Our Process: Flutter App Launched in 28 Days

Phase 01

Validation & Scope Lock

Days 1–3

Isolate the single core feature your app must deliver and lock the technical scope.

Day 1 · Discovery Workshop:A focused 90-minute session to map the primary user journey, identify non-negotiable MVP features, and defer everything else to Version 2.
Day 2 · Architecture & Module Selection:Technical specification mapping data models, database structures, and battle-tested Flutter modules for auth, storage, and payment integrations.
Day 3 · Fixed-Scope Agreement:Receipt of a guaranteed fixed-scope, fixed-price contract. Scope is firmly locked to ensure delivery within the 28-day sprint.

Phase 02

Days 4–7

High-fidelity UI design and an interactive prototype tested directly on your phone.

Days 4–5 · UX & UI Component Assembly:Creation of high-fidelity screen designs adapted to your brand identity, focusing strictly on the locked core user journeys.
Day 6 · Interactive Prototype:Screens linked into a realistic, clickable mobile prototype so you can experience navigation and gesture flow on real hardware.
Day 7 · Review & Visual Sign-Off:A live walkthrough with immediate real-time adjustments on the call, resulting in final visual approval before code begins.

Phase 03

Days 8–21

Heads-down engineering compiling a single Flutter codebase simultaneously for iOS and Android.

Days 8–14 · Foundation & Frontend:Deployment of production infrastructure, auth systems, and database schema while building pixel-perfect UI matching the signed-off prototype.
Days 15–21 · Business Logic & API Integrations:Wiring state management, offline persistence, and external services such as Stripe payments, push notifications, and geolocation.
