Awesome tuner
I’ve compared this with my other tuners and it dead on. Great product

Decent but no constant sound
I thought upgrading to pro would allow the tone to hold somehow but it’s just to get rid of ads. No real benefit to upgrading. Tuner is ok; can change frequency. Disappointing no tone hold option.

Use it to tune my piano - I LOVE IT
This is a great visual system to see drift and, if you have an old piano like I do, this tool does the job not may others can do. I’ve tuned many instruments with this app come to think of it, but I get great results on my piano which people usually pay for special tuners - you don’t need one with this app. Perfect tuning app I’m glad I found it.

Reference note adjusting
Can’t adjust the reference note. A c4 as the lowest note is very high for us bass vocalist. Dissatisfied completely.

Does exactly what it’s supposed to do.
Easily worth $5. Reliable fully chromatic tuner that’s always in your pocket. I use it all the time, it’s usually the most convenient thing.

Kind of Unbelievable
I’ve had many pricey pedal tuners in my life. I grabbed this because I needed a tuner quickly while I was away from the house.
This is, by far, the best and most accurate tuner I’ve ever used. It works with ANY instrument, including things tuned very low.
I’m going to get the desktop version too.
Hopefully someday they make a physical tuner with this software because I’d buy it in a heartbeat.

Inaccurate
Tuner says note is an octave higher than it actually is. Example is a note played shows C5 in Logic Pro but shows C6 in this app.

The best
I find this app incredibly useful and accurate for the kind of tuning I use it for, it’s worth every penny in my opinion, pro has no ads and there’s great value in a good tuning app. Also bonus of actual functionality with the watch

Updated app in nearly perfect!
Works fine on latest iOS (18.5). Best tuner for cello of several I’ve tried. Only issue I’ve seen is that the app freezes if it has been left running for a long time, such as rechecking tuning after an hour of practice. Simply close and restart.

Simply the best!
I tried so many tuning apps . I would have thought they all function the same aside from the ui but this one is just BETTER than the rest ! Tuning instruments is faster and more accurate than dedicated hardware tuners I’ve tried too. I use it for Banjo, guitar, mandolin, bass, cello, harpsichord and unconventional stringed instruments.

Easy App to Use Professionally
Many of us (orchestral musicians and soloists) use Tuner T1 Pro because there is a lime green screen that appears when your pitch is perfect or nearly so. That lime green screen is steady, and easily seen out of the corner of your eye so that the player can make instantaneous corrections, should the screen lose its greenish glow! Even that tolerance can be adjusted for the most accurate of intonations. All of my students now use this, partly because they have Apple products, but also because it is a pleasure to use!

Best acoustic guitar tuner for iPhone
I think this is the most accurate and reliable tuner on the iPhone. I occasionally check its accuracy against my Peterson Strobe tuner and my Korg tuner and it is remarkably accurate.
A feature suggestion would be to allow the user to save perhaps 2 or 3 favorite alternate tunings and have one touch button on the home screen.

Worth every penny!
This is a great app. You can tune the guitar strings that typically go sharp when pressed to just a shade below zero and clean up some intonation problems!!

T1 pro tuner app review
I love this tuner app! I give it 4.5 stars. The only thing that bothers me about it it the so called “live pitch graph lines” since they are excessively distracting. It would be great if they could be disabled. Additionally the most narrow setting for these lines is still way too wide. Other than that, it is a superb tuner app.

Good App, Strange Issues
This app has served me well throughout my orchestral and musical career!!! I love it so much and I am exceedingly proud to call it my favorite tuning app of all time, but there is a strange bug, glitch, or whatever that happens pretty infrequently but is highly inconvenient as it persists for a long time as it engenders itself.
At random the app will stop registering sound and act as if my microphone isn't on, no matter if the setting in the settings is on or off. The only solution I'VE personally found is turning off my sound identification, but after doing so the app is noticeably worse qua

Love it!! Great for tuning accordions!
This is my favorite app for helping me tune accordions. The user interface is clean and simple. I used the free version for a while and decided to support the developer by buying the Pro version.

Fantastic!
This is the best chromatic tuner app I have used, and I’ve tried most of them. I use it train singing, and it’s so cool and so functional.

Love it , just add lower octaves (for bassoon).

The most precise and flexible.
I’ve tried them all, and while I still prefer my Peterson StroboStomp LE pedal, as far as apps go the Tuner T1 Pro is the best!
Renato2024-05-31

None better. Period.
Still the best tuner I’ve ever used. It tracks and holds the pitch like no other. it’s also gorgeous on either iPhone or iPad. Never fails, when someone sees me using it they want to know the names so they can download it. The only app I use even more than this one is his metronome, which is fantastic as well. Do yourself a favor and download the software pack that includes all of the apps. thanks for keeping this great product going.
