MusicToolKit

Metronome, Tuner & Recorder

Free · In-App Purchases

MusicToolKit is a simple, capable toolkit for practicing music. Five tools in one app: metronome, tuner, tuning fork, recorder and keyboard. Open it and start right away. METRONOME · Accurate clicks: no drift or lag, however long it runs · Accents, compound meters (6/8 etc.) and bar-by-bar meter changes (4/4 + 5/4 etc.) TUNER · A steady readout: the display doesn't jump around, so you can tune calmly · Piano-roll-style scrolling graph shows how your pitch moves TUNING FORK · Pick the note on a piano-style keyboard · Reference pitch can be set anywhere from 400 to 500 Hz and is shared with the tuner and keyboard. 415, 432 and 440–444 are one tap away RECORDER · Dual level graph (peak and average): clipping warnings make distortion obvious, so setting the level is easy · Lock button prevents accidental taps while recording. Levels are shown before you start · Saves as WAV / M4A. Open recordings directly in the Files app, or export via the share sheet KEYBOARD · A simple tap-to-play keyboard · Sine, square, triangle and sawtooth waveforms Tuning is equal temperament. For just intonation and other temperaments, see "MultiTuneKeys". Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

  • This app has not received enough ratings or reviews to display an overview.

• Using the tuner while the tuning fork or metronome is playing no longer cuts out or lowers the sound • With Bluetooth earphones, the metronome and other sounds now play in music quality. Recording and the tuner use the device's built-in microphone • When earphones are disconnected, the metronome, tuning fork and keyboard stop playing • Added a screen explaining the difference between Auto and Manual input gain in the recorder
