Needs Ecology Words

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.

Super useful

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 itโ€™s a wonderful and incredibly useful app.

Perfect for High School Science

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.

great

useful and easy to learn the meaning of scientific express

Why canโ€™t I add this app to my home screen in focus mode?

Iโ€™m a graduate student and would find it really helpful if I could check definitions while reading journal articles without being distracted by other apps. Unfortunately, this app doesnโ€™t appear in the โ€œallowed appsโ€ settings on focus mode.

Would absolutely rate it higher if this could be fixed
