Master the fretboard with Guitarr: tuner, metronome, scale & note trainers, arpeggios, ear training & fitness streaks—your daily guitar coach in one app.
Guitarr – Your Complete Guitar Practice Studio
Guitarr is the all-in-one guitar app for tuning, scales, note practice, arpeggios, and rhythm. Practice with an interactive fretboard, real-time pitch detection, and a daily scale challenge that keeps you consistent. Built for guitarists who want structure without the overwhelm.
Scale Machine
Learn scales across the whole fretboard. Choose any root note and scale type: major, minor, pentatonic, major and minor blues, melodic and harmonic minor, and modes (Dorian, Lydian, Mixolydian, Phrygian, Locrian), plus chromatic. Scale positions update as you change key. Use the built-in metronome or turn on Listen mode: the app listens to your guitar and only advances to the next note when you play the right one. Perfect for learning scale shapes and building muscle memory.
Note Machine
Practice single notes in every position on the neck. One note is highlighted; find and play it across the fretboard. With Listen mode on, you get instant feedback and the app moves on only when the pitch is correct. Great for note recognition and finger placement.
Note Dictation
The app says a position (string and fret). You play that note on your guitar, then name the note. Option to skip straight to naming if you are not playing. Builds the link between fingerboard, sound, and note names. Essential for ear training and theory.
Tuner
Tune with real-time pitch detection: note name, octave, and cents. Set your A4 reference (e.g. 440 Hz, 432 Hz, or any frequency between 400 and 500 Hz). Professional accuracy for practice and performance.
Metronome
Set BPM and time signature. Visual beat and steady click for rhythm practice. Tap tempo and home screen widget for quick access. Stay in time whether you are practicing scales or playing with others.
Fitness (Guitar Tracker)
Open from the flame icon in the toolbar. Daily Scale Challenge: one scale per day; play 5 correct notes in Scale Machine to complete it. Earn XP, level up, and build a day streak. Optional reminders keep you on track. Add the Daily Scale or Streak widget for one-tap access from your home screen. Stay motivated like with a language app, but for guitar.
Widgets
Metronome (last BPM or fixed), Tuner (A4 display), Daily Scale (today’s challenge), Streak (current streak), and a dictation widget. Tap any widget to open the app in the right place. Practice without opening the full app first.
