Every guitar/bass player knows that they *should* have the fretboard memorized, but they don't because it's tedious and boring. Fret Pro can do all the hard work for you! With just 10 minutes a day, you’ll have the fretboard memorized in no time. It's easy and fun! SPEAK THE LANGUAGE OF YOUR INSTRUMENT Having the notes on your guitar or bass fretboard memorized is the most important step toward becoming fluent in the language of your instrument. When you master the fretboard, you can spend less time thinking and more time enjoying playing music. PLAYER HIGHLIGHTS - "I’ve had lessons on-and-off for 10 years, but never did the work of really knowing the notes on the fretboard. I didn’t think it really mattered. But now, concepts I slightly understood before are falling into place, and I’m able to communicate with my teacher in the same language. Recommended." - "I’ve been struggling to memorize the notes on the fretboard for awhile now. This app really helped me get the practice I needed!" LEARN GUITAR FRETBOARD FAST Fret Pro is the fastest way to memorize the music notes on your guitar fretboard. Using scientifically-proven spaced-repetition techniques, Fret Pro helps you memorize each note in the most efficient way. Practice sessions are organized in bite-sized chunks so you can practice as much or as little as you want! BUILD REAL MUSCLE MEMORY Fret Pro is a different kind of fretboard trainer. You build muscle memory and fretboard vision by playing notes on your *real guitar or bass*. FREE FEATURES - Play notes on your real guitar or bass (or both). The natural notes on your first two strings are FREE. - Track progress toward fretboard mastery - Use your device's built-in microphone (an audio interface) - Have your device speak the notes for screen-free practice UPGRADE FEATURES - Unlock all notes on all strings - Focus practice on a specific string or strings - Focus practice on natural notes only or all notes SUPPORTED INSTRUMENTS - 6 string guitar - 7 string guitar - 8 string guitar - 4 string bass - 5 string bass - 6 string bass - Mandolin - Guitarlele/Ukitar - Want something else? Contact us at support@fretpro.app TIPS - The Fret Pro app works best with an acoustic guitar or bass, or an electric guitar or bass with amplifier. It will also work for an unamplified electric guitar and bass in very quiet environments. - The app listens for you to play the correct note, but that doesn't mean you can't make things more exciting. Try practicing different picking patterns, techniques, and rhythms. - Use your favorite effects and pedals like delay, reverb, or distortion! We'll still recognize if you play the right note… though pitch modulating effects probably won't work :) - Try to visualize a fretboard in your mind as you play each note. Can you play each note without looking at your fretboard? - Use the String Focus in settings to hone in on a specific string until you know it by heart. Memorizing the notes on your guitar or bass is a great way to take your playing to the next level. Supplement your current music practice or lessons with ten minutes per day and you'll be surprised at how fast you learn the notes. NOTE FROM THE DEVELOPER Hi! Fret Pro is an indie app made by one guy (me!), who is deeply passionate about music. It is my top priority to build an app that is actually *useful*. There is no nonsense and no tricks to steal your time or money. I actually want the Fret Pro app to be so good that you can STOP using it because it served its purpose (helping you memorize the notes) and you don't need it anymore! Got an idea to help make Fret Pro better? Send me a message at support@fretpro.app! The app is under active development and I’m constantly thinking of ways to make memorizing and visualizing the fretboard faster and easier. Thanks so much for your support, feedback, and reviews!
