“FretGenius is the best fretboard trainer app I found… It offers a gamified experience that is addicting and actually makes me practice every day.”

“I have spent the last 2 years or so trying to memorize the fretboard using different techniques from YouTube guitar teachers, and they all only led me to memorize patterns and not actually learn the notes. After using this app regularly, I am pretty close to having the whole fret board memorized!”

“This app has been pivotal in my memorization of the fretboard notes. The play along with your guitar mode is extremely fun, and when you hear the synchronization with the chord you are playing on top of is beautiful.”

“I have been playing the guitar for an embarrassing amount of time without ever getting comfortable quickly finding notes on the fretboard. In just an hour I can tell I have already improved drastically. Wish I found this a long time ago.”

“Excellent approach to learning the fretboard. The play along version is a great way to build up recall speed on the instrument as well as train your ear to hear the correct notes. The phase progression is set up to be challenging enough but not so that it seems out of reach.”

“I started by using the free website then decided to buy the app… Absolutely worth it. The option to play the notes on the guitar while using the mic is amazing. The lessons on music theory are well done as well. Can't wait to keep unlocking levels.”

Free to start, with a free trial of FretGenius Pro. Cancel anytime and keep the free features and every lesson.
What is free, how the trial works, and whether FretGenius fits your guitar and your level.
Yes. You can use these features without a subscription:
These features are part of FretGenius Pro:
When you install the app, a free trial of FretGenius Pro starts. You can cancel at any time and keep using all the free features, including every lesson. You only lose the Pro features.
A free trial of FretGenius Pro starts when you install the app, so you can try everything before you decide. If you do not want to continue, cancel at least a day before the trial ends and you will not be charged. The free features, including every lesson, keep working after you cancel.
On Android you can also cancel from the reminder email that Google Play sends.
Yes. Google Play sends an email before your trial ends, with an option to cancel. The App Store sends notifications too. FretGenius can also send its own reminder if you turn on trial reminders in the app.
Yes. Contact [email protected] and we will sort it out.
Yes. If you only want on-screen quizzes and the heatmap, use our browser site fretboardquiz.com. To practice with your real guitar or use Play Along, Daily Coach and the learning paths, install FretGenius.
No. Note Finder, Name That Note, Interval Finder, Scale Explorer, the Heatmap and the lessons all work on screen. The microphone trainers and Play Along use your real guitar.
Yes. The Note Path starts with the open strings and natural notes and introduces new notes in short, focused steps. You do not need any music theory to begin. When you install the app, a few questions about your playing place you at the right phase for your level.
Yes. Even experienced players usually have slow spots on the fretboard. FretGenius finds them and helps you speed them up. The Interval Path also teaches interval shapes that most players never practice deliberately. Its lessons are free, and its practice is part of FretGenius Pro.
The learning paths support guitar in standard tuning for now. The standalone microphone trainers for notes and intervals (Pro) show only the note name or the interval and accept it in any octave, so they also work with bass, ukulele and other stringed instruments.
Yes. An unplugged electric guitar is quiet, though, so the microphone picks up more background noise. Practice in a quiet room with your phone very close to the guitar. An amp helps too.
Yes. You start with the natural notes. Once you have learned those, you practice the full fretboard with sharps and flats.
