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

Handy Piece of Kit

For those nights when regular turning is just a wee high, this comes in especially handy for dropping it to the “Dm 7 sus 4” of a full tone down expeditiously. Even laryngitis has a tough time beating that God’s blessings,
John.
(it also encourages alternate tunings; and, for people like me to delve into that, I need encouragement.

The worst.

The arguably the worst guitar app ever.

Weird ads distract from just enjoying the app

Every time I’m trying to use this app, weird ads are appearing at the bottom that are in really poor taste. It’s clearly click bait to appear like nude women and other suggestive stuff in order to gain attention. I’m just trying to tune my guitar man. Deleting and downloading something else.
