I’m planning to build a mobile productivity tool focused solely on task management and to release it simultaneously on iOS and Android. The first milestone is a clean, intuitive interface that lets users create, prioritise, and track tasks, with push-notification reminders and offline access that syncs when a connection returns. Calendar integration and broader collaboration tools can wait for later versions; right now I want a rock-solid core experience. End-to-end delivery is essential. That means UX research, wireframes, polished UI that follows each platform’s design language, the complete codebase (Swift/Kotlin or a high-quality framework such as Flutter or React Native), an API layer if you decide server sync is best, and fully tested release builds ready for the App Store and Google Play. Deliverables • Approved wireframes and final UI designs • Well-documented source code and project files • Tested, release-ready iOS and Android builds • README with clear setup, build, and deployment steps Acceptance criteria: smooth task CRUD operations, background and offline functionality with reliable sync, timely push reminders, and zero critical bugs in QA. Share your preferred tech stack, indicative timeline, and any prior examples that prove you can hit these marks.

Hi there, I have read your project requirement. You need an end-to-end mobile task management app for iOS and Android with a clean and intuitive interface, offline functionality with reliable sync, push notifications, and fully tested, release-ready builds along with complete design and documentation. We can deliver a scalable, high-performance app using a single codebase approach with strong focus on UX, offline-first architecture, and smooth performance. A few quick questions: ================== Do you prefer Flutter (single codebase) or native development (Swift/Kotlin)? Should the app support user accounts and cloud sync from version 1? Any reference apps or design styles you want us to follow? Do you plan to add collaboration or web dashboard in future phases? Best Regards, Srashtasoft Team

Hello, You're absolutely right to focus on a rock-solid core first. Building a task management app with reliable offline sync and push reminders requires careful architecture, and that's exactly where I specialize. I recommend building this using Flutter with an offline-first approach: • Local database (SQLite/Hive) for offline access • Background sync when connection returns • Push notification reminders • Clean, intuitive task management UI • iOS and Android simultaneous release I will handle end-to-end delivery including: • UX research & wireframes • Polished platform-friendly UI • Full source code & documentation • API layer (if multi-device sync is required) • Tested, release-ready App Store & Play Store builds I’ve built productivity and offline-first apps with push notifications and reliable sync, focusing on performance, stability, and clean UX. Timeline and tech stack can be finalized after discussing scope and priorities. I’d be happy to share relevant examples and discuss the architecture approach. Looking forward to collaborating. Regards Abhishek

I have read your job post and understand you need a mobile task management app for iOS and Android with offline support, sync, and push notifications. I am a mobile developer with experience in React Native and Flutter, and I have built apps with task systems, local storage, and API syncing before. My approach is simple. First, I will design clean wireframes and a simple UI for task creation, priority, and tracking. Then I will build the core app with offline support so users can add and update tasks even without internet. After that, I will add sync when connection returns and set up push notifications for reminders. Finally, I will test everything and prepare release-ready builds for both App Store and Google Play with clear documentation. I will make sure the app is fast, simple, and stable with no critical bugs.
