About this app

🎸 Fretium — Learn to play guitar

Fretium is the app that guides you from your first chord to the most complex progressions. It works equally well with electric or acoustic guitar: everything you need to start playing, practicing, and tuning, without an internet connection or ads.

📖 CHORD LIBRARY
21 essential chords, from the most basic to barre chords and jazz sevenths, with clear fret diagrams: which string to press, with which finger, and practical tips for each one.

🎯 PRACTICE MODE
A random chord quiz that adapts to your level. Mark each chord as "I played it well" or "I struggle with it," and Fretium will repeat the ones you find most difficult to master. Listen to the sound of each chord before attempting it.

🎵 SONG MODE
11 pop, rock, blues, and jazz chord progressions that automatically advance on screen to the rhythm you set with the BPM control. Perfect for practicing chord changes with real-time tempo.

🎙️ CHROMATIC TUNER
Tune your guitar using your phone's microphone. Real-time note and deviation detection, with animated needle and EADGBE standard tuning for reference.

📈 YOUR PROGRESS
Choose your level (Beginner, Intermediate, or Advanced) and Fretium saves which chords you've learned and how much you've practiced each one.

🔒 PRIVACY BY DESIGN
Fretium works 100% on your device. You don't need to create an account with a password, there are no ads, no internet connection required, and your data never leaves your phone.

Start your guitar journey today—one chord at a time.
