Useful for voice and single-line instruments when you care about the pitch path, not just the note name.
What you can notice
See pitch movement instead of guessing from note labels
Fiume makes drift, stability, slides, and vibrato visible while you sing or play, so practice decisions get easier in the moment.
Pitch movement, not just labels
Follow the contour continuously instead of relying on a single note readout. Drifting sustains and unstable phrases stand out faster.
Useful inside real practice
Use it during long tones, phrase work, intonation drills, and vibrato control instead of treating it like a one-off tuner.
Starts in seconds
Open the app, allow the mic, and begin without installing software or creating an account.
Who it's for

Fiume is most helpful when the pitch path matters more than a single note label.
