### 5/5 — Easy peasy

*2026-06-23, version 2.13.0*

I’ve been using this app for years and it’s very easy to use no matter what kind of tuning you need it is there. I use it definitely weekly or more. Definitely recommend

### 5/5 — Reliable

*2026-06-10, version 2.13.0*

This tuner is reliable for many many different tunings 🎸

### 5/5 — Handy Piece of Kit

*2026-06-07, version 2.13.0*

For those nights when regular turning is just a wee  high, this comes in especially handy for dropping it to the “Dm 7 sus 4” of a full tone down expeditiously. Even laryngitis has a tough time beating that God’s blessings,
John. 
(it also encourages alternate tunings; and, for people like me to delve into that, I need encouragement.

### 1/5 — The worst.

*2026-05-07, version 2.12.0*

The arguably the worst guitar app ever.

### 2/5 — Weird ads distract from just enjoying the app

*2026-03-20, version 2.12.0*

Every time I’m trying to use this app, weird ads are appearing at the bottom that are in really poor taste. It’s clearly click bait to appear like nude women and other suggestive stuff in order to gain attention. I’m just trying to tune my guitar man. Deleting and downloading something else.

### 3/5 — Simple

*2025-06-28, version 2.12.0*

Well done

### 5/5 — Essential

*2025-05-20, version 2.12.0*

If you play guitar, this is an essential simple piece of kit that you’re more than likely carry with you everywhere – even when you forget, lose or find a dead battery without replacement for your clip on tuners. Excellent job to whomever originated this app. God bless.

### 5/5 — Tonal help for aging ears!

*2025-02-12, version 2.11.0*

When I have no tuner and it’s quiet this is a great help!

### 5/5 — Love it!

*2024-12-21, version 2.10.0*

This is exactly what I needed!! Thank you! I wasn’t even sure what to ask for, I have quite a few guitar tuners but they all go from me plucking the string but I needed to be able to hear what the E string sounds like, then I can tune my guitar! Thanks again!! 5 star!!

### 1/5 — Doesn’t work at all! No sound comes out

*2024-12-15, version 2.10.0*

It worked fine before the update to iOS 17, but now it doesn’t work at all. Too bad because it was one of the better tuners out there. Hopefully the creator can get this thing fixed to work.
