BOSS Tuner

Best free chromatic tuner for all instruments and voice

No way to report issues to support via App. 55 Badges that can’t be cleared. Deleting and reinstalling does not correct the issue.

Works great with iOS mics and external sound card inputs

Get the fender tuner app. That one works.

Such an iconic brand that can’t even make a working guitar tuner app, 10 years into smart phones, when every other lesser company can… yikes Download the Fender app, it works, if this even half worked it would be an improvement on what it is!

This thing fails at the one job it has.

It’s good sounds back to new when I used this app during quarantine I didn’t have a tuner so I found this app and had no problem with tuning

This tuner makes it almost impossible to tune your instrument. All the needle does is move back and forth randomly while I am trying to tune. Even when I’m not tuning it’s moving.

Installed the app and it’s got the red dot with 34 messages. Can’t clear them without opening every message that takes you to their website. One by one. No thanks Deleted

This app has not been updated for several years now. It’s only compatible if you have iOS 11 or older. iOS 15 is about to get released in a matter of weeks. This WAS is a quality tuner — and it still could be if BOSS updates it for the latest Apple certificates! It could probably also used a refreshed look on the UI/art to look a bit more modern. Please make this happen!
