Gravity is a fast, private notes app with one stream, instant capture, and a simple rule: swipe to bump what matters back to the top. You open your notes app to jot down a quick idea. But first: which folder? What tags? Should you link it to something? By the time you've decided, the thought is gone. Gravity eliminates every barrier between your thoughts and the page. No folders. No tags. No complex systems to maintain. Just one continuous stream, and your attention decides what stays relevant. - Syncs privately via your personal iCloud account. No third-party servers. - No account required. No sign-up. No tracking. - One-time purchase. No subscription. No ads. HOW IT WORKS Append — Open the app and start typing. Your note saves automatically. No tapping "new note." No choosing a location. Just capture Review — Scroll through your stream. New notes live at the top. Older notes naturally drift down over time, like thoughts settling in your mind. Rescue — When something catches your attention, swipe right to bump it back to the top. Your attention becomes your organization system. Archive — When a note has served its purpose, swipe left. Done. FEATURES Quick Capture - Start typing the moment you open the app - Auto-save means you never lose a thought - Hit return twice to save and start fresh The Stream - One continuous timeline of all your notes - No folders, categories, or nested hierarchies - Scroll to review; swipe to act Bump to Top - Swipe right on any note to rescue it - Your attention naturally sorts what matters - No manual organization required Lightweight Prefixes - Type todo: or idea: or any prefix at the start of any note - Search by prefix to create instant filtered views - Color-coded highlighting makes prefixes pop Fast Search - Find notes instantly across thousands of entries - Partial-word matching catches what you're looking for - Built on a high-performance local database Quick Actions - Swipe left to reveal: archive, delete, share, copy - Every action is one gesture away - Undo protection for destructive actions Import and Export - Export all your notes anytime to a single json file - Import with validation and duplicate protection - Your data, your control DESIGNED FOR FOCUS - Warm, paper-like aesthetic - Satisfying haptics on every interaction - Fluid gestures that feel natural - Minimal setup - Nothing to learn WHO GRAVITY IS FOR Designed for plain-text note taking, quick ideas, and lightweight to-dos.

Not a knowledge graph. Just your thoughts, in one stream. INSPIRED BY SIMPLICITY Gravity is built around Andrej Karpathy's append-and-review method for personal notes: keep one running stream, review it periodically, and let your attention decide what stays relevant. Most notes apps tolerate this workflow. Gravity is designed for it. ONE PRICE. YOURS FOREVER. Pay once. No subscription. No in-app purchases. No ads. Just a thoughtfully crafted notes app that respects your attention and your wallet. Stop organizing. Start thinking. Download Gravity and let your thoughts sink in.
