This is super cool, and the number of tools you've packed into a single app (metronome, tuner, recording, rhyming dictionary, chord prediction) is really impressive. Great job aiming to be a one-stop shop for songwriters - best of luck with the app! I'll definitely check it out the next time I'm writing a song.

This is a small thing, but hearing chords/music sounds in your demo video (not just the voice-over) would be great. Also... your demo really should be a song.
