### 4/5 — Hard to See Chord Letters

*2024-04-10*

The white letters on the chord scale are very hard to read.  They used to be black.  Still a useful app for me.

### 2/5 — Support?

*2023-08-23*

Have used this app sparingly for some time. I recently started using a low g ukulele tuning and upgraded to tune. Easy to do in app, should have checked to see last update was 3yrs. After upgrade the “dial” has no notes anymore which let you tune accurately. Especially when putting on new strings, now no indicator of what note in scale you are on.

### 5/5 — gostei

*2021-08-03, version 2.0*

eu gostei do app, ele eh fácil pra mecher, e tb fica afinado rapidinho

### 5/5 — Not sure why theres bad ratings, I love it

*2021-02-10, version 2.0*

I’ve been using this app for as long as i remember. its a great app, esp if you’re starting out and dont know a lot. the tuner is very simple and i even invested in paying the small price for all the different tunings of ukulele. i forget how much it was but its not bad its truly an investment. i hope they keep this app on here forever its my go-to tuner app :)

### 1/5 — Bad

*2020-07-11, version 2.0*

Used to be decent

**Developer response:** could you please describe what exactly you dislike from this app? This helps me to improve ...

### 1/5 — No

*2020-03-29, version 1.8*

This app was not very accurate for me... -_-

### 4/5 — Unusable

*2020-03-21, version 1.8*

Crashes every time I try to access the microphone.
———————-
Update to above review.

The developer has contacted me and assured me he is working on a fix for the iOS 13.x.x issue with the microphone.

I can’t ask for more than that. As soon as it is fixed I’ll make it 5 stars!

**Developer response:** my sincere apologies for the crash when tapping the microphone button.
It’s a known issue - since iOS 13, my legacy sound processing engines does no longer work, and the app crashes.
In the meantime, I’ve bee looking for a new framework in order to make my app work again. Fortunately, I did find one today!
Please be patient, it will take 1-2 weeks until I get published a new release of my app.
Sorry for the inconvenience!

### 5/5 — Favorite Tuner App

*2020-03-15, version 1.8*

This is my go-to. I’ve tried a ton of different ty era and none of them have the right sound. This one is perfect, it’s really underrated

### 1/5 — Inconsistent

*2018-08-12, version 1.8*

Worst app ever. It says it’s in tune and when I go back to double check it says it’s not!

**Developer response:** My apologies - I'll try to reproduce that: maybe there have been problems with background sounds?

### 1/5 — Don’t even bother

*2018-07-14, version 1.8*

I couldn’t even get on to use it unless I pay eight bucks a month for a subscription fee.

**Developer response:** There is no subscription fee: the basic tuner for default uke is for free, but you can upgrade in order to get more types of uke and frequency analysis.
