I have a concept that needs to be translated into a fully-functional mobile application. At this stage I am certain it has to be a mobile app, but I’m still deciding whether to launch first on iOS, Android, or ship a cross-platform build that covers both from day one. Likewise, the core purpose—be it e-commerce, social networking, or a productivity tool—will be finalised once I review the technical possibilities and UX options with you. The job covers everything from early ideation through to store release: • Low-fidelity wireframes or clickable prototype that captures the user journey • Pixel-perfect UI design, aligned with current platform guidelines • Front-end and back-end development with clean, well-documented code • Basic analytics, push notifications, and in-app authentication • Testing on real devices, bug fixing, submission and approval in the relevant app store(s) • Handover of full source code and build instructions Acceptance criteria • Build installs successfully on at least one platform (Android APK or iOS TestFlight link) • All agreed screens and flows are functional, free of critical bugs • Code and documentation are delivered in a version-controlled repository Please outline your preferred tech stack, any past projects that show similar scope, and an estimated timeline from kickoff to store approval.
