Thank you for this tuner! I just love it. There are no fancy "lessons" or skins to make it look like something else. This is just a plain and very well-designed tuner. I have been playing for over (oh crap, I'm old) let's just say I started as a baby and have played for 50 years. I have actual physical Fender tuners that cost about $50 when I bought them, but that seem to be affected by weather. Having more than a dozen guitars, I struggle to keep all in tune. Some do not get played with very often and need tuning when I decide to grab that particular one. Having tried other tuner aps, I have been disapponted with the tuning parts. This is a very refreshing design, it works like a champ, and I just tuned an older acoustic spanish guitar in the shortest time ever! The guitars actually sound wonderful, like all along none of them have really been in tune. WOW! I am blown away and will recommend this app to everyone I know who plays. Now I will have a tuner with me everywhere I go, because you never know when you will run into a guitar that needs playing. (and you don't want those hearing to yell, "Tune it or die!"). Thank you so much for the design and accuracy you built into this app. I am going to delete all the other apps I downloaded that disappointed me. This is the real deal.

Works great. Saved me a lot of time bringing a neglected harpsichord up to pitch. I know nothing about tuning keyboard instruments to the proper temperament but this app helped get the instrument close to playable condition in short order.
