  • No updates in years

    Often spams you with the strum tutor app, forcing it to open in the App Store even if you press the X to close. Now iOS 11 is here, it’s not even functional anymore I don’t see it getting updated any time soon.
  • Update the app to 64 bit

    By suyashsrijan
    Please update the app to support 64 bit otherwise it will not work in next iOS version
  • Used to work

    So when I brought this app it used to work fine and it was the best app at the time, I have no idea why but it doesn't work anymore, tried to open it on my sister's phone to see if the problem was my phone but NO the app is not working anymore. Waste of money if you ask me 😓
  • Brilliant App

    By Paul Anant
    I use this several times a day in a professional capacity and have found it to work brilliantly and to be really accurate. Great app.
  • Guitar, Cello and Violin sorted

    Works perfectly on all our stringed instruments.
  • It works, but....

    By Colm Donnelly
    It is tremendously inaccurate, giving an inconsistent reading on a steady natural harmonic of up to +-6 cents.
  • Hmn

    By Ismellpoo
    Not a great app, it said all my strings were ok, but it sounded completely out of tune.
  • One quick question...

    By Jakedowen
    First of all, the tuner itself works fine; best one I've had off the App Store by a long, long way. But... WHY ON EARTH AM I STILL BEING BOMBARDED WITH ADVERTS WHEN I PAID FOR THE APP!?!?!? YOU'VE ALREADY HAD SOME MONEY OFF ME!!! AND YOU'RE STILL SNIFFING AROUND FOR MORE!? ABSOLUTE JOKE!!!
  • Works like a dream

    Does exactly what is says on the tin. Great tuner, easy to use, accurate. I'd recommend this to any player of any level.
