Been using Pro Guitar Tuner for a couple months now. It’s basically an app that lets you tune your guitar using your phone’s mic. Pretty solid app if you’re into keeping your guitar sounding its best.
Here’s what you do: you just hold your phone near your guitar and it analyzes the sound in real-time to tell you if you’re in tune. And there’s also a feature where you can listen to samples of different instruments to help tune by ear, which is pretty cool. And it works for all sorts of stringed instruments, not just guitar.
Look, if you’re a guitar player, you’ll probably like this. It’s not perfect – the ads can get a little annoying if you don’t pay – but overall it does the job. Worth checking out if you need a quick and easy way to keep your guitar in tune.
