You may already be aware, but having a small clip-on digital hardware tuner you can use anywhere without involving a phone is a life upgrade if you're playing guitar on a regular basis.

Of course, this is a cool project for more insight into the technologies involved regardless.

Yah, I keep meaning to get one of those, just haven't remembered to do it. And I'm super bad at guitar, so probably not playing anywhere outside of my basement for a while :P
