Online Acoustic Guitar Tuners List

The first choice that I researched was Fender. They have an online app for iPhone, or Android as follows:


For iPhone:

Download Fender Tune, a free tuner app for ukulele and electric, acoustic, and bass guitars. Accurate and easy-to-use, Fender Tune is a top-rated tuner app for beginners and experts alike.

For Android:

Fender Tune is now available for most Android devices. Pitch perfect with an easy-to-use interface, this app is great for beginners and experienced players. With 22 free tuning options, you can find the perfect tuning for almost any song.


Tuner-online.com boasts the latest, fastest, and right way to tune an acoustic guitar. Tuning will be done with the free online tuner that works through a microphone on your device. Perfect for tuning acoustic guitars, it also works well with any electric guitar.


They offer a new guitar tuner with pitch detection. It is very new and may not work on all devices, although they are working to remove the obstacles very soon.  To operate it:

  • First, be sure that the microphone on your device is turned on.
  • Click “allow” when the message appears.
  • There may also be prompts in some browsers to allow the website to use your microphone.
  • It seems to work best with Google Chrome.
  • It may be difficult to get your computer audio to work with the device, again something that they are working to improve.


In order to use the online tuner:

  • First click on the tuning key of the note you would like to hear or click the “strum” button to strum through all 6 strings. This is perfect if you want to test the final result of the tuning.
  • The app defaults to standard tuning but you can select other pre-set alternatives that are available from the drop-down box, “select tuning sequence”.
  • For a particular string, click the tuning key to hear it.
  • You can even adjust each string autonomously via the plus-minus buttons next to each tuning peg.
  • Most guitarists leave the app set on “standard” and if you do this, just start open the app and start tuning.
  • Turn up the volume on your computer and play along with the tuner.
  • Tune the strings on your acoustic guitar until they sound the same as the corresponding strings on the online tuner.


They offer an online tuner that is also free, and it has microphone access. It can be used to tune an acoustic guitar as well as an electric guitar. With the online tuner, they encourage you to use your preferred method. You can either use the microphone on your computer or just match the notes that it plays for you.

Basics Of Tuning A Guitar With An Online Tuner

Here are several facts that you need to know about tuning your acoustic guitar. Learn the standard guitar string notes before continuing. They are as follows:

  • 1 string – E4 (the thinnest)
  • 2 string – B3
  • 3 string – G3
  • 4 string – D3
  • 5 string – A2
  • 6 string – E2

How do you tune a guitar?

  • Press the “turn on” or “power” button under the tuner.
  • Your device will ask for permission to record sound from your microphone.
  • Allow recording so that the online tuner will hear the sounds you make on your guitar.
  • Then play a strong. You can choose any string.
  • The chromatic guitar tuner will show what note it is and how accurately it is tuned.
  • If the tuner shows that the sound is not accurate, twist the peg and try to change the sound of the string.
  • When the note on the tuner turns green, the string has the perfect sound. Amazing!
  • Tune all of the strings this way. Follow the notes that are shown in the above list.
  • After tuning all the strings in order from the first to the sixth, or vice versa, test their sound in reverse order.
  • The total tension of the guitar neck can change when the tension of the strings is changed. As an example, if you tuned the first string but the others were not very tight after you have tuned all the other strings, the first one may be below the required level and, as such, will need to be tuned again.

How often should you tune your guitar?

Frequently, many factors can and will ruin the sound of your acoustic guitar. Some of these factors include:

  • Playing it
  • Changes in temperature
  • Humidity
  • Long term storage

Here is a rule of thumb that you can go by: Only one hour of continuous play can make it necessary to tune it again. If you play infrequently but haven’t tuned your guitar for a week, chances are it will need to be tuned.

It is easy for a guitar to slip out of tune due to the above-mentioned factors and also because the tuners on the guitar itself can easily be bumped.

Start tuning on the thickest string, the 6th string. Press down on the 5th fret and compare the pitch of that note to the open string above, the 5th string. It should be the same. If it is not, then tune the open string to the fretted note. When the 5th string is in tune to the fretted 6th string, go to the next string. Each string can then be tuned in this manner.


Today, guitarists like you have the option of using a free online tuner to tune their acoustic guitars. This has greatly simplified the tuning process. It is still good to know how to tune by ear and this skill will become easier with practice. Enjoy the learning curve!
