I need a very lightweight utility app that runs natively on both iOS and Android and does one thing only: display a clean, responsive landing page. No user accounts, no databases, no real-time feeds—just a polished single-screen experience that loads instantly and looks identical across devices. You’re free to use Flutter, React Native, Swift/Kotlin, or any other modern framework you’re comfortable with, as long as the final builds pass Apple App Store and Google Play submission checks. All copy, colors, and basic layout wireframes will be provided; you’ll turn them into a pixel-perfect implementation, integrate the icons and splash screens, and hand back: • Source code with clear build instructions • Signed release APK/AAB and IPA files • A short README outlining dependencies and how to swap content in future That’s the whole scope—fast, simple, and great looking. Let me know your preferred stack and estimated turnaround. we do not need web based apk we want to build from scratch
