Project description:
"I need a developer who can build a polished productivity app that runs smoothly on both iOS and Android from a single codebase.

I’m happy for you to suggest the most efficient framework—Flutter, React Native, or another option you trust—so long as it delivers native-level performance and maintainability. You’ll handle everything from setting up the project structure and designing the database through to testing and preparing release builds for the App Store and Google Play.

Deliverables
• Full source code with clear inline comments
• Two ready-to-submit builds (iOS & Android)
• Brief setup/maintenance documentation
• Hand-off meeting or recorded walkthrough covering any final questions

Acceptance criteria
• Task creation, editing, and completion flow works without crashes on current iOS and Android versions
• Real-time time tracking runs accurately in the background and survives app restarts
• Data persists locally and syncs to cloud storage when a connection is available
• Interface follows platform guidelines and passes review-ready accessibility checks

If all of this aligns with your skill set, let’s discuss timeline and milestones so we can get the first version into users’ hands quickly." (client-provided description)
