I need a small but reliable application that can ethically collect publicly available product details—name, description, price and SKU—from Android-only apps. The tool must log in (when credentials are supplied), navigate any in-app catalogue structure and export everything into a clean, structured format of my choice: CSV. Core expectations • Work exclusively with Android mobile apps (no website scraping involved). • Capture at minimum the four key fields mentioned, plus any other common identifiers you discover that help SKU mapping and price comparison. • Respect the target app’s T&Cs and rate-limit requests so the process remains ethical and unobtrusive. • Output files must be clean—no duplicate rows, broken encodings or orphaned line breaks. • Include a concise training guide that shows me how to run, update and extend the scraper in the future (screenshots or a short Loom video are both fine). I’ll confirm the specific retail apps after we start, but assume standard e-commerce layouts and APIs. Code can be in Python only. Please tell me how you plan to handle in-app API calls or dynamic content, and roughly how long the first working pass will take once you get the app list.
