Why these apps exist
Hi, I'm Javier
I started building these apps for my private students, because I wanted their practice at home to be as focused and musical as our time together in lessons.
In a lesson, everything clicks. We work through a progression, find the fingering that fits the hand, connect one position to the next. Then the student goes home, and the week between lessons is where it gets hard. What exactly should I practise? Which fingers? How fast? Practice turns into playing the same few things over and over, or into not practising at all.
So I started writing small tools to send home with them: a loop of the chords we worked on, practice sheets with the fingering on every note, exercises that link the positions of a scale into one line, the way I learned to see the neck while studying jazz.
Two things changed straight away. In lessons, I no longer had to write everything out by hand, so we had more time to actually play. And at home, my students weren't practising “alone” anymore. The apps answer them in real time, with chords, bass, drums and a click that keeps them in time, so practising feels like playing alongside their teacher.
My students kept using the tools and asking for more, and over time they grew into four apps: Chord Loop, Fretboard Maestro, Fret Link and Riff Lab. Guitar Lab brings them together with step-by-step courses, so you get the same clear plan and the same musical feedback my students get, wherever you are and whatever your level.
