I’m looking to have a fully-featured productivity app built from the ground up for both iOS and Android. The core idea is to give users a streamlined hub that helps them stay organised and efficient throughout the day. Although I have a clear vision for the overall experience, I’d like your input on the exact feature mix. Task management, calendar integration, and even lightweight time-tracking are all on the table, but I’m open to hearing how you would prioritise or enhance these functions for maximum impact and usability. You’ll be responsible for: • Designing an intuitive, modern UI that feels native on both platforms • Developing the complete iOS and Android • Implementing a robust, scalable backend (Firebase, Supabase, or your recommended stack) for user accounts and data sync • Setting up push notifications and in-app reminders • Ensuring smooth data sync across devices and secure user authentication Deliverables include: 1. Source code for iOS and Android, fully documented 2. Working builds ready for App Store and Google Play deployment 3. Basic admin dashboard or API documentation for future maintenance 4. A short video walkthrough or demo session explaining key flows and architecture Acceptance criteria: the builds must pass store review guidelines, sync data reliably between devices, and exhibit sub-second launch times on mid-range hardware. If you’ve shipped productivity apps before, especially cross-platform, I’d love to see them. Let me know which tech stack you’d choose and any questions you have so we can lock down the scope and timeline quickly.
