  • Predatory Subscription

    $8 / week for a guitar tuner? I was totally taken by surprise by the recurring fees as I do not feel I was notified appropriately.
  • Best app ever

    This is the best app I have ever used and it was free and it had helped me to get a better sound for my guitar so I could play it for a long day of church
  • Great! Easy to use.

    In about 3mins & with the help of my five year-old, we tuned her ukulele! So easy & fun. She can learn to tune the ukulele all by herself. Thanks!

    I love it. It’s easy to use. Not clumsy like all the other tuners. I just sit it beside me and it picks up the sounds. I don’t have to balance my iPhone under the strings.
  • works well

  • Subscription Scam!!!

    By denwood89
    I was in a pinch jamming with some friends and I had forgotten my tuner so I quickly downloaded about 7 tuning apps (because there are so many useless apps out there) before finding a decent one (I think it was the Fender Tuning app could be wrong). After the jam session I deleted every tuning app (because I own a tuning pedal that was about $20 and a snark clip on tuner that was about $12). Fast forward a month when I get my credit card statement and I have 3 charges from THIS APP for 8.47 because I allegedly subscribed by accident with absolutely no warning. This app is complete garbage for multiple reasons 1.) Who in their right mind would subscribe to a TUNING app? A tuner should be a one time purchase!! 2.) Why would I get charged 3 times in one month if I did for some reason subscribe to this app? 3.) why wouldn’t someone just make a one time purchase of a low end tuner for about 12 dollars on Amazon before paying $8.47 3 times a month for this garbage?
