### 1/5 — Not much of an encyclopedia

*2025-06-05, version 3.1*

Paid app, with poor information.

### 5/5 — Top Reef Aquarium Resource

*2022-03-30*

Super easy to navigate. Easy to read and plentiful information on reef animals. Great for beginners and all levels! Even includes location of the animals and references! Developer responded right away and may even improve it even further with an option to favorite! Would love to see corals added- then I would pay at-least $10!

### 1/5 — Poor knowledge and inaccurate searching tools

*2020-08-02, version 2.1*

Wouldn’t recommended it

### 4/5 — Sehr informativ

*2020-05-23*

Um einiges mehr Informieren als in anderen Apps.
Leider lässt sich die Graue Schrift nur schwer lesen und wenn man sich einen Fisch anschaut hat würde ich gerne zurück und da weiterschauen wo ich war. Aktuell ist man immer wieder auf der Fischhauptseite.

### 1/5 — No

*2018-12-22*

No - waste of money

### 3/5 — How do a get a refund

*2018-02-15*

I downloaded this app thinking it had a much more options when it has so I was looking to get my money back for it and I can’t seem to figure out how to refund it

**Developer response:** I am sorry that I didn't see your comment earlier. And I am sorry that the app didn't meet your expectations. I guess you expected a calculator app?
As a publisher I can't make a refund. You would have to report the app as not meeting your expectations and ask for a refund.
