Design a Fun Cartoonish GIG app allowing customers (receivers) to click app or link to easily book my flat-rate, on-demand courier service. It must work perfectly on iOS, Android, have a Windows desktop client, and fully responsive web portal. Receivers will select a PickUp Date prompting Carriers to accept a package based on when the Carrier's PickUp Site arrival date. When Carrier accepts, the Receiver gets a confirmed Carrier's shipping address to forward predetermined packaging and compliant online only orders that meet limitations. Receiver shares any special instructions, all order tracking updates & details. Once Carrier confirms & posts to transaction receipt of all orders, Carrier MUST post CLEAR pictures/video and pack all in the bag provided according to instructions. Carrier checks in packages to Arrival Bin Storage which notifies Receiver who then has free 24hr storage that incurs a fee every 3hrs over and paid option for delivery based on proximity. Receiver confirms receipt of their package. Core features needed: • Delivery tracking: real-time updates with map views. • Storage management: Carrier checks package into warehouse bin and then Receiver is prompted to pick up, pay a fee every 3 hours over 24 hours, or choose our fee/proximity based delivery. • Payment integration: safe in-app or online checkout before a driver is sent out. All requests should come from the app or website; real-time chat support feature. A clean UI/UX, a well-documented API, and ready-to-deploy builds for each platform, along with full source code and hand-over notes.
