Easy and accurate


I'm a beginner and it was a daunting task having to tune my guitar. Past tuners were faulty and inaccurate and sometimes I thought maybe I was doing something wrong, that I needed to know a technique. Yes, there is a technique but im learning right now. I didn't want to spend for a tuner if I wasn't using it right so someone recommended trying apps. So glad I pushed download on this app. It was super easy and accurate. I tuned my guitar for the first time!!

Phenomenal app for tuning instruments


This is a great app for tuning your instruments. It sounds great every time I'm finished tuning and it has lots of different tunings to choose from. However, I would like to see a way to save custom tunings that I make instead of having to scroll through the "all tunings" to find the certain tunings I want to use. Overall, I recommend this app for musicians all around!



After a frustrating night of downloading a numerous amount of tuners that were completely complicated this tuner saved the day! Not only is it easy to use....well that's just it. It's easy to use. You can tell if you're flat or sharp and adjust to your instrument in the pro version. Well worth the purchase.
