Can I use my Iphone to tune my guitar?
In late 2016, Fender officially released the groundbreaking Fender Tune app, giving players of all levels the ability to easily tune their basses, ukuleles and acoustic and electric guitars directly on their iPhones for free.
How do I check my guitar tuning?
Instead of using the strings to find the correct tones for other strings, an electric tuner will read and interpret the sound waves it picks up from your guitar and display in notes what it reads. Just turn on the tuner and strum the string. It'll tell you if your guitar is in tune within a few a seconds.
