### 5/5 — Good

*2026-05-22, version 1.0.5*

Good

### 1/5 — Te roban tu dinero, ten cuidado

*2025-01-24*

Yo quise usar la versión de prueba y en ninguna parte de la aplicación puedes dejar la suscripción por más que busque e intente y acabaron cobrándome la mensualidad. Muy mal.

### 5/5 — Don’t like it

*2024-09-22, version 1.0.5*

I want a refund

### 1/5 — Review requested too soon.

*2024-07-31, version 1.0.5*

Only 2 steps into the setup and being asked to rate the app. How do I know if it’s good or not? Low score for not waiting until I use the app to ask for a rating.

### 1/5 — Es ist möglicherweise für scam gemacht.

*2023-10-03*

Man baut eine App, man baut Bezahlfunktionen ein, wie 5.99 Euro pro Woche. Es fehlt dann noch Marketing, um zu fischen. Es gab früher Telefon Diler , installierte Toolbars und etc. Heute gibt es solche Apps wie diese, mit AppStore als Billing Partner.

### 1/5 — Froze my phone

*2023-09-01, version 1.0.5*

Terrible!! Never had anything like what this app did happen to me before - it froze - I couldn’t turn my phone off. Took ages to finally get it working - happened several times before I got it deleted!!

### 1/5 — Dimous plumbing

*2023-06-21, version 1.0.5*
