▲ ▼ Anki accumulated reviews
Anki is a leading flashcard application used extensively by students for learning new languages to medical courses. It uses scientifically proven spaced-repetition technique to improve our memory retention and recalling abilities.
But if the review schedule of Anki is not followed religiously, The cards start to leech and very soon there would be thousands of due cards.
This demotivates many Anki users and stops them from using Anki altogether.
