Guitar Tuner FAQ

How to use

To tune your guitar in auto-tune mode, make sure the auto-tune mode is activated – the microphone button should pulse. Then just start playing the string you want to tune first. Make sure the pointer on that string is in the center of the string, so that the string name circle turns green. If it does, then the string is tuned correctly. Do the same for all the other strings.

Make sure the string you are tuning and the string in the app match, e.g. first string E1, etc.

If you want to tune the guitar manually, just turn off auto-tune mode by clicking on the microphone button to make it strikethrough. Then click on the string you want to tune manually and you will hear the string sound.

When the app uses a microphone

Our tuner only uses a microphone when it is open and visible on the screen, and only for automatic tuning. If you are having issues with the app listening to audio in the background, check if you have the latest version of the app installed. If you are sure you are using the latest version of the app, please email us at

Problems with tuning

We did our best to make an accurate tuner. To avoid tuning problems and to get the best result, we recommend tuning in a quiet place, not playing the strings at the same time, but playing them loudly.

If a string is too out of tune and sounds within the range of another string, there is no mistake that the tuner recognizes it as another string. If, for example, the 6th string is recognized as the 5th string, you should first lower it until it is recognized as the 6th string, and then fine-tune it.

For auto-tune mode, you can change the sound recognition algorithm in the app settings. You can also adjust parameters such as buffer size and detections per sec to achieve better tuning quality.
