It works as a guitar tuner. I was surprised. It's accurate enough that vs a real tuner, it's basically the same readings, so you really cannot ask for a better guitar tuning option, FOR FREE and that uses your phone to do it.

it's literally B O S S🏁.I'll eventually buy the hardware BOSS & Strabo clip-on tuners but right now this app is very, very nice. It looks exactly like the hardware version.the fact that Roland gives it away for free.in exchange for just informing us of their latest product news.totally fair & smart.no crazy spam ads.everything is clean & refined as you'd expect from Roland Japan

Please improve with a more natural guitar sound pitch, in different keys, also include other instruments like elect bass guitar, violin,double bass etc.Then I would consider more stars. Now it sounded like a Robot.

It does what it says... kinda. The tuner light jumps around like a drunk fly, which makes tuning anything a guessing game.

The tuner works fine, but I find it incredibly offensive when an app company feels empowered to demand I pay attention to such excessive notifications. I know I can turn the notifications off, and I know other companies do this too, but it still annoyed me to have 4 notifications lol
