Quobby uses a smart algorithm that shows you cards at optimal intervals. Cards you know well appear less frequently, while difficult cards appear more often to maximise learning efficiency.

Yes! Premium users can publish decks to the community. Go to a deck, tap the share icon, and choose 'Publish to Community'. Others can then download and learn from your deck.

You can manage your subscription in your iPhone's Settings app → Your Name → Subscriptions → Quobby. From there you can cancel or change your plan.

Premium users get automatic cloud sync. Your flashcards, habits, and progress are securely stored and synced across all your devices. Free users' data is stored locally on their device.

Yes! Premium users can sync flashcard decks, habits, scanned documents, and note metadata between iOS and Android. However, handwritten note drawings use platform-specific rendering engines (Apple Pencil on iOS, custom canvas on Android), so drawn content created on one platform will not appear on the other. Note templates, titles, folders, and text boxes will sync normally. We recommend using the same platform for note-taking and the other for reviewing your flashcards and habits.
