Welcome to use our tuner for free online. The app is fully chromatic and therefore the guitar tuner online does also support a variaty of stringed musical instruments. Click on any of the links below to read more about how to use the app for each specific instument.
Also, it does work both for electric guitar and acoustic guitar. If you are using a smartphone or tablet the guitar tuner app is best to use because the online tuner does not have smartphone support.

However, if you want to tune an electric guitar or any plugged in instrument you have to adjust the input source. Click on the button "Show Instructions", right below the tuner to read more how to change this setting.

At any time you can click the strings on the fretboard to listen to a reference tone. One common way of tuning the guitar by ear is to tune the guitar to itself. If you are a beginner it can be a good practise to use a combination of a reference tone and a guitar tuner. One thing to notice is that the online guitar tuner does not show the actual octave. For that you need to download the smartphone app, which at the moment is of much higher quality than the online app.
To get the app to listen to your playing you will need to have flash installed and allow microphone access. See further instructions directly below the tuner by clicking the button "Show Instructions".
If you have any suggesions or think any other alternative tunings should be added, please send us a note through the guitar forum.
