The Simplest Spaced Repetition App for Busy Learners

Spaced repetition is the most effective learning technique science has ever discovered. So why don't more people use it? Because most spaced repetition apps are designed for power users. They assume you want to create flashcards, tweak scheduling algorithms, and manage complex deck hierarchies. For most people, that's way too much work.

The Simplicity Problem

Every spaced repetition app on the market (Anki, RemNote, SuperMemo, Mochi) revolves around flashcards. Creating good flashcards takes time and skill. Maintaining them takes discipline. And for many learning goals — remembering the key ideas from a book, retaining what you learned in a course, keeping professional knowledge fresh — individual flashcards are overkill. (For a detailed look at how the major tools compare, see our <a href='/blog/best-spaced-repetition-apps'>honest comparison of the best spaced repetition apps</a>.)

What if spaced repetition could be as simple as a todo list?

Spacey: Spaced Repetition as a Todo List

Spacey reimagines spaced repetition for regular people. Instead of flashcards, you work with topics. Instead of complex scheduling parameters, you pick a repetition plan. Instead of card reviews, you get todos. The entire workflow takes seconds: add what you learned, pick a plan, and check off reviews as they come up.

Who Is Spacey For?

• Book readers who want to remember what they've read
• Online course takers who want knowledge to stick
• Professionals maintaining certifications or technical knowledge
• Students supplementing their existing study methods
• Self-learners exploring new fields and topics
• Anyone who tried Anki and found it too complex

Key Features

• Add any topic in seconds — no flashcard creation required
• Choose from proven repetition plans or create custom schedules

The best tool is the one you actually use. By making spaced repetition radically simple, Spacey removes the barriers that stop most people from sticking with it.
