It doesn’t work

I might just be being dumb but why can’t I tune it-when I go into the app it just comes up with an electric guitar and u can play the chords. For one: how does that tell me how to tune it. And for two: I play acoustic. I wish I could fine a free guitar tuner that actually works😭😭

Porn

This used to be my favorite tuner easy to use, but it’s not suitable for children because they sell advertising to people who sell either women or the clothes they wear their pornographic images

Easy peasy

I’ve been using this app for years and it’s very easy to use no matter what kind of tuning you need it is there. I use it definitely weekly or more. Definitely recommend
