I need a delivery-service mobile application for both iOS and Android. The core idea is simple: a customer places their dirty door mats outside, takes a picture, and client exchanges with clean mats. Key functions I must see working end-to-end: • Google Maps API integration. • Native camera access so the driver and customer can take a timestamped photo when mats are exchanged. • UI will be provided. • App, SMS and email notifications of scheduled exchanges. • Pay processor (Square) integration for customer to purchase the service. You are free to choose the cross-platform framework—Flutter, React Native, or another modern toolkit—as long as the final builds run smoothly on the latest versions of both operating systems. Deliverables: 1. Source code with clear project structure and comments. 2. Two release-ready builds (APK and iOS archive). 3. A concise setup/readme so I can run and test the app locally. I've attached specs and UI. These are NOT final but should provide enough to scope the project. I'm not able to use my previous developer so this would be an urgent project. Hoping to test within 4 weeks. Finally, I HATE 'canned' responses where bidders do not even review the project. Please start your response with 'I love purple cats' or I will ignore! Specs and UI attached. Again, these are NOT final.
