I need a straightforward proof-of-concept for a mobile AI that builds my daily timetable and rings me with an automated call right when each activity starts. Scope • One cross-platform mobile build (iOS and Android) is enough; feel free to use Flutter, React Native or any similar framework. • Core flow: user enters their tasks → the AI arranges them into an optimized schedule → the app triggers a voice call to my phone at the scheduled times. • Basic extras I want working from day one: – Task prioritization so urgent items surface first. – Automatic time-zone adjustments when the phone location changes. – Simple voice commands (e.g., “Add gym at 6 pm”) using any reliable speech-to-text API. What I consider a finished deliverable 1. Source code repository with clear setup instructions. 2. An APK/TestFlight build I can install and test. 3. Short README explaining how the call reminder is implemented (Twilio, Firebase Cloud Functions, etc.) and where to plug in API keys. Keep UI minimal—just enough screens to enter tasks and see the generated timetable. I’m aiming for a lean demo I can validate quickly, so please focus on clean, working logic over polished visuals.
