"body": "So I play ukulele and guitar. No base. I got this because the other apps that I had for these instruments took up way too much space because they also included TONS of lessons and songs for not only uke and guitar but other instruments I’ve never laid a finger on. This would be great if you were a musical prodigy that played 15 instruments and sang but I just wanted a tuner. I have two electric tuners for both my uke and my guitar but I haven’t even put batteries in yet. (I’m a pretty lazy person when it comes to that sort of thing 🤣) I wanted something that I could get while sitting in my bed under three thick blankets with my uke under my arm and my guitar in it’s huge black case visible in the corner of my eye. (That’s where I’m at right now) I found this and it works as expected. And if you’ve read the reviews you’ll see that it is expected to be great. And it is!!! Great app!! Definitely recommend!!! So easy!!! No batteries!!! Deserves 5 stars!!! GET TO STAY IN BED!!!!",
