Hacker Notes brings a bold, terminal-inspired aesthetic to your everyday note-taking. Designed for developers, tech enthusiasts, and anyone who prefers a clean, dark workspace β€” it combines powerful editing tools with a visual style straight out of the command line. RICH TEXT EDITING Write and format your notes with full rich text support β€” headings, bold, italic, underline, strikethrough, ordered and unordered lists, checkboxes, code blocks, blockquotes, and inline links. Everything you need to capture thoughts, tasks, or technical notes. HACKER TERMINAL AESTHETIC The app's signature neon-on-black look is fully customizable. Choose from 12 preset accent colors β€” green, cyan, magenta, amber, teal, purple, and more β€” or dial in your exact shade using the HSL color sliders. Every screen, button, and dialog reflects your chosen color. ORGANIZE WITH TAGS Attach multiple tags to any note and filter your collection instantly. Combine tag filtering with real-time search across titles and content to find exactly what you need. EXPORT & SHARE Long-press any note to export it as a formatted PDF or share it as plain text. Great for sending quick summaries or keeping formatted copies of your notes. PRIVACY BY DESIGN All notes are stored locally on your device using an embedded database β€” no account required, no cloud sync, no data sent anywhere. Your notes stay yours. GRID & LIST VIEWS Switch between a compact list layout and a spacious grid view to browse your notes the way that works best for you. SORT YOUR WAY Sort notes by creation date or last modified date, in ascending or descending order, so your most relevant notes are always at the top. LIGHTWEIGHT & FAST No background syncing, no bloat. Notes open and save instantly because everything lives on your device. Whether you use it for daily journaling, coding notes, task lists, or just keeping track of ideas β€” Hacker Notes gives you a tool that looks as sharp as the work you do in it. -------------------------- Disclaimer Hacker Notes stores all content locally on your device.
