Finest virtual tuner from the KING- Boss (Roland)!

As a confirmed 'gear addict', I've spent the better part of 40 yrs in one of two states: playing guitar through great pedals and amps, or thinking about playing guitar through great pedals and amps- mostly always chasing tone! After amassing a pallet's full of data, and wallowing in the embarrassment of riches that is the modern music marketplace, I've secured the finest in every category for my time (mostly) without regard to price, and after all the latest data are exhausted, and the interminable researching & obsessing concluded that despite all this, 20 yrs on: BOSS TUNERS ARE STILL FLAT OUT THE BEST, ALL-AROUND TUNERS; and a non-negotiable for touring professionals, while equally as crucial to the rank beginner, and truthfully everyone else.

Iphone slow-down?

This tuner worked so well I was considering leaving my other tuners out of my guitar cases. However, a few months ago, I suddenly found that the tuner was off. It now registers my 440 tuning fork as about D#. Apple recently admitted it slowed down older iphones, which they may have done to my iphone (through IOS updates I installed?) and caused the tuner to read about 3/4 what it should. If you are going to load this on an older iphone, perhaps the IOS "updates" will screw it up.

Honestly, I can’t believe that Roland has graced us with this amazing app. It does a better job than a lot of things you would actually pay for. I know that it’s somewhat dependent on the quality of the phone you put it on, but on every iPhone I’ve ever run it on it has been fantastic.

For the reviewers commenting on fixing the Mode button. If you read the in app help it states that the two buttons are not functional. It's basically just a picture of the hardware pedal. You'll notice the 1/4 jacks on the side. They don't work either. ;-) The tuner works just fine!Oh, and TC Polytune isn't on the App Store anymore that I can find FYI.
