Any important words?

I tried to use this app for my ap bio class and I had to look up 100 words for a study guide and it had 1 word. It was like chapters 1-3 of simple biology and it had 1 word. Its useless. When you scroll from the top to the bottom of the list in two seconds you know its too short of a dictionary. Needs more words. Alot more words.
