Cross-Platform Productivity App

I need a seasoned mobile developer to turn my concept for a productivity app into polished, store-ready builds for both iOS and Android. The goal is a straightforward, reliable tool that helps users organise their day without unnecessary clutter.

You’ll guide the project from initial architecture through final submission, covering:
• Selecting an appropriate cross-platform stack (React Native, Flutter, or a similar framework that guarantees native-level performance).
• Crafting a clean, intuitive UI that feels perfectly at home on both operating systems.
• Implementing core productivity features (think task capture, quick editing, reminders, and cloud sync).
• Integrating standard analytics and crash-reporting so we can iterate intelligently after launch.
• Packaging, testing, and complying with App Store and Google Play requirements until approval.

Deliverables
1. Full source code in a private Git repo with clear commit history.
2. Test builds throughout development plus a signed release build for each platform.
3. Brief technical documentation: setup instructions, architecture overview, and a short hand-off video call to walk me through the codebase.

Acceptance Criteria
• Both versions pass platform-specific review and are live in their respective stores.
• No critical or high-priority issues in the crash logs during the first week of release.
• UI behaves consistently across common screen sizes (phones and tablets).

If you have a track record of shipping responsive, cross-platform productivity tools and can start soon, let’s talk.
