About GuitarTuna: Guitar, Bass tuner

Built by guitarists for guitarists and justifiably referred to as the “easiest, fastest and most accurate free guitar-tuning app out there”, GuitarTuna turns pro as it introduces highly practical, informative and user-friendly add-ons– no matter what your musical expertise.  Equipped for bass, 12-string guitar, mandolin, ukulele and banjo, as well as guitar, its outstanding tuner and comprehensive chord library – games to help you learn them – make this a must-have addition to any guitar player’s repertoire.

Teacher Review

Yousician Ltd. brings you its already extremely popular app ‘GuitarTuna’, boasting some 7 million downloads on iOS alone should stand as testament, not only to its popularity, but as a sign of how well it does its job.  As the title of the app suggests it is primarily a “tuna” (the colloquial phonetics of the word, rather than the fish).  However, even this basic feature of the app really is something that needs to be experienced.  It offers both manual and automatic approaches to a selection of standard and alternative tunings, which can also be customised to suit your specific needs.  The tuner is simple and easy to use, but more importantly it does this task to an astoundingly-high level.  The incoming audio is processed quickly and accurately, even with a lot of background noise, as the noise cancellation software expertly distinguishes what is being played by your instrument.  On this fact alone – especially considering that it is free – GuitarTuna merits its popularity.

With the ‘Pro’ add-on, however, the tuner is extended to the aforementioned stringed instruments, with the same accuracy and efficiency we see for the guitar.  On top of this the app enters into the realm of being an extensive chord library and gives its user the chance to develop their skills and knowledge of their instrument.  On initial exploring of the app, the user has at their disposal a comprehensive chord library of common major, minor, power, seventh chords, etc. with their derivatives alongside an easily recognisable fingering chart for each.  Having this, you can then practise what you have just learnt with the aid of the metronome, which cover a range of timing signatures in customisable tempos.  Yet, one add-on sees the app begin to back up the tuner with an introduction to basic chord structures.  The app employs a variety of competitive recognition games to help new and experienced guitarists alike to develop and hone their skills and familiarity with many of the common chords – focussing on the chords themselves, chord diagrams, recognising chords by ear, and then practically transferring this to your own guitar playing.  The format of these games make learning fun and easy, and the competitive element of trying to best your top score means you will keep coming back for more.  However, if it is an introduction to musical and/or guitar theory you are looking for, then this app will not fulfil your needs.

This bundle, at the current price of £9.99 for the full “GuitarTuna Pro” package, really is a great deal.  Even if you do not wish to stretch that far, the option of individual in-app purchases for the various add-ons means you can customise the app to suit your needs.  However, should you not feel the need for an app like this, there is no harm in having an extra tuner at your disposal – especially one that costs you nothing – and the quality of the signal processing that it provides will amaze even the most sceptical amongst its users.  For me – no matter what version of the app you choose – all that is left to add are these three simple words: download this now!
