Summary
A cross-platform notes app that organizes entries in a single list and supports access by AI agents through a Mac command-line interface.
About
Gravity Notes combines a chronological, append-and-review note workflow with local device storage and a command-line interface for AI agents and scripts. Its main strategic distinction is connecting personal notes to developer-oriented agent workflows.
Gravity Notes is a notes app based on an append-and-review workflow: notes are added to one list, with the newest entries at the top, while older notes move down and can be brought back with a swipe. It includes live Markdown, checklists, and full exports. On Mac, the Gravity CLI allows Claude Code, Codex, and user scripts to read and write notes. The app is available for iPhone, iPad, Mac, and Android. The product description states that users pay once and notes remain on their devices.

Portable note management
Use the app across iPhone, iPad, Mac, and Android, with full exports available for transferring or archiving notes.
Business Opportunities
Developer context management
Problem: Development notes and working context may be separated from AI coding workflows.
Solution: Use the Mac CLI to let Claude Code, Codex, or custom scripts access and update notes.
Estimated ROI: Potentially moderate through reduced context switching and easier reuse of notes; outcomes depend on how frequently users integrate notes into development work.
Execution: Adopt the CLI in individual or team workflows where notes are useful to coding agents, and use exports to support backup or migration processes.
Cross-device personal knowledge workflow
Problem: Users may need a simple way to capture and revisit notes across different device types.
Solution: Use the shared append-and-review model across the listed mobile and desktop platforms, with exports for portability.
Estimated ROI: Primarily individual productivity value, with returns dependent on consistent use and the relevance of captured notes.
Execution: Standardize personal capture in the single-list workflow and periodically export notes for archiving or use elsewhere.
