This is really nice. There are a number of songs whose chords I can't find, and this one came up with (at the very least) a starting point for figuring it out.

This is really nice. There are a number of songs whose chords I can't find, and this one came up with (at the very least) a starting point for figuring it out. I like how it tracks the beat and shows the waveform, and I especially like having the video play in the bottom right so I can watch as I play. Very cool. The only nitpick is a copy tweak. Throughout the app the app refers to itself as "us" or "our" ("Working our magic") and then almost immediately after as "me" ("It takes me about 30 seconds.") You should consider unifying the pronouns so that either you're always using first person, or you're always using the royal "we". Otherwise, this is pretty rad. I can see myself using this to practice some new songs that come out.
