The Problem
Most people review cards on a fixed schedule or whenever they feel like it. Both approaches waste time on things you already know while important knowledge slips through the gaps.
The Solution
Studara implements the SM-2 algorithm, proven across decades of memory research. After reviewing each card, you rate it 1 to 4. The algorithm calculates the precise interval before your next review — tomorrow, next week, or next month. Difficult cards appear more often. Easy cards appear less.
