Rate your recall with four options — Again, Hard, Good, or Easy — and the system schedules reviews accordingly.

• Optimized recall — the algorithm shows cards right before you'd forget them.

• Long-term retention — designed for languages, medical terms, and deep learning.

Tracks the exact time between displaying the question and revealing the answer. Combines stopwatch feedback with classic binary grading.

• Recall speed analytics — know not just if you remember, but how fast you recall.

• Stopwatch display — real-time tracking promotes focused, active study habits.

• Performance metrics — records exact response time in seconds for review session history.
