# joymajumdar2001/watery architecture > Architecture diagram of the GitHub repository joymajumdar2001/watery, generated by GitDiagram from its file tree, README and a sample of source files (last updated 2026-11-14). It is an AI-made overview: check details against the source. - Interactive diagram: https://gitdiagram.com/joymajumdar2001/watery - Repository: https://github.com/joymajumdar2001/watery ## Overview Watery is an Android water-delivery commerce app. Customers authenticate, browse products, build a local cart, choose a delivery location and phone number, pay online or by cash on delivery, then view and track orders. Delivery partners log in, review orders, and update their fulfillment status. The README documents Appwrite for authentication, product/order data and images, plus Razorpay and map/location integrations. Edges are limited to relationships shown in sampled source or explicitly described in the README; some screens and integrations are unsampled.
