Slottica

Slottica is a vocabulary learning app that includes a dedicated Review mode designed to surface exclusively the cards that need the most attention, those sitting at knowledge levels 0 through 3, creating a focused study session without distractions from already-mastered material. In Review mode, Slottica filters your card deck automatically, hiding any card at level 4 or 5 and presenting only the ones that your swipe history or quiz answers have identified as still requiring reinforcement. No configuration needed, the filter applies instantly. This focused approach is especially valuable mid-learning-journey, when you've made progress through a deck but still have a cluster of persistent weak spots. Rather than reviewing the full deck and spending time on cards you already know, Review mode takes you straight to the gap. Review mode uses the same flip-and-swipe mechanics as regular study mode, so the interaction pattern is identical. The only difference is what cards appear, and that difference makes the time investment significantly more efficient. For learners with limited study time, Review mode is the most targeted option in Slottica: it ignores everything you've mastered and dedicates every card interaction to the words that most need your attention right now.
