Fret Trainer is the ultimate educational game to learn the notes and chords on the fretboard of the guitar and other stringed instruments. There are 6 instruments available to practice on:

5-String Bass

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!

Fantastic tool!

This is the first app review I’ve ever written, I just had to show my love. I downloaded this app 4 days ago, have put about 6 hours into it according to the stats, and I’ve got all natural notes up to the 12th fret pretty well memorized within a 1-2 second reaction time. If you break it up into chunks as you go and find little tricks to recall the notes, the app provides the random repetition needed to really commit it to memory. Having modes to both name the note shown, and find the note named, ensures you understand the fretboard both ways.

The scale explorer has been helpful to find patterns, and I’m sure it will be way more helpful as I continue with the app. I haven’t found the chord game to be super useful honestly, but still the $2 purchase is paying off in spades. Well done, a must app for any guitar player.

I really appreciate the feedback and glad to hear you're enjoying it! My idea for the chord game came about from my difficulty in memorizing all the different triad patterns. I then expanded it to more than triads to include the more complicated stuff (dim7, M7, etc). I find it more useful if you turn off the "Show Root" option in the settings. Then you're forced to recall the chord shape, instead of kind of cheating by already knowing the root and pretty much being given the answer. Just thought I'd share that again, thank you!

Well Done!

I decided recently I want to learn all the notes of the fretboard and memorize as many chord shapes as I can and this is the perfect app to help me do it! Love the interface too, clean and easy to use.

My only suggestion would be this. For both "name note" and "color match" the zoom feature is rather limited. It works well with a selection of 5 or so frets, though when I adjust my selection to frets 1-12 and put zoom on I am still shown 21 frets of the fretboard. If you could make the zoom focus in on the specific frets selected in settings that would be awesome. Other than that I'm very happy with the app!

Hey noahfy, glad you are enjoying the app overall. I know what you're talking about with the zoom and will see what I can do. Thanks! Edit: Hey again noahfy, I took your feedback into account and tried to improve the zooming in version 2.8. Please give it a try and see what you think!

Huge value for the money

Before finding this app, my quest to memorize the fretboard consisted of: creating a bunch of fretboard diagrams, making a bunch of copies, then repeatedly filling in the notes, over and over and over. Lots of reasons why this wasn’t the best most efficient plan, honestly. For one thing, it became too easy to just fill in the gaps based on the notes I had already labeled, which was sort of cheating, but unavoidable. All that being said, this app is PERFECT. I made more progress in three days than the two months before I started with it. Really can’t say enough. Thanks so much for making this!
