Play as sea creatures in a coral reef ecosystem. Children control sharks, turtles, octopi, and starfish as they keep the ocean healthy in this virtual aquarium!

Play and learn about sharks, octopuses, sea turtles, jellyfish, and more. Discover how sea creatures live together in an ecosystem.

Coral Reef is No. 10 in Tinybop’s award-winning Explorer’s Library, a series of apps designed to introduce kids to big ideas. Other Explorer’s Library apps include The Human Body, Plants, Simple Machines, The Earth, Weather, Homes, Skyscrapers, Space, and Mammals.

Each Explorer’s Library app teaches kids foundational science. Kids learn by playing, observing, asking questions, making guesses, and finding answers. We hope each app inspires conversations between you and your kids and sparks more learning in the world around us.

Kids Like It!

My kids are 3, 5, and 10. They all love this app. I would love it more if the app had audio explaining everything since my two of my kids cannot read yet.

Light on substance

This app has beautiful graphics and interface like all the other Tinybop apps. But, what happened to the substance? I know that other Tinybop apps (like the Human Body), there’s so much information about what everything is and does. This app would be greatly improved by adding in descriptions of what are the different animals, why is it important what they do, how it’s critical for the environment and the health of our coral reefs etc. Voiceovers describing everything would be great.

I have a suggestion

Now I know you guys probably don’t take suggestions from fans all that much...buuut I may as well suggest you guys could do one about microbes like have a drop of water where you can place algae ameobas Cyanobacteria debris paramecia stentors and rotifers that all interact and I’ll leave the rest to you
Sincerely your biggest fan,roddy
