About this app

Seabook is an app that makes it easy to find out what kind of fish, corals or creatures you've seen underwater!

First of all you can open the category you need: "Fish", "Creatures" or "Corals, Sponges, Plants". There are 78 identification groups of fish such as Sharks, Clownfishes, Butterflyfishes, Parrotfishes, Groupers, Jacks, Puffers and Filefishes, Frogfishes and many others. "Creatures" are grouped by Molluscs, Mammals, Echinoderm, Crustaceans, Reptiles, Jellyfishes and Worms. The category "Corals, Sponges, Plants" has a similar grouping: Corals, Sponges, Tunicata and Plants. The total number of groups and subgroups is 275, which you can open and identify the fish, creature or coral whose name you doubt.

The easiest way to explore is using our filters:
>> Select "Fish", "Creatures" or "Corals, Sponges, Plants".
>> Search by color, pattern, location, body shape, social behavior, tail fin shape, etc.
Or, if you know a scientific or common name, use the Direct Search feature.
>> Open the list of marine life that match the specified criteria and find the one you were looking for.
>> Enjoy the result: great photo, description, distribution, habitat, lifestyle, legal status, maximum size and depth, and more.

More than 1500 species among fish, sharks, rays, nudibranchs and other molluscs, crustaceans, echinoderms and etc.

Seabook is a great solution for diving safari: turn on offline mode and use the app even on safari or remote diving sites without an internet connection. To fill your logbooks about who you met underwater, you no longer need heavy books - everything you need is already in your smartphone.

Seabook is the perfect app for scuba divers, freedivers, snorkelers and aquarium enthusiasts who would like to discover what marine life they have met and learn more about them.

Overall awesome app - no account, offline mode, etc, but unfortunately let down by a very limited dataset for Japan, with only 21 fish and a couple of other creatures. With a more comprehensive database, this app would easily get 5 stars in my book despite requiring payment to unlock certain features and many entries. Perhaps to keep size down it could support downloading only the data for selected regions like many offline mapping solutions do.

hi Michael. thanks for the honest review. Thanks for your feedback, really appreciate it. Japan as a location will be fixed on my side, right now you can choose Japan North and South to see all creatures for Japan.

The app is great, however I cannot recommend it due to many species being locked behind a paywall which is a big problem if you're looking for an app with documentation of marine life. Basically a subscription paywall doesn't make much sense here. Ads being shown instead of fully locked content would be way better than this.

Thanks for your feedback. I'm looking for alternative ways to provide access for content (rewarded ads, for example). And one time purchase for lifetime access. There are also plans to make seabook completely free in future.

Have to pay to unlock information on over 50% of species, beautiful pictures though and presentation of the app, and it implys that it had a photo ID for coral but can't find anywhere to upload a picture just lots of pictures with some information on some of the species as previously mentioned.

Hi Bruce, First of all thanks a lot you had found a time to share feedback. We divide our application lifetime cycle into several stages. The second stage will include social network where you will able to share images from your dives. Suggesting new species and providing the description sounds good. Best.
