    I've been looking for a tuner app that reads in cents and not on one of those meters with a needle which I find difficult to read and which are often graduated in two cent intervals. I make concertinas for a living have to tune many hundreds of reeds a year. I do my final tuning on a Sanderson Accutuner which was developed for piano tuners and allows you to select the pitch you are trying to tune to. This is important since piano strings and concertina reeds are rich in harmonics that can fool a tuner that scans for the strongest one. That is the only fault I have with this tuner in that it doesn't allow pitch selection except for a few instruments. This tuner matches the reading on my Accutuner exactly . Both read to a tenth of a cent. I find it highly useful for my pre-tuning and doing the initial tuning chart for each instrument because it is fast and allows me to stop having to estimate the needle position on my old pre tuner. If it allowed you to select the note and octave to block other sounds, I'd consider it as close to perfect as it could be for my uses. For those who are looking for frequency readings. They may be useful for certain temperaments, but for the most part, all the common temperaments are available listed in cents. Cents also are a relative measure that means the same thing at C1 as at c8, while hertz measures are absolute, one hertz meaning one thing at 60 hz. and quite another at 7680hz. Perhaps a selectable readout would make the app even more versatile. Dana Johnson

  • Open g tuning wrong

    by Ekdenton

    They need to update this app and change the high E string to a D on the open G tune setting. It is incorrect as it is.

  • Groovy app

    by Blankety-Blank

    Good feature set. Offers many tunings for slide or open string style play. Seems very accurate. Worth the money. Large display, easy to read and easy to use.

  • Best tuner I've had

    by Tome1810

    I have purchased two Korg handheld tuners before, and they are both vastly inferior to this much cheaper app. The app is much more accurate and picks up on the sound longer. If you need a tuner, buy this one!

  • Great!

    by Roger Lessman

    The tuner is fantastic, the best I have used. I do have one problem, it does not always load. In order to get it to work properly I have to do a reset of my iPhone. Not sure what the problem is but the tuner is great otherwise.

  • Perfect!

  • amazing tuner

    by dxak

    It was AMAZING after using for 3 days in Tuner* Lite. I have five guitars, three traditional ones while two electrical ones. When I tuning with tuner* lite, my traditional ones can reach the detection accuracy at +_1.5 cents but electric once reaches as far as +-0.3 cents, really amazing . Then I get the paid version, So I don’t need any other tuner any more.

  • Awful app

    by bin82

    doesn't work at all!!

  • Orientation Problem

    by AlastairLC

    This App comes up sideways and upside down on my IPad. It doesn't reorient itself as almost all other IPad apps do, and has no way to adjust orientation. This needs to be fixed in an upgrade ASAP.
