• Fretello — Made by guitarists, for guitarists, Fretello started as a simple app that our CEO, Florian, created as a companion to help him improve his skills. Seven years and many iterations later, we’re now the app of choice for guitar players of all levels who have a genuine thirst to improve.Driven by a belief that anyone can learn guitar, but noteveryone is taught well, we cut through the noise to give guitarists a comprehensive education that actually sticks. We know that proper learning takes time. We’re not here to simply teach you a few riffs and the odd song. We’re here to teach you how to really play your instrument. For us, the goal is mastery but with continual improvement. So, we’ve combined the insights of educational experts and professional musicians with advanced AI technology to create a truly innovative learning tool. That’s why we offer a structured Learn Path alongside tailored practice plans, daily guitar workouts, a large song library, and interactive jam sessions. We tackle playing guitar from every angle because that’s how confident, versatile guitarists are made. As passionate musicians, we count being able to express ourselves through music as one of life’s greatest joys. Whether with or without us, we hope you find a way to experience some of that too.
