I need a straightforward productivity app that runs natively on both iOS and Android. Its single-minded focus is Inventory: a clean interface for adding, viewing, and updating stock items quickly from a phone or tablet. Core scope • Build two fully functioning installations—one for the App Store and one for Google Play—using a common codebase (React Native, Flutter, or a framework you prefer). • Implement the Inventory feature end-to-end: item creation, quantity edits, basic search, and simple reporting. • Keep the architecture open so I can later layer in other productivity options such as task management, calendar integration, or note-taking without a full rewrite. What I will provide • Wireframes outlining the main screens. • A lightweight brand style guide (colors, logo, fonts). • API endpoints for syncing inventory data with our back-office system. What I expect back • Source code with clear comments. • Two signed builds ready for submission, plus instruction notes for future updates. • A brief hand-off video or call walking me through the project structure and build process. If you have recent experience shipping inventory or productivity apps on both stores, I’d love to see those links. Let’s keep this as lean as possible so we can move from concept to store release quickly.
