Seems nice enough but missing lots of species, at least for Malaysia. [response to developer]. initial ones from first dive that were either fully missing from app or missing from malaysia list: banded shrimp, barrel jellyfish, crown of thorns, sea bunny). Also pretty much no corals

Thanks for your feedback. Currently Malaysia has about 1200 species. Could you name some categories of species, or specific species that have to be added/extended first? This would be very helpful

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.

Honestly I like this App, it has Good GUI and Displays, but the reason why I left it 4 stars Because, I couldn't even Get the Name of the Species of a fish, I just needed the name of it,even it's premium I just needed the name of a creature, But Honestly impressed By this app, Great work 🙌
