One codebase. iOS, Android & Web.

Flutter and React Native apps that look and perform like native — shipped to all platforms simultaneously, maintained as one codebase, at a fraction of the cost of building separately.

60fps animations, lazy loading, optimised assets, and offline-capable architecture for real-world networks.
Delivery Process

How we deliver it

Every phase is timeboxed and has clear deliverables — you always know what's happening and what's next.

01

Platform Strategy Week 1

Decide Flutter vs React Native, define shared vs platform-specific UX, and map the offline/online data model.

02

Design Week 2–4

Platform-adaptive UI — feels at home on iOS and Android. Component library built in Figma first.

03

Core Build Week 4–10

Feature sprints with working TestFlight/Play Console builds every two weeks for your testing team.

04

Native Integration Week 8–11

Device APIs, push notifications, biometric auth, payment SDKs, and any platform-specific requirements.

05

Launch Week 11–14

App Store review preparation, launch coordination, crash monitoring setup, and v2 roadmap.
