I’m planning a fresh mobile application that functions as a utility tool—think practical, task-focused features rather than social feeds or shopping carts. Because I haven’t locked in a specific platform yet, I’m open to your recommendation on whether we target iOS, Android, or launch on both with a cross-platform framework such as Flutter or React Native. Here’s what I need from you: design, build, and help me test a clean, reliable MVP that feels native, loads quickly, and follows current UI/UX guidelines. We’ll start by mapping core features together, set milestones for each build, then move into iterative testing until the app is stable enough for store submission. If you have experience integrating phone sensors, background services, or lightweight cloud sync, please highlight that—it’s likely we’ll need at least one of those pieces. Source code, working builds, and clear setup documentation should be provided at project hand-off so I can maintain or extend the app later. I’m happy to answer any other technical or business questions you have before we dive in.
