melancholic, bright, tense, floating. The suggestions adapt to where you want to go.
Who it's for

Musicians who compose by feeling, not theory

"I play every night after work. Sometimes something beautiful happens and I forget it by morning."
Evening pianist — plays by ear
"I know what sounds good. I just don't know what it's called."
Self-taught guitarist — writes songs
"I've lost more ideas to Voice Memos than I've kept."
Bedroom producer — composes at night
Under the hood

18 months of R&D. Not a wrapper.

Cadence runs its own chord detection model, trained from scratch on real instruments in real rooms. Entirely on your iPhone — no cloud, no latency.
