How do flashcards decide what to show me?
Every setup is a deck. Grade each card Again, Hard, Good or Easy and the card is scheduled back: an Again comes back in minutes, an Easy in weeks, stretching further each time you get it right. That's spaced repetition. The point is to show you a card right before you'd forget it, not on a fixed day.
Nothing due?
That's good. Come back tomorrow, or open a specific setup deck to add its cards to your schedule.
A card you know keeps coming back
Grade it Easy, not Good. Good means "I got it, keep checking". Easy means "stop showing me this for a while".
Weak cards
Weak cards collects everything you've been missing across every deck into one drill. It's the fastest way to fix the instruments that keep tripping you up.
Streaks and the heatmap
Your streak, accuracy trend and heatmap are on Dashboard → Study. A day counts if you review at least one card, on the website or in the app; they share one history.
