Greek and Latin Roots 4+

Solid UI, not stunning but an enjoyable enough experience. Some small additions could make this app much more effective:
There should be spaced repetition within each of the units, with a progress bar for mastery of each unit.
On the main page where all the roots are grouped together (separated into Latin and Greek) there should be an option to discard cards. Discard cards as in I don’t want to learn this root. The main purpose for learning roots is for greater understanding of English language and to figure out meaning of words easier. There are some roots that are practically never used in modern English and thus I don’t care to learn them (at least for now, maybe I’ll come back to learn them), but their grouped in with everything else. Another suggestion is perhaps different card packs like top 200 most used Greek and Latin words.
Otherwise a great app, 8/10 recommend.

There should be a way more options for the quizzes and an option where I can turn off the voice feedback

I purchased the app for learning medical terminology. I looked up pleura, visceral, and parietal. All are missing. I stopped right there and deleted the app. This seems to be aimed at a student learning elementary vocabulary. I give it two stars because it has glucose, implying content of a few other medical terms. Med students look elsewhere. The developer would do a service to consumers by clarifying the intended audience.
