    It lets me know just the right note I have to hit. Since I’m a beginner at guitar ‘tis was very helpful.

    The controls for settings don’t advertise themselves, aside from that it’s a great tuner
  • I was charged without knowing it??

    By Aluna23
    I downloaded this app so that I could y’know, tune my guitar. It asked if I would like to try the free trial and I hit no. I usually never remember to cancel the subscription, so I just don’t use the free trials. Anyway, I got a notification a couple days ago that there’s been a charge to my paypal account. I didn’t think anything of it since I do have a subscription to Apple Music. I looked at my bank account earlier this morning and I see that there’s been a pretty good size chunk taken out. I start looking around and I see that this app took out $79.99 out of my account, and I never subscribed to anything!! I’m currently trying to get my money back and figure out how on earth this even happened. I also never linked my paypal account to this app, so I dint even know how this transaction ever occurred
  • Instantly enrolled for $79 a year?

    By Subvertio
    Come on developers....$79 a year? Instantly enrolling in a $79 a year tuner is really bad. I never got confirmation or approved the $79 amount, I just noticed I was enrolled when I removed the app. Pretty savage and sneaky. You can get two real world snark tuners for that price! Sheesh!

    I had the app for over a year with no problems. All of a sudden I see a chatge for $79.99! They automatically enrolled me in a free trial of some “Guitar Tuner Pro” 3 day trial then tried charging me for it when it expired. I NEVER subscribed to anything and they tried backdooring me with some outrageous charge. HIGHLY HIGHLY HIGHLY SUGGEST YOU STAY AWAY FROM THIS APP
