Description
Spaced is a simple, effective vocabulary trainer built around spaced repetition. Review words at the right moment—before you forget them—and build long-term memory with just a few minutes a day.
Originally created to help our daughters learn simplified Chinese characters (hanzi), Spaced has grown into a flexible tool for anyone learning vocabulary, phrases, symbols, or other small bits of knowledge.
WHY SPACED
Spaced began as a physical Leitner box full of flashcards—useful, but not portable. We turned that idea into an app that is smart, lightweight, and easy to use every day.
HOW IT WORKS
Spaced follows the forgetting curve: review information at increasing intervals to retain it longer.
• Create a WordList for what you want to learn
• Study briefly each day
• Remembered words advance to higher levels
• Forgotten words return to the start
The app schedules everything automatically using a 56-day cycle.
CREATE YOUR WORDLISTS
Make a WordList with a title, start date, and weekly test day. Add words manually or choose from built-in Simplified Chinese lists. Each item supports notes, examples, and optional hints.
STUDY
Tap Start to begin a session. If you take a break, Spaced picks up right where you left off. The Home screen shows the next level scheduled for review.
STARRED WORDS
Mark tricky words for extra practice. Filter by all starred words, specific star levels, or a weighted mode that shows higher-star words more often.
REVISION AND TESTING
Spaced includes two study modes:
• Revision (Levels 1–2): Build familiarity with new or recent words.
• Test (Levels 3–7): Check what you know. Correct answers advance; incorrect ones return for reinforcement.
External keyboard controls are supported in both modes.
ICLOUD SYNC
Your learning stays up to date everywhere. Spaced uses iCloud and CloudKit to automatically sync your WordLists, progress, and starred words across all your devices.
STAY CONSISTENT
A few minutes a day can make a big difference. Keep going, trust the process, and watch your vocabulary—and confidence—grow.
Happy studying with Spaced.
