How to tune your Guitar, Ukulele or Bass?
Chromatic Guitar Tuner helps you tune your electric or acoustic guitar with a high level of precision and incredible ease. You don’t need any additional equipment - it works with the mic of your device, you don’t even need your guitar amp - it will pick up your electric guitar or bass unplugged.

The are several modes you can use to tune your instruments:

Automatic Mode
You simply play each string one by one and the app automatically determines the string deviation and shows you whether it’s sharp (higher pitched) or flat (lower pitched) and in which direction to adjust it.

Chromatic Tuner Mode
Tune by Ear. If you want to train your ear there’s just the perfect mode for you. In Tune by Ear mode - Chromatic Guitar Tuner will play out each note for you so you can tune your instrument. You can then check it in automatic or chromatic note to make sure it’s tuned correctly.

Pitchfork (Tuning Fork)
The app also includes a built-in tuning fork (pitchfork with tone generator from 1 hertz to 22050 hz).

Tuning Presets
Take advantage of the built-in presets for guitar and ukulele tunings:

Alternate Guitar: E Flat (half step down), First Fret, Open C, Open D, Modal D, Minor Third, Drop D, Major Third and other drop tunings.

I've been using this for a few years now probably and it's pretty great. It has lots of tuning presets, more than I'd ever need myself but also has a 'free tune' setting where it'll just tell you which note you're closest to when you hit a string. I don't think it gets you bang on the note, but it gets you close enough that you can tweak ever so slightly by ear if necessary. The ads really are not that invasive either, and I'm happy to endure them for the sake of how handy this app is.

It used to be good. I used it all the time after my chromatic tuner ran out of batteries a year ago. But the recent update (with the new interface) ruined it. I just spend 20 minutes getting my guitar in drop C and it still very off. It does not recognise which string I am hitting, and the new UI is not clear when I am in tune or not. One second my string is to high,the other second way to low. With the old version setting my guitar in drop C took 3 miutes and was pretty accurate (always needed some manual tweaking but that is expected from a phone app). Get the old version back pls!

App won't open unless I agree to a 3-day trial of a $70/year premium subscription. Seventy dollars?! Every year?! For a guitar tuner app which I use once a month?! I was happy using the basic pitch detection feature occasionally in exchange for ads. But the new trial can't be declined, so this app is now useless for me. Supposedly you can cancel the trial after agreeing to it, but I have no idea if the app will then function as before, and I refuse to indulge this "dark pattern" UX bs. Bye.
