Customer Reviews
Excellent in-depth presentations
This is a wonderful assembly of quick facts, photos, lessons, and scientific papers, presented by an array of experts from around the world. You can use it at any of several levels. I hope to see similar offerings from other fields as soon as possible. Young and youthful scientists - you should be working on one of these! And the application could easily go well beyond science. Congratulations to the entire team!
Really good app
This app is very informative and helpful. I am a studen currently in my last year of high school and I am planning to be a marine biologist so this app will help greatly. Also I read the article on this through Pulse and loved the effort it took to get this on the App Store
