I’m building a clean, no-frills productivity app whose sole focus is rock-solid task management. I want it running smoothly on both Android (Google Play) and iOS (App Store), with the same code-base where practical so maintenance stays simple. Key requirements • Core screens for creating, editing, organizing, and searching tasks • Local data persistence that syncs instantly when the device regains connectivity • Polished UI that follows Material guidelines on Android and Human Interface on iOS • End-to-end delivery: source code, compiled binaries, and store-ready builds—including signed APK/IPA files and the meta-data screenshots needed for each marketplace Right now I only need task management, but I’m open to layering in calendar integration or collaboration tools later, so please structure the project for easy expansion. If you have experience shipping dual-platform apps, handling App Store / Play Store submissions, and can guide me through provisioning profiles, keystores, and review checklists, let’s chat—my goal is to press “publish” with confidence.
