In this app's "TabNavi mode," information from tablature files (GuitarPro format) loaded into the app is transmitted to the TabNavi guitar via Bluetooth. The LCD fingerboard panel on the guitar neck displays fingerings and string manipulations such as bends, supporting your playing. Furthermore, the playback speed adjustment function and the repeat function for any section allow for practice tailored to the player's level, from basic exercises for beginners to advanced song practice for advanced players. In addition to the songs included in the app, you can also select and practice with GuitarPro format tablature files saved on your smartphone. Meanwhile, "ChordNavi mode" allows you to easily enjoy playing chords along to your favorite YouTube songs. Selecting your favorite song from the list plays the video, and the chord forms are displayed directly on the LCD fingerboard, guiding you through playing the chords. Even songs you've never heard before can be played along to! Whether you want to enjoy your favorite songs at your own pace, accompany a friend singing, or play someone else's favorite song... you can easily enjoy playing the guitar in a variety of situations. You'll be able to play songs you thought you'd given up on. Even songs you don't know, you'll be able to improvise chord accompaniments. Furthermore, in chord dictionary mode, the fretboard LCD guides you to the correct finger placement while voice guidance navigates you on which finger to use. You'll never have to worry about not knowing which finger to use or where to press. Guitarists will be able to realize their envisioned performances and rediscover the joy of playing the guitar. That's "TabNavi Guitar."
