Material You / Material 3 Mobile App Design

Design a complete productivity mobile app in modern Material You / Material 3 style with dynamic theming, covering the entire user journey from splash, onboarding, sign-up and login to home dashboard, tasks, calendar, projects, focus timer, notes, reminders, search, notifications, profile, settings, and all supporting screens. Use adaptive color palettes generated from the user's chosen theme or wallpaper, expressive typography, large rounded cards, tonal surfaces, pill-shaped controls, floating action buttons, intuitive bottom navigation, clear visual hierarchy, generous spacing, subtle elevation, smooth transitions, responsive micro-interactions, and accessible touch targets. Make every screen visually consistent yet dynamically personalized, with light and dark modes, polished empty and loading states, intuitive gestures, and a clean, friendly, highly functional Android-first experience that feels native, modern, expressive, and effortless to use.
