### 1/5 — C’est nul nul nul a chi er

*2025-03-28, version 2.3.3*

Ils veulent juste récupérer vos coordonnées

### 5/5 — Ottima

*2023-05-25, version 2.3.1*

Chiede una conferma di registrazione da parte dell’azienda in quanto comunque da attivazione di un cancello / basculante, fatto questo è ottima, 
anche la possibilità di inserire una videocamera.

### 1/5 — La peggiore app mai acquistata

*2018-05-06, version 1.0.0*

- Registrazione nuovo utente quasi impossibile per mancanza di indicazioni sul tipo di password accettata
- Non memorizza le credenziali dei dispositivi associati
- Interfaccia poco intuitiva
- Istruzioni assenti o incomprensibili
- Grafica obsoleta
- Costo spropositato
Senza dubbio la peggiore app che abbia mai acquistato.

### 1/5 — Mot de passe

*2018-04-09, version 1.0.0*

Pour le login, le logiciel n’accepte aucun mot de passe, donc nul puisqu’inutisable.
