CAPTURE • From the app, from the Share button of any other app, or with Siri and Shortcuts ("Add an idea"). • Markdown formatting: headings, bold, italic, highlight, lists, quotes, code, links. • LaTeX equations, on their own line or in the middle of a sentence. • The place where the idea came to you, added automatically if you wish. FIND • Search by words, or by meaning: 1dea finds related ideas even when they share no word. • Coloured categories, tags and one-to-three-star ratings to filter in one tap. • Related ideas and links between notes to weave your thinking together. • A world map of your notes. REREAD • Home Screen widget: a random idea, from the categories you choose, refreshed anywhere from every 15 minutes to once a day. • "Random idea" in Siri and Shortcuts as well. • Project note: gather several ideas into one working draft.
