### 1/5 — meh

*2026-02-16, version 2.0.9*

Every time you tune, the apple watch screen turns off. And even if you manage to deal with that, the mic on the apple watch can’t pick up any acoustic guitar sounds. would work if it was plugged in an amp. so it’s not the apps fault. but the limitations of apple watch fails this app

### 5/5 — 좋아요

정확하고 좋아요

### 5/5 — Sooo useful!

*2025-06-16*

I didn't have high hopes, but this tuner is super accurate and more useful than I expected. When you play a note (or hum) obviously it detects the pitch. BUT I love the added feature that when you stop playing, it keeps showing you your last pitch played and its value. I'm seeing nothing but one star reviews recently, and they're all about issues downloading/redownloading. But the dev has answered all of them, yet they don't change their ratings. Give credit where credit's due, people. This app deserves a MUCH better rating!

**Developer response:** Thanks ☺️

### 1/5 — Rip off

*2025-02-28, version 2.0.8*

App never downloaded or showed up in the watch for transfer to my watch.

### 1/5 — The tuner is deleted

*2025-02-15, version 2.0.8*

I paid for this tuner app and now it is not there in my watch, also I am unable to install.

### 5/5 — Get Back Best Tuner Ever!

*2025-01-10, version 2.0.8*

Okay, this is for the Apple Watch only. That’s why I love it, but if you loose it let me tell you how to get it back! Lay your iPhone down. Go to the App Store on your Apple Watch, scroll down to the bottom and tap on Account, then Purchased. Now tap My Purchases, then scroll to Tuner and tap on the download symbol and you will have this great app again on your Apple Watch! This is an App Store problem and not the developer. I did not figure this out. I contacted the developer and received these instructions in about 5 minutes! Wow! Thank you for an incredible experience sir! Oh, if you don’t have it, buy it. It is worth a lot more money than what it costs!

### 1/5 — Tuner disappeared

*2024-12-16, version 2.0.8*

I purchased this tuner app a while ago. It disappeared and it does not allow to redownload it. Is it no longer available?

### 3/5 — Have to wear on right wrist to get it to hear properly

*2024-12-15, version 2.0.8*

It works. But I found I had to wear my watch in my right hand near the acoustic guitar for it to work well.

For $2 it’s ok

### 1/5 — its gone!

*2024-11-13, version 2.0.8*

dissapeared from my apple watch, but i used to love it

### 1/5 — How to install

*2024-09-12, version 2.0.7*

I just purchased the app. App Store showed the app is ”purchased”, but there is nowhere to find the “install” or the app shows on the watch app list.
