More than a Flashcard app, a complete tool for learning.
The best feature for this app, as an adult learner, is that, once learned, all memories are automatically refreshed together, as they are in our minds.
Your initial learning is like a conventional flash card. The spaced repetition is a separate act, easier, and more of a shuttle into your long-term memory as long as the memories can be refreshed correctly.
The latter point, the refreshing is where this app excels. Its a subtle difference, but very impactful.
Worth trying and buying, for any learner pursuing multiple subjects.
