Why spaced repetition actually works
The science behind spacing out your study sessions and why it helps you remember more with less effort.
Spaced repetition is one of the most effective learning techniques ever studied. Instead of cramming everything into one session, you review material at increasing intervals, just before you're about to forget it.
This approach leverages the "spacing effect," a phenomenon first described by Hermann Ebbinghaus in 1885. When you space out your learning, each review strengthens the memory trace, making it more durable over time.
CHILLO builds spaced repetition directly into every session. You don't need to plan when to review. The system handles it for you, adapting to your personal forgetting curve.
The result? You spend less time studying but remember more. It's not about working harder, it's about working smarter.
