TyroTuner is a rather simple but very nicely presented chromatic tuner app for iPhone and iPad that offers an easy-to-interpret display so that you can tune your guitar quickly and easily regardless of your level of proficiency.
There isn't a lot to say about this app because of its simplicity but I would like to commend the developer for the way they've presented it; I love the guitar head interface with the plectrum-shaped buttons - very cool!
What we have here is a simple addition to the Music category of the App Store that will make it very easy for you to tune up your guitar when you're in a hurry. All you have to do is select a string by tapping it and then play the open string on your guitar to see how out of tune you are.
This app uses your device's integrated microphone to detect pitch within a 5 centitone range, and you can very clearly see the bar move into the green center position as you adjust your string pitch up or down.
The interface of TyroTuner is definitely one of the best I've seen in an app of this kind because it offers a more tactile and relevant user-experience because you tap the string on the screen and then actually tune up that string on your physical guitar.
Everything about this app makes sense, and I would definitely recommend checking it out if you've used other guitar tuner apps with lackluster results, or if you're a beginner looking for your very first tuner app.
