### 1/5 — Pas du tout gratuit

*2025-01-27*

Attention au moindre clic sur l’application vous allez payer

### 1/5 — Pointless

*2025-01-15*

In a world of free tuners why would I spend money on pointless features that should be in the app

### 1/5 — Unable to use

*2024-12-07, version 4.1.1*

The ads are so annoying and it does not allow to close so I was not able to use it

### 1/5 — 구매취소요청

*2024-07-07, version 3.9.3*

I can’t even use it!

### 1/5 — In App purchases

*2024-07-06*

It’s not clear, but it’s 3 separate $4.99 payments each just to access the settings, tuning fork and to make it ad free. And if you do pay it keeps asking you to pay again anyway. Ads are very annoying, and setting super basic.
