I need an end-to-end Android application that lets users recharge their mobile numbers through a clean, completely bespoke interface. The build must cover three core functions: secure online payment integration, a detailed recharge history for every user, and full user-profile management (signup, login, editable account details). Because I don’t have existing design references, I’m relying on you to propose a fresh, standout UI. Surprise me—feel free to move beyond standard Material Design while still keeping navigation intuitive for regular Android users. Early wireframes or clickable prototypes will help us lock the look and flow before coding begins. Technical expectations • Native development in Kotlin or Java using Android Studio • Payment gateway integration with best-practice security (PCI compliance, tokenization, etc.) • Local data caching plus a scalable backend or API of your choice for transaction records • Clear, commented source code and build instructions so my in-house team can maintain the app Acceptance criteria 1. Fully functional APK that passes real-device tests on the latest two Android versions 2. Seamless payment processing with confirmation receipts stored in the recharge history screen 3. Intuitive profile section supporting registration, login, edit, and logout 4. Custom UI matches the approved prototype without breaking responsiveness on common screen sizes 5. Delivery of source code, assets, and brief deployment guide I’m ready to start once we agree on milestones for design approval, core feature implementation, and final QA.
