Guitar Tuner! app review: a super simple tuner for your beloved axe



No 'axeman' can get by for long without a decent chromatic tuner, and this iPhone and iPad app provides just that, an incredibly accurate tuner with a bank of alternative tunings that you can use to tune up your six-string by ear or visually.

This is a fairly standard addition to the genre of guitar tuner apps but I think that the developer has done an almightily good job of providing not just the bare basics but a few additional extras such as automatic string detection and a very attractive interface design.

Whether you’re a complete newbie or a veteran, you’re sure to get some use out of this app, and for under a dollar I’d say you really can’t go wrong!

Tune Your Guitar to 1 / 100th of a Semitone

Guitar Tuner! is a basic yet wonderfully accurate chromatic tuner that you can use to ensure your beloved axe is always perfectly in tune, whether for at home practice sessions or actual live performances. The tuner is accurate to within 1 cent or 1 / 100th of a semitone, and it also features sub-second response time for even greater accuracy.

If you do happen to be using this app for live performances then chances are you’re going to be in a busy venue, so you’ll be pleased to know that you can deactivate auto-string detect for noisy environments such as this.
