I finally got my guitar tuned using the app I got! It took awhile and it was way more frustrating than I thought it was going to be. I learned that the app glitches sometimes (just like any other app), and that causes the tuner to act weird sometimes. I was ready to bring my guitar to school and start working on it in the band room, but now we're not allowed to leave class and go down there because of new rules. I'll have to learn more at home than I originally thought.
