### 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 👍🏻👍🏻🤟🏻🤟🏻♥️♥️

### 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 — 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

### 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.

### 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.
