Amazing concept, needs minor improvements – Vocabulary.com Review

I like the website and the concept of Vocab.com, however, I am also using DuoLingo in parallel, and it reveals areas of improvement for this app. I encourage the developers and researchers to implement a better designed gamification system. There is also no longitudinal way to determine if one has mastered a word. The developers should embed a UI that allows the user to write and practice creating sentences or speaking.
