Best spaced repetition app for 2025: 7 top picks

You forget 70% of what you learn within 24 hours.

This isn't a personal failing. It's how memory works. Hermann Ebbinghaus discovered this "forgetting curve" in 1885, and it still defines how information slips away unless you intervene.

Spaced repetition schedules reviews at increasing intervals that follow your brain's forgetting curve. Each timed review refreshes a memory trace, slowing decay and strengthening recall. This active retrieval separates fleeting familiarity from durable knowledge.

But not all spaced repetition apps serve the same purpose. Some excel at memorizing facts for exams. Others help you retain what you read. A few focus on keeping your own notes and ideas alive.

Choosing the wrong tool means wasting time on features you don't need or missing the ones you do.

The spaced repetition revolution: why your brain needs it in 2025

Spaced repetition schedules reviews at increasing intervals that follow the brain’s forgetting curve. Each timed review refreshes a memory trace, slowing decay and strengthening recall. Instead of passively re-reading, you actively retrieve information. This active retrieval separates fleeting familiarity from durable knowledge.

In practice, spaced repetition works like this:

• Algorithms, such as those in Anki, adjust intervals based on how easily you recalled an item.
• Marking an item as “hard” schedules it for review soon.
• Marking it “easy” delays the next review.
• The system focuses on active recall, reinforcing neural connections in areas like language vocabulary, medical terms, or notes from your personal knowledge base.

What makes a great spaced repetition app in 2025

Active recall vs. passive review

Spaced repetition tools use different methods to help you retain information.

Some tools use classic flashcards, such as Anki, Quizlet, and Memrise. These force you to actively recall answers and then schedule the next review based on how well you remembered the content. This approach works best for precise, repeatable tasks like medical facts, vocabulary, and formulas.

Other tools focus on capturing highlights and resurfacing them on a schedule. They provide gentle reminders instead of testing, which suits readers who want to retain insights without memorizing exact wording.

Each model aims for a different outcome: exact recall, long-term idea exposure, or continuous engagement with your own work. Choose the one that fits what you need to remember and apply.

AI-powered scheduling and personalization

Modern spaced repetition systems build on memory science concepts like intervals and forgetting curves. They add layers of personalization to improve effectiveness.

For example, FSRS, used in Anki, analyzes your recall history and uses probability models to predict when you will forget. It then adjusts the review intervals accordingly.

Tools like Anchrs and Recall automate card creation from your source material. They fill in translations, pronunciations, or images where useful, saving you time.

Systems focused on personal notes, such as Daily Brain Bits, use AI to generate dynamic quizzes, suggest conceptual links, and let you prioritize areas to revisit.

The key is adaptation: your review schedule should evolve with your performance, habits, and current priorities instead of staying fixed.

Cross-platform sync and offline capabilities

A useful spaced repetition app works wherever you do.

True cross-device sync ensures seamless sessions across desktop, mobile, and web platforms. AnkiWeb is a popular example of this.

Offline-first apps like Mochi and Screvi let you review even without Wi-Fi. This ensures constant access.

Progressive Web Apps (PWAs) like Anchrs avoid installation friction and run across browsers and devices.

Integration with note platforms, such as Daily Brain Bits connecting to Notion and Obsidian, allows your spaced-review system to live alongside your knowledge base.

A practical criterion: choose a tool that follows you across devices and keeps your content accessible when needed.

Content creation friction: the make-or-break factor

The effort needed to create and maintain review items determines whether you keep using an SRS or abandon it.

Legacy tools often suffer because manual card creation and tagging take too much time. Many users start strong but stop quickly. Complex setup processes contribute to abandonment as well.

Newer tools reduce friction by automating content creation. Recall and Anchrs turn source materials into review items with minimal input.

Read-capture services like Screvi send highlights straight into your review feed.

Personal-note systems such as Daily Brain Bits pull directly from your notes to surface quizzes or suggestions without requiring manual tagging.

When choosing an app, look for:

• Low effort to create review items
• Intelligent automation that respects your original context
• Fast, frictionless review flow that integrates smoothly into your workflow

These qualities separate tools people actually use from those that collect dust.

1. Daily Brain Bits: the knowledge worker's missing link

Why your personal notes deserve spaced repetition too

As your Notion or Obsidian archive grows, individual notes often get less attention. Important connections between ideas tend to fade.

Traditional spaced repetition systems focus on memorizing external facts like vocabulary or exam answers. They are not designed to maintain your own evolving thinking.

