## What is Tone Craft?

Tone Craft is your all-in-one music practice studio for instrumentalists. Tuner, metronome, harmony, attack analysis, recording, and the newly added Scale Practice. Everything you need for daily practice, in one app.

【New: Scale Practice tab】

A fourth pillar of practice, alongside the tuner and metronome. Follow a score that scrolls across the screen while a reference tone plays, and practice long tones, arpeggios, lip slurs, and scales. Train accurate pitch and fingering with your eyes, ears, and fingers all at once.

- Accompaniment: every mode plays chord backing so you practice inside the right harmony
- Two-layer sound: the original range plus one octave up, for a full, rich accompaniment
- Record & play back: capture what you played and review it against the waveform

【Daily practice in one app】

- Tuner: high-precision pitch detection with low latency
- Metronome: irregular and compound meters, with a pendulum display
- Harmony: switch between just and equal temperament to learn beats by ear
- Attack analysis: capture waveform and spectrum the moment a note begins
- Recording: waveform preview and seek playback
- Scale Practice: flowing score, reference tone, and accompaniment to train pitch and fingering

【Pro-grade features, daily-touch UI】

The tuner tracks voice and instruments instantly with low latency. The harmony tab lets you switch between just intonation and equal temperament to hear the beating with your ears. The reference pitch and harmony now use a rich, dual-octave sound that makes those beats easier to hear.

【Themes】

Paper, Dark, Steampunk, Japanese and more — switch the mood to match your session (some Pro).

【Privacy】

All processing stays on your device. Recordings and tuning history never leave your phone.

【For】

Wind ensemble students, music college students, vocalists, brass and string players — anyone touching an instrument every day.

## Version history (last 5 releases)

### 4.6.1 — 2026-10-04

Tuner performance improvements: less heat, less battery drain.

• RMS computation accelerated with Apple Silicon SIMD (vDSP)
• Silent periods now skip processing to save battery
• 60fps needle animation isolated from SwiftUI layout for reduced heat during long sessions

### 4.6.0 — 2026-08-18

Added Etude pieces to the Practice tab.

• 6 Arban études added (No.11, 12, 13, 30, Syncopation No.1 & 2)
• Note values (quarter, eighth, half) now shown with noteheads, stems, and flags
• Improved metronome sync with the score

### 4.5.0 — 2026-07-19

Introducing the new Scale Practice tab.

A fourth practice mode, alongside the tuner and metronome. Follow a score that scrolls across the screen with a reference tone playing, and practice long tones, arpeggios, lip slurs, and scales — training accurate pitch and fingering along the way.

▼ Accompaniment
Every mode can play chord backing. Lip slur uses a pedal tone per valve group, blending naturally with the instrument.

▼ Two-layer sound
The accompaniment layers the original range with one octave up for a fuller tone. The tuner reference pitch and Harmony tab now use the same dual-octave layering, making beats easier to hear.

▼ Record & play back
Capture what you played and review it against the waveform on the spot.

We also shortened the countdown before the metronome from 2 seconds to 1, and fixed a crash when opening the Scale Practice tab on iPhone.

Thank you, as always, for your support.

### 4.4.0 — 2026-06-21

We refined the metronome pendulum and the harmony sound.

▼ A more authentic pendulum
- In odd meters (3/4, 5/4…) the downbeat no longer snaps back to the left every bar — it swings left and right naturally, like a real mechanical metronome
- Smoother motion through the center in "apex" mode

▼ Time signatures in one tap
- Pick common meters — 2/4, 3/4, 4/4, 6/8, 9/8 and more — with a button
- The numerator slider now moves smoothly and responsively

▼ A better harmony sound
- Chords are voiced more musically (the root grounded, the third a touch softer)
- A little added overtone gives the tone more presence and makes tuning beats easier to hear

▼ Tuned for iPad landscape
- The built-in metronome's play button now stays on screen

- Audio startup and overall stability improvements

Thank you, as always, for your support.

### 4.3.0 — 2026-05-31

The pendulum, now closer to a real metronome — and switches you turn by hand.
▼ A reworked pendulum motion
- In "edges" mode it now carries speed to the very end and snaps back, like a mechanical metronome
- The pendulum heads for the edge just before the click — that real, anticipatory feel
- Opens straight into "Pendulum, edges" out of the box
▼ Physical switches you turn
- Sound and view are now rotary switches you tap to turn
- On the Japanese theme, they become octagonal / hexagonal switches in lacquer-black and gold
▼ The pivot ornament turns and shines
- The ornament now spins in place together with the needle
- On the Japanese hex, the sheen stays oriented to your tilt even as it turns
▼ A pendulum in the Tuner and Recorder, too
- Switch the built-in metronome to pendulum view
Thank you, as always, for your support.
