Light is a flashcard-based study tool powered by spaced repetition algorithms. You create flashcards with a question on the front and answer on the back. The intelligent algorithm calculates the optimal time to review each card based on your response ratings.

On the home screen, tap the "+" floating button. You can choose to create a Folder (ideal for organizing entire subjects) or a Deck (a set of flashcards for a specific topic).

When revealing the answer to a flashcard, choose one of the following:

• Again: The card will be reviewed again soon within the current session.
• Hard: The interval to the next review will be short.
• Good: The review interval will be moderate.
• Easy: The time interval to review this card will be significantly expanded.

To keep your studies engaging, Light includes achievements for study milestones (such as creating your first deck, rating cards, or maintaining daily study streaks). Unlocking achievements triggers an animated screen alert with sound effects!

The Premium plan removes all ads from the app and unlocks exclusive accessibility and Text-to-Speech study features, allowing the app to dictate the front and back of your flashcards aloud.

All subscriptions are managed directly by the official app stores (Google Play Store or Apple App Store). To cancel, open your store app, navigate to "Subscriptions" in your profile, and select Light to manage or cancel auto-renewal.

You can permanently delete your account by opening the Settings in your Profile tab and tapping the Delete Account option. All your progress data and private decks will be erased immediately from our cloud servers.
