About this app

Metronome, tuner and a full set of exercises – everything you need to practise, in one clearly designed app. Whether it's daily practice, a lesson or the last minutes before a performance: keep steady time, tune your instrument accurately and train your ear, your note reading and your music theory. All in one place.

METRONOME
A precise timekeeper with everything you need for practice:
- Set the tempo precisely – with the slider, plus/minus or tap tempo
- The matching tempo marking is shown automatically (e.g. Largo, Andante, Allegro)
- Time signatures 2/4, 3/4, 4/4 and 6/8
- Choose your own accents: tap a beat to switch between accented, normal and muted
- Adjustable number of beats and subdivisions
- Adjustable volume
- Easy-to-read display with an animated pendulum

TUNER
A chromatic tuner that listens through the microphone and shows the exact pitch:
- Presets for guitar, bass, ukulele, violin and cello, plus a chromatic mode
- Cent-accurate display on a clear scale from −50 to +50
- Adjustable concert pitch A (default 440 Hz) – for ensembles and alternative tunings
- Note names with their frequencies at a glance
- Just turn on the microphone, play a note – done

EXERCISES – 13 TRAINING MODULES
Endless new questions, each in three levels: Easy, Medium and All.

Aural training
- Interval ear training – ascending, descending or played together
- Recognise chords – major, minor, diminished, augmented and seventh chords
- Hear scales – major, minor and the church modes
- Melodic dictation – hear a short melody and play it back on the keyboard
- Tuning & cents – tune an out-of-tune note by ear

Note reading
- Read notes in the treble clef
- Identify key signatures and keys
- Find notes on the guitar fretboard
- Build chords on the keyboard

Theory
- Name notes
- Match enharmonics (e.g. C♯ = D♭)
- Find keys in the circle of fifths

Rhythm
- Rhythmic dictation – hear a pattern and tap it back on the tap pad

After every answer you see the solution straight away, often illustrated on a keyboard, a fretboard or the circle of fifths. Your statistics – attempts, accuracy and streak – show you how you are progressing.

WHO IT'S FOR
For beginners and advanced players, for students and teachers alike. The app is deliberately simple and uncluttered, so you can focus on what matters: playing in tune, staying in time and building your musical understanding step by step.
