Why your daily reviews work
When a card feels easy, it shows up less often. When it feels hard, it returns sooner—so you strengthen weak spots before they fade. That's how short daily sessions turn into long-term recall.
Consistency you can see
Each session ends with a clear summary: what you strengthened, what moved up in mastery, and what's next—so the habit feels rewarding, not endless.
