Description
Tone Craft is your all-in-one music practice studio for instrumentalists. Tuner, metronome, harmony (just vs equal temperament beat comparison), attack analysis (waveform and spectrum), recording with waveform playback. Five apps you used to juggle, now consolidated into one.
v4.1 is a large update shaped by lessons from a trumpet teacher's studio and the developer's own practice.
【Daily practice in one app】
- Tuner: high-precision pitch detection with low latency
- Metronome: irregular and compound meters, subdivisions
- Harmony: switch between just and equal temperament to hear the beating
- Attack Analysis: capture waveform and spectrum at the moment of onset
- Recording: waveform preview and seekable playback
【Pro-grade features, daily-touch UI】
The tuner uses the YIN algorithm for high-precision pitch detection. AVAudioSinkNode delivers 20ms low latency. Voice or instrument, it tracks instantly. Reference A4 frequency (440 Hz / 442 Hz etc.) is adjustable. Black keys can be shown as Bb / Eb / Ab — intuitive for Bb instruments like trumpet and clarinet.
The metronome supports irregular meters (5/4, 7/8, 9/8 etc.), compound meters, subdivisions (8th, 16th, 32nd notes), and triplets. New in v4.1: 2-beat triplet, a rare rhythm that divides 2 beats into 3. Custom-built because most metronomes don't implement it. Ideal for tonguing etudes and 3-over-2 polyrhythm practice, with a guide-beats on/off toggle.
Choose from 3 metronome sounds (Wood / Electronic / Claves) to cut through ensembles and classrooms.
A built-in metronome in the Tuner tab makes long-tone practice a single-screen affair.
The harmony tab lets you switch between just intonation and equal temperament to hear the beating difference. A unique training tool absent from most tuner apps.
The attack tab visualizes the waveform and spectrum of each onset, making your articulation and tonguing visible.
【8 themes to choose from】
Free (2):
- Paper: a warm default theme
- Dark: black background for long sessions
Pro (6):
- Steampunk: brass and vacuum tubes on wood grain
- Cat Paws: playful cat paw prints
- Dog Paws: clawed paws with a dog chasing the tuner needle
- Botanic: clovers and acorns in a deep forest
- Wood: wood grain and machined brass push buttons, vintage audio gear feel
- Wafu (Japanese): iridescent cherry blossoms on lacquer-black, with mother-of-pearl hexagon buttons
Each theme has dedicated play-button and beat-marker designs (brass push / vacuum tube / mother-of-pearl hex / clover, etc.). Some themes feature highlight reflections that move smoothly with device tilt.

What's new (v4.3.0)
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.
