I downloaded a tuning app but never quite felt the Ukulele was in tune. Plus, it was just a hassle going through the motions of using an app. I have a guitar tuner as well, but the ukulele was more for my daughter who is 7 years old and I wanted something she can use. This clip-on tuner is PERFECT! The construction seems great, it's easy to use, and it provides 3 tuning options that are easily to navigate through. I would recommend this to new entry players as well as seasoned professionals.
