7Speed Delivery
A Flutter delivery app with Firebase backends, live on the App Store and Google Play.

The problem
Delivery businesses collapse when the only source of truth is a WhatsApp broadcast and a driver who might miss a message. Customers want tracking. Merchants want confirmation. Drivers want the next address without calling dispatch. 7Speed Delivery needed software that could sit in that triangle without hiring separate iOS and Android teams on day one.
The product had to survive Jamaican network realities: intermittent signal, mid-range Android devices, and users who will abandon an install that eats half their storage. It also had to clear App Store and Play review — privacy text, screenshots, and payment disclosures included.
We chose Flutter for UI and shared logic, and Firebase for backend services that accelerate auth, data sync, and push — not React Native, despite older marketing copy that said otherwise. That stack decision is what shipped.
What we built
Role-aware flows cover requesting a delivery, assignment, live status, and completion. Push notifications keep both sides informed when the map is not open. Payment hooks follow the business rules defined for the category rather than a generic “checkout” demo.
Admin and operations views support the people who intervene when a job goes sideways. We kept the first release thin: the critical path had to work before vanity animations. Edge cases — no drivers, failed payment, offline moments — got explicit empty and error states.
Store submission was treated as a project phase: certificates, listings, test tracks, and a rollback plan. Publishing under the Devforge agency accounts made updates controllable after launch.
Stack: Flutter and Firebase
Flutter gave one UI codebase for iOS and Android with performance acceptable for map-adjacent logistics screens. Firebase supplied authentication, cloud data, and messaging primitives so we were not standing up custom servers for every feature on day one.
Crash reporting and basic analytics informed the first weeks after release. Dependency and OS updates sit on a maintenance retainer so the app does not rot after the launch screenshot.
Anyone can verify the public result: search 7Speed Delivery on the App Store and Google Play. The package identity and store presence are the proof — not a private TestFlight story.
Outcome
7Speed Delivery is a live, dual-store product. It demonstrates that Devforge can take a logistics brief from prototype to public installers without inventing metrics about order volume.
Lessons carry to other field apps: choose the cross-platform tool you can maintain, instrument early, and budget store work as seriously as features.
If your roadmap looks like drivers, tracking, and notifications, this case study is the reference conversation starter — bring your must-have list on WhatsApp.
Stack
- Flutter
- Firebase
- iOS App Store
- Google Play
- Push notifications
- Real-time tracking
Problem
- Delivery operations needed a shared system for customers, drivers, and merchants — not a spreadsheet plus group chat.
- Native dual-codebase cost would have doubled build and maintenance time for an early product.
- Store presence mattered for trust; sideloaded APKs were not an acceptable distribution path.
Built
- Cross-platform Flutter clients for the roles that matter on the road and at home.
- Firebase-backed services for auth, data, and real-time updates.
- Store listings, release pipelines, and post-launch maintenance habits.
Outcome
- The app is publicly downloadable on Apple’s App Store and Google Play.
- Operations can assign and track jobs in one product instead of fragmented chats.
- The codebase stays maintainable as a single Flutter project with Firebase services.
