The Feynman technique + flashcards: how to combine them for faster understanding
The Feynman technique exposes the gaps in what you actually understand. Flashcards lock the patched explanations into long-term memory. Here is the four-step method, why it works, and a concrete workflow for turning Feynman sessions into spaced-repetition decks.
What is active recall? A science-backed explanation
Active recall is the practice of retrieving information from memory rather than rereading it. Studies show it produces 50–80% better retention than passive review. Here is what the research says and how to apply it.
Anki vs Memor More: an honest comparison for Apple users in 2026
Anki is free, powerful, and cross-platform. Memor More is local-first, native on iPhone and Mac, and built around a modern FSRS algorithm. Here is when each app is the right choice — and when they are not.
Best spaced-repetition apps in 2026 — honest comparison
Anki, Quizlet, Brainscape, RemNote, and Memor More compared head-to-head. Algorithm, price, platform, and who each app actually suits.
Spaced repetition vs massed practice: which one actually works?
Spaced repetition beats massed practice (cramming) for long-term retention by effect sizes of d = 0.46 to g = 1.15. Cramming wins only on tests taken within hours. Here is what the research says — and when each method is the right tool.
Share Your Flashcard Decks — Public Sharing Is Coming Soon
The next Flash Memory release will enable public deck sharing for all users. Until then, you can already share flashcard decks with friends or students via a sharing code, with automatic updates synced from the author.
Spaced repetition works — what 130+ years of research shows
Spaced repetition is the most well-proven study technique in cognitive science, with effect sizes from d = 0.46 to g = 1.15. It beats massed practice (cramming) for long-term retention in almost every domain tested. But it has real limits — it shrinks for complex tasks, disappears on same-day tests, and only works if the spacing interval matches your actual retention goal. Here's what 50+ studies, meta-analyses, and RCTs actually say.
