If you know the notes on the fretboard, you can easily(with practice ofc) pick up the melody in any song, and build/reconstruct the chords from there to learn the song.

To me, it's easier to learn a song this way than by reading guitar tabs or notes.

This is actually a bug of tabs that you don't even care what notes are being played.

I think it is why so often I hear people play and the strings aren't even tuned. "Who cares, it is just numbers on a finger board game." mindset.

No one on any other instrument ever would say musically, who cares what the notes are.

Hi there Can you send me a screenshot and tell me what iPhone it is?

I see fretboard orientation as relying on multiple techniques: 1. Notes 2. Intervals 3. Scale patterns

Notes are not the only way to orient but they're a start. I'm planning on adding more modules about intervals pretty soon

If you know the intervals, then you know where all the notes are on the fretboard! You're like Monsieur Jourdain, who mastered prose without even realizing it.
