Marine HD is chock full of information about the sea. Unfortunately, none of that information is new or original. Every entry appears to be lifted word-for-word from Wikipedia pages, which are free to anyone with a web browser. What’s more, the app actually makes it more difficult to get information available online. Marine HD presents the information as huge blocks of text that are very difficult to read. The little text that’s not lifted from the free web encyclopedia is littered with misspelled words and sentences that, frankly, make no sense.
For example, the sentence that greets you upon opening the app begins, “Life is not merely around us, there is life even in the most inospitos of our beautiful planet earth, as marine life, a world in which there is also an ecosystem, evolution, biology…” You get the point. If you want Wikipedia pages, don’t pay for the pretty background and information that won’t be updated. Just open a web browser.
