### 4/5 — Great for a checklist!

*2025-01-15*

Great for a checklist. I do agree though that common names would be helpful, along with a geographical filter tool. Worth the money for me though!

### 5/5 — App for all Nudibranch enthusiasts!

*2012-02-28*

Another highly recommended App for all Nudibranch enthusiasts! 
Professionally produced, providing interesting and useful information. 
Nudibranch ID EPacific is easy to navigate and similar to its predecessor Nudibranch ID Indo Pacific has a range of excellent search functions to assist the user by simplifying the identification process. 
Excellent value for money!

### 3/5 — OK nudibranch app

*2011-12-28*

This is an OK nudibranch application for the Eastern Pacific. It is a bit difficult to use after a dive to ID nudis because: 1.) There are no common names; and 2.) There is no geographic way of sorting species to view species in a specific area. Difficult to use as a "field guide," so I am not sure what nitch the app will fill.

Pacific Canadians and US divers will still need Behren's and Lamb's books to ID nudi's. Good start, but I would rather be able to sort geographically than by photographers (and I am an underwater photographer).

### 5/5 — Another awesome app

*2011-09-28*

This app is very helpful for identifying new Nudibranchs and easy to use. I can take it with me on every trip now. Love it :-)

### 5/5 — Excellent
