The rules (read this first)

1. Each card is tracked separately. Every card has its own score from 0 to 21. The ring under the question shows progress for this card only.
2. Each I Know = +1 point on that card. Tap I Know when you remembered the answer. The ring fills a little more.
3. 14 points = Mastered. Tap I Know 14 times on the same card (not 14 different cards) and that card is mastered.
4. 21 points = Expert. Keep going on the same card until 21 I Know taps — that is the highest level.
5. This Week & This Month count mastered cards — not every tap. Your goal bar moves +1 only when a card reaches 14 points (mastered) or you tap Already know. Example: 10 I Know taps on 10 different cards adds to your total Points, but This Week stays the same until you master at least one card.
6. Why isn't my bar moving? You are earning points on the ring, but the weekly/monthly bar waits until you finish a card (14 points or Already know).

Your goal: 0 / week and 0 / month means master that many cards — not that many random taps.
