Read full description

iFlow note is a note-taking app based on Niklas Luhmann's Zettelkasten method. It uses three types of cards to help you separately capture inspirations, literature excerpts, and permanent knowledge, while intelligently linking them in the background. Don't worry about building a "perfect system" from day one. Just start by recording that one thought you have now. Organizing, connecting, and writing will naturally become easier later. Who is it for: Creative professionals who often get fleeting ideas: creators, product managers, engineers, indie developers. Students and researchers who want to systematically organize their reading notes and paper insights. Anyone looking to build a personal knowledge base and accumulate material for writing. The three note types allow for clear distinction at a glance: Inspiration Cards: For capturing fleeting thoughts, one-liners, and voice snippets. Supports voice recording, which can be transcribed to text later for review. Literature Cards: For excerpts from books, articles, or web pages, plus your own brief understanding. Supports text extraction and photo capture (keeping original screenshots). Permanent Cards: For rewriting ideas and conclusions in your own words to form reusable knowledge cards. Supports Markdown, ideal for longer content, article outlines, and drafts. Quick Capture: Create Spark, Literature, or Permanent cards directly from the bottom menu on the home screen. Multiple input methods (text, voice, image) prioritize ease-of-use in the moment. Tagging & Search: Use tags to categorize cards by theme, project, or context. Search across titles, content, and tags to quickly rediscover past ideas. Card Linking: Build a knowledge network by linking related Spark, Literature, and Permanent cards. View "Linked Cards" in the detail page to navigate your knowledge web naturally. Review & Reminders: Set review deadlines for Spark and Literature cards to avoid forgetting them. Receive reminders to periodically review cards and upgrade them to Permanent Cards. Schedule spaced repetition reviews for Permanent Cards to reinforce understanding. Trash & Archive: Restore accidentally deleted cards from Trash. Archive infrequently used but valuable cards to reduce clutter. PRO Benefits (Unlocked via Subscription): The free version is sufficient to get started. PRO offers more capacity for power users: Unlimited notes. Record multiple audio segments per Voice Card. Attach multiple images per Image Card. iCloud Sync & Backup: Keep data consistent across devices, with export option for Permanent Cards as Markdown files. (Specific prices and terms are as displayed within the app. Subscription can be canceled at any time.) Privacy & Data: Local-first by default: Your data is stored on your device and your personal iCloud. Minimal data collection: We do not collect unnecessary personal information or engage in excessive tracking. Detailed Terms of Service and Privacy Policy can be viewed in the app's settings page.
