I need a lean cross-platform mobile app that runs on both iOS and Android. The flow is straightforward: • The user taps a mic button and speaks. • Their speech is converted to text in real time (Google Speech API or any equivalent). If they are offline then also it can convert the tex. • The transcribed line is stored locally—simple file or lightweight database is fine. • A “Send” button opens WhatsApp and shares that saved text alongside a preset payment link. One clean screen is all that’s required; no extra navigation or user accounts. A basic, functional prototype with clear, commented source code and a brief README on build instructions will be enough for this first iteration.
