    I just downloaded this app and was trying to set up. But somehow it said payment successful and I didn't even know what I'm paying for. And there's no way to cancel the subscription in the app.
  • Scammers

    By SlashFnR
    this application never says that you have to pay until you download it, they are scammers and they make you waste your time
  • What?

    By cashu nut is not a nut
    Apparently I was being charged 8$ a WEEK for this app that doesn’t even work well, I don’t remember the darn thing ever telling me that I was signing up to a subscription, so I was being charged 8$ week and I didn’t even know. The subscription was canceled but only after I was informed about the subscription that went on for weeks without my knowledge. Not to mention I uninstalled the app but still got charged. Don’t get this, it’s a scam and doesn’t function well, your probably better off just using a real guitar and watching videos online about tuning

  • Not free anymore 🤬

    By Twotyerfryer
    This was my go to for tuning my guitar. I regretfully updated the app and now I get to use it as a trial for 7 days then I have to pay $8 PER WEEK??? I don’t want guitar games. I don’t want guitar lessons. I just wanted a simple app for a tuner. Developers, why not create a different app that has the games, lessons, etc. and leave this one as a simple tuner for free?
  • Love the tool

    By Samuel Goldstein
    Such a useful tool, use it all the time. So not worth 7.99 a week. Thank you but I would like $16 back. I feel completely taken advantage of and I would hope you will be quick in your response.
  • Fraud App

    By donaldcrews
    Do not download, auto charges you 7.99 a week. I noticed the charge on my credit card account and immediately called iTunes to have it removed. They can walk you through how to unsubscribe. Apple should not allow apps like this!
  • Hard to unsubscribe

    By k0487
    Yikes. They make it really hard to figure out how to unsubscribe. Not cool.
  • Charged my credit card

    By Dgdgimxaabkoexnd
    Don’t download this app, you’re required to put try premium for a trail period and your credit card info is required to proceed to the app. You can’t unsubscribe from the premium part of the app so it keeps charging your account.

    Can’t use this app without a free trial that you later have to cancel if you don’t want to end up paying for the app. At least advertise that the app isn’t free.
