Learning system
Vocabulary practice that adapts to the learner
Clingword uses learner performance to decide when to introduce new vocabulary and when previously learned words should return for review.
Its review schedule follows the forgetting curve, turning reinforcement-learning signals into a more individualized study plan.

The product reached more than 20,000 users in under two months. I worked across the reinforcement-learning logic, front-end experience, and product development.
