Honestly a great dictionary, but I teach Marine Biology and I would love for my students to have access to a full biology/ecology dictionary as well. But I still give 4 stars.

I think this is a super lovely app that explains everything very well for what it is. my only suggestion would be to make it where the other terms in the explanation that are complex enough to be in the definition are clickable and transfer you to them, simply so it takes less time, but i think it’s a wonderful and incredibly useful app.

I purchased this app to assist my high schooler with learning differences. She has terrible working memory and asking her to go back and find a forgotten term in the book can completely derail her ability to stay on task during more challenging assignments. This is the perfect solution. She is able to quickly look up a term and move on with the work at hand. Obviously if the issue is understanding instead of memory, she still has to crack open the text to get a full explanation of a term, but this is perfect for jogging her memory.

The only thing I don’t like about this app is that it doesn’t have as many definitions as I’d like, but it’s still a fine app.
