Spaced repetition is a scientifically-proven learning technique. Cadence uses the SM-2 algorithm to show you flashcards at optimal intervals. Cards you know well appear less frequently, while cards you struggle with appear more often. This maximizes retention while minimizing study time.

Yes! Premium subscribers can create custom flashcard decks. You can add cards manually or import from CSV files. Custom decks fully integrate with the spaced repetition system.

iCloud sync is a Premium feature. When you turn it on, your study progress and custom decks are backed up to your own private iCloud account so you can pick up on another device. Your data stays in your personal iCloud and is not shared with us.

Premium subscribers get access to the Apple Watch app. It syncs automatically with your iPhone. On your watch, you can do quick review sessions, check cards due, and track your streak. Perfect for studying on the go!

After revealing a card's answer, rate how well you knew it:

• Again: You did not know it, so the card will appear again soon
• Hard: You knew it with difficulty - shorter interval
• Good: You knew it well - normal interval
• Easy: You knew it instantly - longer interval

Be honest! Accurate ratings help the algorithm optimize your learning.
