What's New in Fretto

2.0

August 15, 2026

A new way to explore scales is here in Fretto! • Choose between the CAGED system (5 positions) and 3 notes per string — 3NPS (7 shapes). • Discover 12 new modes from the harmonic minor and melodic minor scale families. • Display each position directly on the fretboard, alongside the 5 pentatonic positions. • Better understand chords and scales with detailed formulas, notes, degrees, and intervals. • Enjoy more compact selectors, family-based navigation, and saved preferences. CAGED and 3NPS positions are available for 6-string guitars in standard tuning.

Amazing App!

I can’t believe this app isn’t more popular. It is exactly what I need and no other apps do it as well. If you’re looking for triads, Fretto what you need. Just select chord mode and make sure the triad option is checked, and you can easily change the starting string as well.

Response from developer

Thank you so much for your kind words! I really appreciate it — I built this app to be genuinely useful for musicians. The configurations are meant to be flexible so everyone can adapt them to their needs. If you have any feature suggestions or ideas for improvements, I’d love to hear them!

Absolutely Amazing!

Thank you to everyone that may have contributed to creating this app! So much information offered for free with absolutely no ads and no tracking(as of the time of this review). Maybe not the most beginner friendly but don’t get discouraged. Once you have even a basic understanding of the guitar, this will help you learn so much! I really wish I had this when I started learning 30 years ago!

Thank you so much for your amazing message! It really means a lot. I’m currently working on this app alone in my free time — it helps me deepen my own understanding of music theory too. If you have any ideas or suggestions to make it even more accurate or better suited to your needs, feel free to share them through the feedback section in the app!
