About this app

Fretonomy is the ultimate educational game to learn the notes and chords on the fretboard of the guitar and other guitar instruments.

Practice notes, chords, scales, intervals, staff reading, and the circle of fifths in over 25 different games. Or even generate chord progressions to help with song writing!

There are 9 instruments available to practice on:

Guitar
7-String Guitar
8-String Guitar
Bass
5-String Bass
6-String Bass
Mandolin
Ukulele
Banjo

Choose your instrument and pick one of the many games available to you to practice the fretboard until you have mastered every fret and every chord pattern.

Customize your experience by selecting which section of the fretboard you want to practice on. Practice the first frets, a section in the middle, or the entire fretboard.

Many games are available. Choose how you want to train. Learn by simply matching random notes with the fret on the fretboard, or try something different with the Color Matching game!

Learn and master all kinds of chord patterns on the guitar with the Name Chord game. Choose which chords you want to practice on any section of the fretboard, and go at your own pace. You will learn to identify any chord pattern very quickly!

Learn how to quickly read notes on a staff in the Staff game. Choose whatever section of the staff you want to practice on, choose the staff type, and start training!

Or master the fretboard and staff at the same time in the Staff and Fretboard game. Select a fret on the fretboard that matches a note on the staff!

Explore scales on the fretboard of your instrument with the Scale Explorer game. Choose a root note, pick one of the 63 different scales available, and start memorizing your scale. Change the color of the notes on the fretboard to identify intervals easier.

View your progress as statistics are logged for each instrument, tuning, and fret. A heat-map is used to show your progress. Share your progress with your friends!

This app is wonderful. The one thing that would make it even better is if in the interval section, you could use other degrees of the scale (instead of just the root) as the starting point from which to identify other scale degrees. In other words, if the app incorporated MODES, it would be just about as perfect as perfect can be!

Can you add a mode that drills the notes? One that endlessly goes on. Random order. Dot on note ,After a set custom time, then shows the letter name with the sound and moves onto the next note. This allows people to sit with their guitars and say/play the notes on their instruments. Much better for learning than just with the phone in hand.

This is a truly impressive app. Not only is it easy to learn the whole notes on any set of frets, it's also easy to learn flats & sharps, scales, chords, intervals, circle of fifths and a lot more. I've been using lots of different kinds of software consistently since the eighties. This is the best user interface I've ever come across.
