@vipinjain1213

Hi, I’d build this as a clean, focused app where tasks, calendar sync, and reminders stay tightly connected without adding extra complexity. For Android, Kotlin with a simple layered structure will keep things easy to maintain. Tasks will be stored locally using Room, so everything works fast even without internet, and the data layer can be extended later if you connect it to an API. Calendar sync will use the device’s native calendar provider, so tasks show up alongside existing events without duplication. Updates should reflect both ways, keeping things consistent. Reminders will be handled with WorkManager or AlarmManager so notifications trigger reliably and respect Do Not Disturb settings. The idea is that alerts feel helpful, not intrusive. UI will follow Material 3 with a clean layout so users can add and manage tasks quickly without extra steps. Do you want recurring tasks and reminders in the first version, or keep it limited to one-time tasks for now?

@abhishek060

Hi, Your app isn’t just a simple to-do list — it requires reliable task management, real calendar sync, and stable background notifications, which is where most productivity apps fail. I’ve built Android apps using Room, Work Manager, and clean MVVM architecture, and I can deliver a stable, scalable MVP that meets your acceptance criteria. How I’ll Build It • Task Management — Create, edit, prioritise, complete tasks (Room database) • Two-Way Calendar Sync — Native Android Calendar Provider integration • Smart Notifications — Work Manager / Alarm Manager respecting Do-Not-Disturb • Material 3 UI — Clean, fast, and friction-free experience • Future-Ready Architecture — MVVM + Repository pattern for API expansion Deliverables ✔ Buildable Source Code ✔ Signed APK (Android 10+) ✔ Clean Documentation + README ✔ Stable performance (No crashes / ANRs) Quick Questions Should tasks sync to user's default calendar or app-specific calendar? Do you want multiple reminders per task? Should completed tasks remain in calendar or auto-remove? I can start immediately and deliver the first working build within timeline. Looking forward to building your productivity app. Regards, Abhishek

@Linkmez

Hi, I can build this Android productivity app in Kotlin with clean architecture, Material 3 UI, and a local data layer that is ready for future API integration. Your MVP is well defined: task management, two-way calendar sync, and reminder notifications that respect Android system rules including Do-Not-Disturb. I would build this in Android Studio using Room/DataStore, modular architecture, and Android best practices to keep the app stable on Android 10+. My approach: 1. Build task flows for create, edit, prioritize, complete. 2. Integrate native calendar sync so due dates appear alongside existing events. 3. Add scheduled reminders with reliable notification handling. 4. Deliver complete source code, signed APK, and a concise README for setup, architecture, and future extension. I focus on production-ready mobile work: clean code, maintainable structure, and a proper handoff instead of a rushed demo. Proposed Timeline: - App foundation + UI: 1-2 days - Task management: 2 days - Calendar sync + reminders: 2-3 days - QA, APK signing, README: 1 day One question: should changes made directly in the device calendar also update tasks in the app, or is app-to-calendar sync enough for v1? Best regards,

@RajAbhisek

Hello, Kotlin with MVVM clean architecture in Android Studio. Room for local persistence with a repository pattern abstracting the data layer — swapping in a remote API later requires touching exactly one file. Task management built on a flexible data model: title, description, priority level, due date, completion state and tags. Full create/edit/delete with priority-based sorting and filtering. Material 3 throughout — dynamic colour theming, proper touch targets, accessible contrast ratios. Calendar integration uses the Android CalendarContract provider for genuine two-way sync — tasks with due dates appear as native calendar events, and changes in either direction stay consistent. No read-only workarounds. Reminders built on WorkManager with AlarmManager for time-critical notifications. Do-Not-Disturb rules respected via NotificationManager channels — users set priority per task, system DND policy honoured automatically. No phantom notifications, no missed alerts after device restart. Architecture is layered cleanly: UI → ViewModel → Repository → local Room database. Adding a remote data source means implementing one interface, nothing more. Deliverables: full documented source, signed APK targeting Android 10+, README covering setup, architecture decisions and data layer extension guide. Shall we align on your Material 3 colour scheme before I start? Regards, Raj

Hi, This is a clean and well-defined app, I like the focused scope. I’ve built similar structured applications where the priority is reliability, clean architecture, and smooth user flow rather than overcomplicated design. I can implement task management with proper local storage, integrate with the device calendar, and ensure reminders trigger correctly while respecting system settings. Everything will be organised in a way that’s easy to extend later if you move to a backend. I focus on making apps stable, simple, and easy to maintain, not just “working once”. I can start immediately and deliver a solid first version quickly ?
