UcanTune: Metronome & Tuner

Metronome, tuner and rhythm training in one app. No sign-up, no ads.

· Beats are counted in audio samples - the tempo holds even when the screen stutters
· Lay a percussion backing and record a whole piece over it
· Play a phrase, stop, and it loops - then stack more on top
· Warm-ups and a 104-lesson course, with today's work on one card
· Pro is one purchase, not a subscription


■ A metronome that never drifts

• 20-300 BPM, tap tempo to enter a song's speed directly
• Any time signature: 4/4, 3/4, 6/8, 7/8 and more
• Four accents per beat: strong, medium, weak, silent
• 9 subdivisions: eighths, triplets, sixteenths, dotted, shuffle, plus a cycling
mode that changes every bar
• 5 click voices: Classic, Wood block, Clave, Digital, Soft
• Silent beat cues - vibration, screen flash, torch
• Speed trainer (Pro) - the tempo steps up on its own
• Conductor (Pro) - write a piece by bar (tempo, meter, ritardando, fermata) and the
metronome follows it


■ Guitar tuner

• Real-time pitch detection through the microphone, shown in cents
• 11 tunings, 5 instruments; chromatic + transpose (B♭/E♭/F/A) for winds
• Reference tone mode - the app plays each string. By ear, no mic needed
• A4 reference adjustable from 435 to 445 Hz


■ Rhythm training

• Today - your warm-up and today's drill on one card, one button to press. Stuck twice
and it steps back; finish it and One more follows
• 104 drills in 13 chapters, two tracks - Rhythm and Solo. Full list under Course
• Rhythm - beats, eighths, triplets, chord changes, scales
• Solo - move one lick across A7, D7 and E7; fill eight bars with three notes over one
chord; then a 12-bar blues on your own, not judged - you hear it back over the backing
• Press for an example, different every time, lit on the fretboard
• Play the guitar instead of tapping - the phone listens
• Chord changes - land C to G on the beat. It judges the timing, not the chord
• Every tap judged in milliseconds, scored with points and stars
• If your timing leans one way, the result screen says so and offers to apply it -
earphone delay drifts, so measuring once is not enough


■ Warm-up - before you play

• Routines for acoustic, classical and electric guitar - 10 or 30 min
• Steps advance on their own with a vibration cue
• p-i-m-a finger order, chords and stroke directions follow the beat


■ Record · backing tracks

• No time limit - one piece or a whole rehearsal
• Percussion backing while you record - shaker, cajon or a rock groove, up to three
layers. The count-in hands straight over to the groove
• Import backing tracks and practise over them
• A-B loop - mark the hard bars and repeat, imported tracks too
• Slow to 0.5x / 0.75x, pitch unchanged
• Share through the Android share sheet


■ Looper

• Add percussion - rock beat, shaker, cajon, tambourine, claves
• Stack two more passes on top - lay the drums, then play over them


■ Practice history

• Daily streak, total time and recent sessions


■ On your Galaxy Watch

Tuner, metronome and practice coach run on the watch itself (tuner needs Watch 6 or
newer). BPM, tuning, A4, transpose and time signature sync with the phone, and the
downbeat is marked in sound and vibration. Watch audio is never saved.

Watch face complications: metronome, tuner and practice.

Install it from the Play Store on the watch itself, or from this listing - open
"Install on more devices" and pick your watch.

UcanTune Face, the watch face that opens the metronome and tuner from the dial, is
still in closed testing - email the developer to try it.

• English and Korean (other languages open in English)


■ Permissions

The microphone is used in the tuner, in Record and in guitar mode. The tuner and drills
discard audio as it arrives; Record writes a file only while recording, into the app's
private folder. Nothing is uploaded.
Decline the microphone and the metronome, tap tempo and reference tone still work. The
notification permission only shows playback state.
