BOSS Tuner

I'm a full time guitar player. I have at least 5 tu-2 in gig bags, studio, or rehearsal spaces. This is a great app version of the pedal. I haven't used a better tuning app. Roland couldn't pay me to write a better review. The quality of this app might compel you to go buy the pedal.

Best tuner I've ever used. Gets me any tuning I want. Is very accurate, and easily made me a better player by increasing my versatility. I can jump from drop C, D, half step, and standard in minutes. No invasive ads either. Just a god tier app.

I've been using this app for years and it quickly became my favorite tuning app. Not only can you use it to tune your instruments, but you can also use it for vocal tuning, pitch training, and strengthening your voice for speaking and singing! 👍😉👍

This is the app you want! And a Capo! (I recommend G7TH Nashville.) Perfect for beginners. When you get good enough to need a real pedal tuner, you'll know what to buy. (I seriously doubt I will ever need a pedal tuner.) It's very sensitive. It says my HVAC is out of tune even though I can barely hear it running. I set my tablet on my BOSS amp (looks totally cool!) and adjust the volume to bury the background noise.😎

Very good but better be by yourself and have nothing on in the room you're in cause it's very sensitive! Very accurate but if you have any background noise or person talking or breathing to hard its gonna pick it up, which is not inherently a bad thing but almost impossible to use In a crowded setting so better get a real tuner if you're play a gig somewhere!

There are some graphic placement issues; maybe they just don't scale well to big phone screens like mine. Besides that, the tuner functionality itself is very good! It's probably dumb to say, but the results after using it were much nicer than after using my actual tuner on the head of my guitar.

One of the best tuners out there,related to guitar tuna and other apps it's much better. Tho I would like it if the mic wasn't so sensitive because in jam sessions it's hard to tune while other people are doing things like arranging cables , setting up amps , etc.

The visual misalignment of this is seriously annoying. Is anyone ever going to fix this? It was fine when I first got it, but it hasn't been right for years. I keep because it is still a very good tuner despite the appearance, which I do my best to ignore. It's very distracting when I know what it's supposed to look like. I've been a nearly exclusive Boss / Roland user for something like 35 years and I consider your products to be among the best, but the TU-3 tuner is a disappointment.

After a four year hiatus from guitar playing I've just re-downloaded the Boss Tuner which I remembered as being the definitive tuner app with the look of the real pedal. Sadly there appears to be a miss alignment with the active information and the background image of the pedal which makes it difficult to read the information accurately. Looking through the reviews it would appear that this has been the case for sometime. I'd say that the app is now unsupported find something else.

This is pretty sharp, spot on accurate. I installed it after losing my clip on guitar tuner. I can tune by ear alone but like to check it is perfectly tuned, using an electronic device. To feel secure. I thought this would be hard and unreliable but it was easy, very accurate and trustworthy. No excuses for out of tune guitar playing. Bad enough playing wrong notes/chords, without adding out of tune guitar and probably off key, out of tune voice. Guitar in tune gets one fundamental thing right,

📌 BOSS Tuner is the only app that is ad-free and most importantly the only one that can be set to 'Hz' in the standard version. Version 1.2.0. This is the most honest app yet. Even Fender only offers 'Hz' adjustment in the Pro paid version, they are obsessed with money and don't care about musicians and music. Thank you Japanese B○SS (Roland)!

No use to me. Interface not great, and results inaccurate - some notes on my Yamaha digital portable grand piano (consistently accurate tuning of course) came up ok but others bizarrely shown as being some way off (by semitones, not just a little bit) so uninstalled. Ended up with Pano Tuner after trying several free tuners, that seems the best so far. I wanted to tune a Kalimba which is quite tricky, and BOSS just couldn't do it.

[Tip use an external microphone] I was expecting much less, such as some kind of pay wall, only being able to use less than half of the features, things like that, and yet I was actually surprised & impressed by this app. It definitely exceeded my expectations. I even kinda like the catalog that it comes with. Definitely could do with out it and it wouldn't be much of a loss in any way. I just hope that they keep it updated, since we're stuck with it. I also have it on more than one device. BOSS

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!

I got this app to tune my cheap acoustic guitar, and this actually does the job. I have the real tuner for my electric gear, for the record. I’d be willing to actually buy the app if that meant the notifications would go away. This is indeed a free app, but please give us a way to remove these notifications.

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.

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.

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.
