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                     Iphone slow down Phil Phlorida

I looked at a dozen tuner apps It came down to Boss and Fender I loaded both and tried them a couple times The Fender app didn t like the low B string couldn t hear it well The Boss app performed well with all 6 bass strings The chromatic mode locked in quick to each pluck I turn my phone on it s side and set it directly onto the amplifier face This displays only the tuning graphics and they are large enough to read from floor level When using TU 3W black mode my phone remains discrete This is the next best option to an in line tuner                     Functional WorshipBassPlayer

Out of all the tuners I have this is the best Just have to get the real one for my pedal board                     Awesomeness Scarehaven

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                     Finest virtual tuner from the KING Boss Roland RossiDucatiDominatuon

There are so many other tuner apps that are way better such as ProGuitarTuner I d expect something more fluid and of better quality from from a company like Boss But I guess my expectations are too high     One of the worst tuner apps by far Lungho69

Not good go buy a real one     Boss Pedal Exodus Inc.

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                     Does what it says Eriptron

Screen goes into auto lock even when you re actively using the tuner That s just plain silly I don t want to have change my phone auto lock setting every time I use the tuner I m deleting this app until this is fixed     Auto lock warmlion

I ve used Boss tuners for years on my pedalboards Always great no fuss tuning I especially like my TU 3 with its nice array of LEDs makes tuning a breeze So obviously I was excited to find this app Very glitchy Does not track strings well even with the sensitivity maxed out Function buttons do not seem to do anything Not smooth and easy like the real pedal Hope they can improve on it TC s Polytune app is just like the real thing         Needs improvement Steve22222

Please make it so more pedals are available for the guitar iPhone connection and aux out to an amp Would love to have the discontinued DS 2 turbo to play with again                     More pedals SwimmingDem0ns

Played an open E followed by G Minor and the Hookers Came a Flowing on their 3 legged donkeys and thats when it got serious the E string broke and smacked the hoe in the face while Open E was in Sustain                     Boss Tuner Experience Spider757
