Google Search now has a handy built-in tuner that lets you use the microphone on your phone or computer to tune a guitar, Android Police reports. To access the feature that was added this week, just search for “Google tuner.” The interface is similar to the dozens of guitar tuning apps already available. You play a string on the guitar, and Google records the note you are aiming for and tells you to “set up” or “set down” as needed.
Like other guitar tuning apps, it seems that the efficiency of Google’s tuner depends a lot on the hardware you use it with. My iPhone 12 Pro (via Safari) or Windows desktop with a Blue Snowball USB microphone (via Edge) had no trouble hearing and helping me tune an unreinforced electric guitar, but a more affordable Android device I currently reviewing (with Chrome), could not take it at all. Your mileage can in principle vary.
Like most other guitar tuner apps, I do not think Google Search’s feature is going to kill the market for dedicated hardware tuners from e.g. Basket or Boss. It is too dependent on the quality of the microphone in your device and there is no way to easily plug in an electric guitar to avoid having to worry about background noise. But if you need to tune in to a pinch, Google Search has now covered you.
