The Science
Gets More Precise as You Learn
Your Evolving Algorithm
Ebbinghaus Forgetting Curve
Without intervention, you forget ~80% of new information within 30 days. This isn't a flaw — it's how human memory works. The key is knowing exactly when to review.
FSRS: Free Spaced Repetition Scheduler
A peer-reviewed algorithm that calculates optimal review timing for each individual word. Tracks stability, difficulty, and retrievability — then schedules reviews right before you forget.
Self-Evolving Engine
Three independent FSRS instances: Global scheduling, Receptive (listening/reading), and Productive (speaking/writing). Each adapts to your individual performance pattern.

Daywika uses a proprietary AI algorithm built on cognitive science research. It individually tracks each word's stability, difficulty, and retrievability — scheduling reviews right before you forget. The more you use it, the more it adapts to your personal memory patterns, becoming increasingly optimized for you over time.
Currently, 3 languages are available for learning, with new languages being added at a rapid pace. Our AI algorithm works universally across any language, so expansion is fast. Both learning target languages and UI languages are diverse and growing.
Most language apps rely on gamification — streaks, XP, characters — to keep you engaged. Daywika takes a fundamentally different, data-driven approach: a proprietary AI algorithm, cognitive asset management, and constructive motivation through real metrics. Less decoration, more actual retention results.
Yes. Your learning data is encrypted and stored securely. We don't sell personal data to third parties. Check our Privacy Policy for full details on data handling and your rights.
Core review functionality works offline — your daily review queue is available without internet. Syncing, AI dashboard, and some analytics features require a connection.