Daily Brain Bits (DBB) fills this gap by resurfacing the notes you wrote, not just highlights from others. This keeps your original research, syntheses, and brainstorms accessible and useful. The goal is not rote memorization, but maintaining context, relevance, and creative momentum.

How Daily Brain Bits solves the knowledge worker's paradox

Learning apps like Anki, Quizlet, and Memrise excel at structured recall. But they do not fit well with the messy, changing material knowledge workers produce.

Reading-capture tools like Readwise push external authors’ ideas back to you. This helps with exposure but does not revive your own thinking.

DBB combines these approaches. It:

• Automatically resurfaces whole notes in context, no flashcard creation needed.
• Helps you revisit and synthesize past work, turning your archive into a working toolkit.
• Keeps your notes actionable so old research can support current projects.

This approach reconnects you with your existing ideas and helps them evolve, rather than simply memorizing facts.

The 4 Rs framework: resurfacing, reconnecting, refreshing, remixing

DBB’s workflow focuses on four key actions:

• Resurfacing: Brings dormant notes back when they are most useful.
• Reconnecting: Encourages links between different ideas to spark new insights.
• Refreshing: Helps you to update or correct outdated information.
• Remixing: Uses resurfaced material as input for new projects, outlines, or frameworks.

Unlike isolated flashcards, DBB preserves context so a paragraph from a year-old note can inspire solutions for today’s problems.

Notion and Obsidian integration: making your second brain come alive

DBB connects to the two main places people store long-form thinking: Notion and Obsidian. It works with any tool stack, avoiding ecosystem lock-in.

Whole notes become eligible for resurfacing automatically—no manual tagging or card formatting needed.

This turns your second brain into an active resource instead of a passive archive.

Email delivery and LLM-powered quizzes

Daily Brain Bits sends resurfaced notes directly to your inbox at a schedule you set. This removes the need to open another app.

On top of that, DBB uses large language models to generate short quizzes from your notes. These can be multiple choice or cloze-style prompts that hide key concepts and encourage recall.

You can prioritize or deprioritize items and accept suggested links between notes, making resurfacing targeted instead of random.

The result is that you don’t just re-read your notes—you test, challenge, and refine them.

Pricing and who it's for

DBB offers a free and $10 pro plan with AI features and more customization options.

It suits people who rely heavily on their own notes:

• Researchers managing multiple hypotheses
• Product managers tracking lessons from past launches
• Writers reusing brainstorms and drafts
• Consultants recalling proprietary frameworks quickly

No complex setup or manual flashcard creation, just a steady pulse that keeps your second brain active and useful.

2. Anki: the power user's memorization engine

Feature overview and FSRS algorithm

Anki adapts to your learning needs. This open-source flashcard platform uses FSRS (Free Spaced Repetition Scheduler), an algorithm that analyzes your card history. It predicts when you might forget information and adjusts review intervals for each card accordingly.

The three categories of spaced repetition: which one do you need?

Category 1: Learning-focused apps for memorizing facts

These apps drill concrete facts until they stick. You create or download decks of bite-sized Q&A cards and practice active recall. Each card becomes a deliberate learning unit.

This workflow suits vocabulary, anatomy, formulas, and certification prep—situations where precise recall matters.

Trade-offs include:

• High effectiveness for fixed facts, but high setup cost due to deck-building and maintenance.
• Designed for “student mode,” requiring intentional effort and repeated practice.
• Not suitable if you want to evolve personal ideas rather than memorize external material.

Use these apps when you need mastery of external knowledge and accept the effort that comes with deliberate practice.

Category 2: Reading retention apps for consumed content

These tools automate review of what you consume. Highlights from Kindle, articles, newsletters, and web clippings return to you on a schedule. They reduce effort by removing the need to create cards manually.

They work well for preserving quotes, frameworks, and insights from other authors. These apps offer:

• Low friction, as highlights resurface automatically.
• Support for professional development, research, and retaining reading takeaways.

Limitations include:

• Focus on other people’s content, not your notes or drafts.
• Not suitable if you want to iterate on personal ideas or maintain your own thinking.

Category 3: Personal knowledge reinforcement for your own notes

This category targets the notes you write yourself. As archives grow, valuable ideas fade. These systems resurface whole notes with context intact, so your past thinking feeds current work.

Instead of breaking ideas into flashcards, they emphasize maintenance, connection, and synthesis. They:

• Keep your personal research, drafts, and project ideas accessible.
• Encourage revisiting, updating, and remixing notes instead of rote memorization.
• Suit anyone building a “second brain” who wants past work to stay actionable.

This category is ideal for researchers, writers, consultants, product managers, and knowledge workers focusing on connecting and applying their insights.
