### 5/5 — Incredibilmente vera

*2023-06-28, version 2.6.6*

Fare una recensione, nn è facile, soprattutto xke quando se ne è entusiasti, si deve prestare attenzione ad esser credibili. Sono arrivato a Leo3 dopo diverse esperienze, come tutto iniziate con macchine fotografiche, GoPro, e diverse custodie per iPhone. Il giudizio è, semplicemente fantastico… funziona benissimo, mai un problema, e poi se hai necessità di informazioni, o supporto il Team di EasyDive è sempre a disposizione….!!!
Revisione annuale compresa ….. 
potrei entrare nel tecnico, ma credo che nn serva…. 
Inoltre mi hanno annunciato che prima dell’estate c sarà una nuova App…. Nn vedo l’ora di provarla ….
Spero solo che oltre alla nuova, lascino anche quella attuale…. Cosi da poter scegliere quale utilizzare ….

### 2/5 — Une appli fonctionnelle qui manque de réglages

*2022-02-13, version 2.6.2*

L’appli fonctionne et permet d’avoir le contrôle sur le   Smartphone (iso, ouverture…) mais il est impossible de visualiser les photos prises, il n’est pas possible de régler si l’on souhaite la visualisation de la photo après la prise, du coup on l’a à chaque fois. Et éléments plus important. Malgré le côté universel du boîtier, on ne peut utiliser un second téléphone qu’en achetant ou demandant une seconde licence. Si on décide de faire évoluer son smartphone, il faudra débourser pour toujours utiliser le même caisson.

### 3/5 — Bonne application mais manque la lecture

*2020-09-19, version 2.3.1*

Cette application fonctionne très bien avec le caisson Léo 3 smart. En plongée elle est simple à manipuler et permet de nombreux réglages (ISO, vitesse, balance des blancs, zoom, mise au point, bascule photo vidéo, résolution vidéo...)

Il manque une fonction de lecture au palier des vidéos et des photos enregistrées pendant la plongée, c’est pour cela que je ne mets que 3 étoiles.

### 5/5 — Bellissima app

*2020-08-12, version 2.3.1*

L’app rende il tuo iphone il tuo compagno di immersioni e snorkeling senza dover avere una macchina fotografica sempre appresso.. passare da video a foto e soprattutto poter controllare il triangolo d’esposizione con uno smartphone è perfetto.. ottima app..
