Zomee — Hyperlocal Delivery Platform
India
Hyperlocal On-Demand Delivery Super-App with 10-Minute Delivery Promise. ATS built Zomee using Flutter for cross-platform mobile development, delivering native-smooth animations and interactions on both iOS and Android from a single Dart codebase.
The challenge
Why this project mattered
The hyperlocal delivery market demands sub-second app responsiveness, real-time order tracking, and seamless multi-party coordination between customers, delivery partners, and merchant outlets. Building separate iOS and Android apps would have been cost-prohibitive for the startup, while a web-first approach would not deliver the native-quality UX needed to compete with established delivery giants.
What we built
The delivery
ATS built Zomee using Flutter for cross-platform mobile development, delivering native-smooth animations and interactions on both iOS and Android from a single Dart codebase. FastAPI provided a high-performance, async Python backend capable of handling thousands of concurrent order events with minimal latency. Three distinct app personas were built within the single Flutter project: the Customer App (discovery, ordering, live tracking), the Delivery Partner App (order acceptance, navigation, proof of delivery), and the Merchant Dashboard App (inventory management, order fulfilment, analytics). Firebase Firestore enabled real-time order state synchronisation across all parties.
