Validation & Scope Lock

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.

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 03Days 8–21

The Core Build

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.
