Great app for my lap harp

Great app! Makes tuning easy.

Exactly what I needed

We purchased a melody harp from Hearth Song and as with all string instruments, they come untuned. So, I bought the EZ tuner that was suggested--terrible! We downloaded another guitar app and struggled with getting that to be helpful. This app not only told me what the note should sound like on my harp, but also told me which direction to turn the little L-shaped tuner. And gave me a clear checkmark when I had reached an acceptable range. This app is great--simple to use & tuning my melody harp only took me 15 minutes after trying other methods for over two hours.

I never write app reviews but had to for this one. Got my son a Music Maker for his 5th birthday, and it was totally out of tune. I'm the least musical person ever and had no idea how to fix it, so I downloaded this app. Totally worth it! Easy to use (even for tone deaf people like me) and now my son's lap harp sounds wonderful. Thank you!
