I’m ready to move from concept to code on a brand-new productivity app and need a developer who can deliver a polished experience on both iOS and Android from day one. At its core, the app must let users create and track tasks, view and sync those tasks with their calendar, and collaborate seamlessly with teammates in real time. The flow should feel effortless: • quick task capture with priorities and due dates, • automatic calendar updates so schedules stay in sync, • shared workspaces where team members can comment, attach files, and see progress instantly. A clean, distraction-free interface is vital; think intuitive gestures, subtle animations, and fast load times even on older devices. Whether you prefer Swift + Kotlin, Flutter, or React Native, I’m open—as long as the final build is fully native-feeling, passes App Store and Play Store guidelines, and is easy to maintain. Deliverables I expect: 1. Wireframes and a clickable prototype for early feedback 2. The full production app for iOS and Android, source code included 3. Basic admin panel / backend hooks for user accounts, project data, and push notifications 4. Post-launch support for bug fixes during the first release cycle If you’ve shipped productivity tools before—especially anything with real-time collaboration or calendar syncing—let me see your work. I’m ready to start as soon as we agree on milestones and timelines.
