I’m building a cross-platform mobile app that helps users stay organized and in sync across iOS and Android. The core of the project is a productivity tool, so clean UX, quick load times, and rock-solid data handling matter as much as the code itself.
Key features I must see in the first release:
• Task management – users can create, edit, prioritise, and mark tasks complete.
• Calendar integration – events flow in and out of the native calendar APIs with two-way sync.
• User collaboration – real-time sharing of tasks and deadlines between team members.
I’m happy for you to work with React Native, Flutter, or another proven cross-platform framework; just outline your preferred stack and why you like it. Clean, well-commented code stored in a private Git repo is a must, and I’d like a TestFlight / Google Play internal test build at each milestone so I can review progress on real devices.
Acceptance criteria for hand-off:
1. All three feature sets function smoothly on current iOS and Android versions.
2. No critical bugs or crashes during a week-long beta.
3. Complete source code, README with setup steps, and build scripts included.
If you have shipped similar productivity or collaboration apps, please mention them—seeing thoughtful UI and polished interactions helps me decide quickly.
