What does ¿Cuánto cuesta? ask?
Personal, not permissive
Difficulty that meets you where you are.
Choose the subject and goal—not the easy way out. Latch is designed to infer your level from correctness and response time, independently for every topic and skill.
Subject-specific
Being strong in economics says nothing about your Japanese level. Progress stays tied to the skill.
Useful by repetition
Short retrieval reps turn otherwise forgettable impulses into practice that can compound.
