Great App!

I've been using GuitarTuna for about a year or more. I play guitar (electric and acoustic), mandolin, and mess around a little with an electric bass.
I have three electric guitars hanging on the wall, each with a different tuning. GuitarTuna makes it super easy and quick to check the custom tunings of each guitar. As I'm getting older, my hearing isn't as good as it used to be. It's nice to be able to quickly launch the app and check any number of custom tunings for any one of my instruments. I love the tools, especially the metronome (which I should be using a lot more often), it's very user friendly and accurate. If I only realized even half the features of this app, I would give it 5 stars.


This app is awesome! If you need an app that doesn't need WiFi to work, gives you complete accuracy, and is super easy? Guitar Tuna is the one! I have played guitar for almost 4 years. I am very picky in what I do, including the way I tune my guitar. I have used a Snark before. It's a high-tech tuner you stick on the end of your guitar. It is nice, but you need good lighting and it isn't always accurate. Before Guitar Tuna, I had tried other apps, but none as good as this. My favorite part, other then the tuner, is that you can learn guitar on the app. It's a great way to start off. I hope this helped, and I recommend you get Guitar Tuna!


I never give reviews on apps, however I've only been playing guitar for like a year off and on (about 4 months with out even picking it up) I found this app just to tune up my guitar and I've learned so much in just a little over the week I've had it! I highly recommend you guys give it a shot, beginner or expert, it will help. Granted I'm still in my early stages of learning chords and how to change smoothly from note to note and keep the strumming down well but I believe this app is gonna get me where I'm wanting to head! THANKS AGAIN!
