### 3/5 — Decent but no constant sound

*2026-06-02, version 4.25.1*

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.

### 5/5 — 최고의 튜닝앱

*2026-02-01*

제목 그대로. 두 말하면 잔소리

### 5/5 — Simply the best. Lacking of a little feature

*2026-01-29, version 4.25.1*

Best tuning tool on the market. Needs “do, re, mi, fa” notation urgently

### 4/5 — 소리 노이즈

*2025-12-23*

음악이 업이라 5년이상 잘 쓰고 있습니다, 감사합니다.
한데 요 몇주 정도 전에 업데이트 하고나서, 음정 코드 버튼 누르면 음정 소리 나오는데 노이즈가 심하게 납니다. 지우고 다시깔아도 안되네요. 참고로 지금 쓰는 폰은 아이폰17프로맥스예요..혹시 이기종에서만 문제가 되는지 해서요..아무튼 해결을 부탁드려요ㅠ

### 5/5 — Does exactly what it’s supposed to do.

*2025-12-14*

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.

### 5/5 — By far the best tuner on the app store

*2025-12-10*

Just works, is fast, looks good. Fantastic.

### 3/5 — works great but absolutely crushes my battery

*2025-12-09, version 4.25.1*

why the f does this use so much juice?

### 5/5 — Kind of Unbelievable

*2025-12-05*

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.

### 4/5 — Too slow

*2025-11-07, version 4.25.1*

The app was nice but too slow meaning the notes registered 2 beats slower. Everything else nice!

### 5/5 — Top

*2025-10-27*

Continue like that

### 5/5 — My favourite way to tune

*2025-10-11, version 4.24*

I love that I can see a running history of the pitch as opposed to just the current pitch like most apps. It allows me to tune in a noisy environment. I recommend this app to all my students.

### 5/5 — The best

*2025-10-03*

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

### 2/5 — Apple Watch版

*2025-09-17*

Apple Watch版のHz設定が変更できません。iPhone版はできますが、設定の連携がされません。Apple Watchでチューナー使いたくて買ったのに、ヘルツ設定ができないなら、買った意味がありません。

### 5/5 — The best

*2025-09-08, version 4.23.2*

It is very useful without the ads and with an extremely accurate  tuner. Beyond words. It helps me a lot to tune my cello and was recommended by my teacher. Thanks Bijoy!

### 5/5 — Highly recommend

*2025-08-30, version 4.23.2*

Awesome app. I tell everyone about it. Great checking purity of sound at 440hz and 432hz; and the degree of cents out! Well done

## Most critical reviews (10 lowest-rated)

### 1/5 — The worst runner

*2026-04-11, version 4.25.1*

The wires tuner ever

### 1/5 — Does not work

*2026-03-28*

It worked erratically for a few months now it’s not working on my iPhone 13. Nothing not even the preset notes. Just dead even after updating.

### 1/5 — Reference note adjusting

*2026-02-20, version 4.25.1*

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

### 1/5 — Inaccurate

*2025-11-26, version 4.25.1*

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.

### 1/5 — 更新后用不了了

*2025-09-24*

不知道是不是因为iOS更新26.1的问题，还是其他什么问题🆘

### 1/5 — Not worth the 5 bucks

*2025-08-07, version 4.23.2*

Not that much just a regular tuner

### 1/5 — Doesn’t work

*2025-01-27, version 4.21*

Fail

### 1/5 — it used to work; what changed?

*2025-01-13, version 4.21*

i upgraded to the paid version after the free version stopped working. it all of a sudden does not pick up any tone i play; i did not change any settings on my phone. can you please help? this was my favorite tuner before the malfunction

### 1/5 — The app _used_ to work.

*2024-10-05, version 4.17*

Used to be the best, most precise tuner out there for bowed instruments. Stopped working after Oct 2024 IOS upgrade. No response from developer.  Standard, Pro, and BT1 all stopped working.

### 1/5 — glitchy

*2024-07-26, version 4.17*

started glitching to the point where its useless

### 5/5 — What the world needs.

*2026-07-28*

A true quality one time purchase product, the one time purchase part alone already makes it one of the best.

### 5/5 — Extremely helpful

*2026-07-16, version 4.25.1*

This app has been helping me with my pitch matching and a great help in the musical I’m in. Thanks a lot!

### 5/5 — Novice Tuner

*2026-07-10*

I found the Tuner T1 Pro incredibly intuitive and much simpler to use than other tuners I’ve tried. Fine-tuning each string was surprisingly easy—just a matter of watching the meter on the app. I highly recommend this program for beginners. I gave it five stars because, beyond its effectiveness, it helped me save money on piano tuning. At first, the idea of tackling this task was a bit intimidating, but it turned out to be much smoother than I expected. Fine-tuning each string became almost enjoyable, thanks to the clear indicators on the app. I definitely suggest this program to anyone just starting out.

### 5/5 — Awesome tuner

*2026-07-05, version 4.25.1*

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

### 5/5 — Best Tuner Out

*2026-06-04, version 4.25.1*

Most Precise Tuner Out 👍🏻👍🏻🤟🏻🤟🏻♥️♥️

### 5/5 — 确实很好用

*2026-05-22*

这款我用了好多年了，一直在用，主要是调二胡的音准，确实太管用了，对我的帮助很大，希望越来越多的人喜欢它

### 5/5 — Rapide et précis

*2026-03-20*

J’ai beaucoup testé et cet accordeur est le plus pratique et permet d’être très précis sur mes guitares.

### 5/5 — Love!!

*2026-03-01, version 4.25.1*

I absolutely LOVE this app.  I’ve been using it for years.

### 5/5 — Use it to tune my piano - I LOVE IT

*2026-02-26*

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.

### 5/5 — Good Thanks

*2026-02-21, version 4.25.1*

Good Thanks ,really useful app and appreciate the people who made this into awesome app,Cheers.
