### 1/5 — Not user-friendly for a recreational no decompression limit Diver.

*2024-10-31*

I tried downloading this app to plan my dives, but everybody makes it overcomplicated.
This app is not user-friendly even for the recreational Diver that I am. You would think they would make a dive planner simple as using slates for recreational no decompression diving.
If you’re looking at trying to get nitro gas slates, you’re better off googling it and going from there this app is overly complicated.

### 2/5 — Changement de langues

*2023-04-01*

Je n’arrive pas à la mettre en français.

### 1/5 — Crap!

*2022-12-07, version 1.4.1*

Total crap!!

### 1/5 — Terrible

*2022-08-27, version 1.4.1*

Absolutely horrendous. Meant to be simple. Completely useless and not user friendly at all.

Such a shame.

### 5/5 — Vraiment bien

*2021-04-22*

Programe facile a apprendre. J’ai comparé avec un algoritme de shearwater petrel2 et c’est vraiment comparable par default. Beaucoup d’options. Je recommande fortement pour planificatuon plongée avec procedures de décompressions.
