Apps like these are why open source exists. Clean, no ads, no cost, no background stuff and no internet required. Beautiful to look at and works perfectly. Less than 4mbs too

Great Tuner!

The only thing that is needed to make this tuner the best is an ability to connect to a DAW inside iOS. AUV3 functionality would be best for that, but even IAA would work at this point. I’ll keep my fingers crossed for an update, and I’ll upgrade my review if this happens, it’s the only thing missing from being perfect!

This is an essential, simple and absolutely wonderful app.

I love this app. No extra bells or whistles, it just helps me tune my guitar perfectly. Thank you, thank you, thank you!
