Dual Metronome & Tuner

A precise metronome and tuner for musicians. A clean screen, an accurate beat, and only the tools you actually use when you practice.

■ Precise metronome
· Absolute-time scheduling keeps the beat from drifting.
· Time signatures (2/4, 3/4, 4/4, 6/8, 7/8, 9/8, 12/8) and subdivisions (quarter, eighth, triplet, sixteenth, quintuplet, sextuplet) shown in proper notation.
· Tap tempo and Italian tempo names (Largo…Presto).

■ Polytempo (dual-BPM stereo)
· Two tracks at different BPMs and meters, sharing one start point.
· Left/right channel separation with distinct timbres, so both beats stay clear.

■ Tuner
· Real-time pitch detection from the mic (YIN), with a cents tachometer.
· Audio is processed on-device only — never stored or transmitted.

■ Practice tools
· Speed trainer, bar counter, random mute, polyrhythm library, wrist rest.

■ More
· Dark and light themes, Korean and English, portrait and landscape, background playback.
· Fully offline — no account, no sign-in.

· Save the tempos and time signatures you use most, and recall them instantly.
· No account, no login — your settings stay on this device.
