Hello There, ✨ Warm Greetings ✨ Thank you for sharing your requirement for a cross-platform utility/productivity mobile app. I’ve gone through your needs and this aligns well with my expertise in Swift, Kotlin, and React Native. Before proceeding, I’d like to clarify a couple of key points: ✅ Do you prefer a native build (Swift/Kotlin) or a single codebase approach (React Native/Flutter)? ✅ Will the app need real-time backend integration (e.g., Firebase, AWS) or just local storage? ⚡ I am available to provide a complete solution with performance-optimized code, intuitive UI/UX, and guidance for smooth app store submission. From your end, I’ll need brand guidelines, feature priority list, and access (if backend exists). With these, I can deliver initial wireframes within 24–36 hours.
