    By Issy🌙
    I never write reviews, but I’m upset. I’ve had this app for a few years now and it has been the #1 tuner app that I have used. I play uke every so often for my special need students so naturally I have to tune my uke. One day I open the app up and there’s a 7.99 WEEKLY SUBSCRIPTION FEE??? Excuse me? That’s over 400 a year. I can go on Amazon and buy a tuner for $7 and I have that tuner for life. I understand needing funding for the app but I’m disappointed at the unrealistic price. Uninstalled.

    Really loved this app! I had an old acoustic restrung but was having trouble keeping it in tune. You app made it so easy and even congratulated me when perfect! Was so pleased with the sound!
  • $7.99 PER WEEK????

    By KTroxell
    This app use to have a free function but now you’re going to charge me $7.99 per WEEK. PER WEEK. A digital guitar tuner is not worth $40 a month. Are you absolutely kidding me? This has to be a joke.
  • I used to love this app

    By NicolasCam
    This was a great app until just recently. I open the app and to use the tuner you need to pay 8 dollars a week! For comparison Netflix is about 10 dollars a month. Are you kidding me! You people are very greedy and I’m deleting your app.
  • Suddenly wants a $7.99 a month subscription!

    I’ve been using this for a while now, and today when I try to use it, it wants me to sign up for an $7.99 a month subscription! For a tuner! Deleted immediately.
  • Scam

    By thin diesel
    Immoral marketing tactics. They wouldn’t let me continue using the app without signing up for a free trial for their premium service, which automatically starts charging you $8/week. This scam I’m sure works on many people and I certainly do not appreciate it. Although the app is good I will never recommend it to anyone again. App works great though.
  • Makes you pay for things you don’t want.

    By uncle from man
    This used to be my go-to use tuner, but they have added lots of unnecessary features with a ridiculous subscription price. Everything is behind the pay wall. Freemium model would make a lot more sense, especially since there are other quality, free options.
  • Excellent
