Ideon is a private, scrollable feed for the ideas, links, files, concepts, terminology, and insights you want to keep. Capture an idea manually with text, photos, video, audio, or file attachments. Share links and supported files from other apps into Ideon, then keep everything in a simple personal feed you can revisit later. Ideon is built for the small pieces of knowledge that are too useful to lose: AI answers, articles, places, documents, diagrams, study notes, and real-life observations. Add related notes to older posts, connect follow-up thoughts, and let Ideon gently bring useful ideas back when they may be worth revisiting. There are no decks to organize, sessions to complete, or study streaks to protect. Pull to reshuffle, keep scrolling, search your library, and mark ideas as useful, fragile, or mastered to influence when they return. Features: • A private feed for ideas, links, files, and notes • Share links and supported files from other apps • Manual posts with text, camera, photos, video, audio, and file attachments • Related notes and comments for follow-up thinking • Searchable concept library • Gentle optional reminders for older saved ideas • Subtle spaced-repetition weighting without flashcards • Local storage for manually captured content • No advertising or cross-app tracking Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://www.ideonapp.app/privacy/
