how swung is your track? groove number gives you the number. drop in a song, record a clip, or open the live mic — groove number listens and tells you the one thing drum machines flatten and great players bend: the groove. 50% is dead straight. ~66% is full triplet swing. most music that feels good lives in between, around 54–62%. now you can see it. and it's not just the number. what it reads • swing % — the hero. one honest number for how far off the straight grid the groove sits. • bpm — dual-estimator with an octave guard, so 174 never gets called 87. nudge it ×2 / ÷2 or tap the tempo to lock it, and the swing recomputes against the corrected grid. • key — chroma + krumhansl-schmuckler with a tuning estimate, shown with a confidence read and the runner-up key, so a close call never hides. four ways to see it • meter — the number, front and center: swing %, bpm, and key in one calm readout. • swing grid — the signature view. every onset plotted against the straight 8th/16th grid, colored on-time, late, or rushing. you can see the pocket. • spectrogram — mel-scaled heatmap, quiet to loud, low to high, with a frequency + dB scale. • chromagram — the 12 pitch classes over time, tonic marked. how it listens • a file you drop in or pick (mp3, m4a, aac, wav, aiff, flac) • a clip you record — it listens and stops on its own the moment the groove locks • the live mic — a running bpm + swing read in the room, with a VU level meter and a live spectrogram one more thing • groove → midi — export the groove as a midi clip, swing baked into the note timing. drop it on a drum track in any daw and it plays your pocket. built to be calm and honest • fully on-device. your audio is analyzed right on your iphone, ipad, or mac. nothing is uploaded. nothing is stored on a server. • no account. no sign-up. no ads. no tracking. • strongest on four-on-the-floor and electronic music. live, acoustic, and rubato material is harder — so groove number always shows its confidence and hands you the ×2/÷2 and tap-tempo overrides. wrong calls stay visible, never silent. one number for the feel of a track. plus everything you need to trust it.
