The interface is simple and comes with a variety of tunings for guitar, including standard and open tunings, Drop D and 12-string. ToneTune has over 60 tunings for stringed instruments: violin, cello, mandolin, ukulele, banjo, lute and a whole bunch more.

There's a handy Notes page that lets you hear single notes and lists them with their frequency [to 2 decimal places] and MIDI note number [0-127].

The cheapest digital guitar tuner you can find that outputs tones is probably at least $15. ToneTune is a great app! I know it will come in handy for me.

4-1/2 stars

ToneTune is an innovative tuning application that lets you tune your instruments by ear fast. I am personally not an expert when it comes to music, but being able to tune my guitar is a big deal to me. Whether you own a violin, a tambura, or just a sangen, you are covered with ToneTune.

You are going to need a good headphone to get the best out of this app. You get 128 playable notes, and the interface is very intuitive, allowing you to find the right instrument or notes easily. You can also adjust the frequency, volume, and delay before play.

All in all, if you are a musician looking for app to help you tune your stringed instruments, look no further than ToneTune. No matter how popular your instrument, there is a good chance its covered by ToneTune (my Iranian tar was!). I highly recommend this app to anyone who's passionate about producing and playing music.

Perfect Pitch

Whether you use standard tuning or an alternative tuning method to get the perfect sonority for your stringed instrument, the fact remains that it can often be a time-consuming and arduous task to accurately tune your instrument. If you are a musician performing live, time is an even more precious commodity so being able to tune your instrument quickly and accurately is essential.

ToneTune to the Rescue!

ToneTune from Stanton Studio, LLC is a brand new iPhone and iPod Touch application that is the perfect, portable tuning solution that is very quick to use and fits in your pocket.

ToneTune is a multiple tuning fork that helps you to tune the strings on your stringed instrument to the correct pitch by ear without searching through hard-to-find books or the Web. The latest version has more tunings for instruments than other competitors and best of all, the user interface is more intuitive.

Need A Virtual Tuning Fork? There's An App For That

Cool iPhone app of the day: ToneTune, a "multiple tuning fork" that helps tune stringed instruments to the correct pitch by ear, "without searching through hard-to-find books or the web."

The application is loaded with standard and alternate tunings, (and) includes the bouzouki, the banjo, and the 4-stringed biwa (and that is just among the "B" listings). Retailing for $2.99 in the iTunes app store, it's a lot less expensive than a separate electronic tuner, and would be nice for carrying around tuning information in your pocket.

We have a viola player, a guitarist, and two fiddlers at our house, so I can see how having a tuner on your iPhone could cut down on arguments over who gets the pitch pipe. :-)
