Memory science, study strategies, and product updates from the Flevro team.
An honest, feature-by-feature comparison of the best flashcard and spaced repetition apps in 2025 — including algorithm quality, pricing, mobile apps, AI features, and who each is best for.
A concrete, science-backed plan to build a vocabulary of 1,000 words in any language in 90 days — using spaced repetition, the right deck structure, and 15 minutes per day.
Cramming gets a bad reputation, but why exactly does it fail? We break down the cognitive science behind spaced repetition and show you what decades of memory research actually prove.
Anki is powerful but frustrating to use. We built Flevro to give serious learners the same science-backed spaced repetition — in a modern, cloud-native app with AI tools built in.
FSRS-5 is the most accurate spaced repetition algorithm available. Learn how it works, why it beats SM-2, and how Flevro uses it to cut your review time by 20%.
