THE SCIENCE BEHIND OIVALLA
Learners using active recall retain 93% of information vs. 79% for passive study. Bite-sized sessions improve retention by 50% compared to traditional formats. Personalized instruction leads to dramatically better outcomes across 76 peer-reviewed studies.

Oivalla combines spaced progression, retrieval practice, and adaptive difficulty — the three most validated techniques in learning science — into an experience that feels effortless.
