    I used to not want to play my guitar because tuning it was such a pain, but then I got this app and now it’s SO fast! I'll be with people and I’ll tune my guitar with this app then they go “woah that was fast!”. 10/10 recommend.

    Highly recommend. Has lots of related material for anyone getting started or more. New technology always seems to be added. Tried a few of the songs and the app moves based on your playing. Great for anyone. Have tested the app against other tuners and this app can fine-tune. Definitely download so you always have a tuner and song helper.
