Flutter apps built for real-world operations

Neoul is a Seoul-based product studio that designs and builds Flutter applications for founders who need consumer apps, operational tools, and admin workflows in one delivery cycle. We write the product in-house—no subcontractors—and show working builds every two to three weeks.

Who this service is for

  • Founders launching an iOS and Android product from a single codebase
  • Operators who need member, staff, or store-facing apps tied to real workflows
  • Teams that want design, mobile development, and backend integration handled by one in-house studio
  • Buyers who need visible progress, milestone approvals, and full source ownership at handover

Problems Neoul solves

  • Fragmented native teams that drift out of sync across iOS and Android releases
  • Black-box outsourcing where scope, subcontractors, and progress are hard to verify
  • Apps designed in isolation from the admin systems that keep operations running
  • Late surprises when authentication, notifications, or data models were never planned with the product

What Neoul builds

  • Consumer and operational Flutter apps for iOS and Android
  • Shared UI systems and flows designed in Figma before engineering begins
  • Firebase-backed authentication, data, and push notification wiring
  • Flutter Web or web admin dashboards that support the same product
  • Release-ready builds with handover of source code and design files

Typical deliverables

  • Product discovery and scoped feature list for launch
  • Approved Figma screens for key user journeys
  • Flutter application for iOS and Android
  • Backend and admin integration required for the agreed scope
  • Working demos every two to three weeks during the build
  • Source code, design files, and six months of bug-fix support for reproducible defects

Development process

Discovery

We define goals, users, and the core scope that must ship first.

Planning

We map product structure, roles, and user flows before design expands.

Design

Key screens are designed in Figma and require written approval before development.

Build

You receive a working Flutter build every two to three weeks—not mockups only.

Handover

You receive the complete source code, design files, and six months of bug-fix support.

Technical considerations

  • One Flutter codebase for iOS and Android with a consistent release cycle
  • Architecture planned around real roles, offline-tolerant flows, and admin operations
  • Firebase or other backend choices selected for auth, data, and notifications—not as an afterthought
  • App Store and Play release support as part of delivery when included in scope
  • Room for post-launch iteration without rewriting the foundation
