Cross-platform apps
Flutter applications that share one codebase across iOS and Android with consistent UI and platform-native feel where it matters.

CODEREYES / SERVICE
Mobile apps engineered with the same rigor as your backend.
Flutter cross-platform products for iOS and Android from a single codebase — paired with clean APIs, clear release process, and a partner who already builds the systems your app depends on.
Stack
- Flutter
- Dart
- Node.js
- PostgreSQL
- Firebase
01The Problem
Mobile projects fail when the app and backend are treated separately.
A polished UI shell without solid APIs, release hygiene, or ownership leaves you with something that demos well and breaks in production.
Platform fragmentation
Separate native codebases for iOS and Android double cost and drift features out of sync.
Backend afterthoughts
Apps ship against fragile endpoints, missing auth patterns, or no staging environment.
Performance surprises
Heavy lists, unoptimized images, and chatty APIs make the product feel slow on real devices.
Weak security defaults
Tokens stored carelessly, insecure transport, and unclear session handling create avoidable risk.
Store rejection risk
Missing privacy disclosures, broken deep links, or incomplete review assets stall launch.
No path after launch
The build team disappears — leaving crash reports, OS updates, and feature requests unowned.
02Our Approach
One team for the app, the API, and the release path.
We scope the product, choose a maintainable Flutter stack (or React Native when that fits your existing codebase), design the API contracts, and ship through staged builds you can test before store submission.
Discover
Users, journeys, platforms, compliance constraints, and success metrics.
Architect
App structure, API contracts, auth model, and third-party integrations.
Build
Iterative Flutter delivery with staging builds and reviewable milestones.
Launch & support
Store submission support, monitoring hooks, and a plan for ongoing updates.
03What We Deliver
What we deliver for mobile products.
End-to-end mobile engineering grounded in the web and API work Codereyes already does.
API backends
Authenticated APIs, data models, and integrations in Node.js or PHP — the same stack we use for web products.

Auth flows, push notifications, offline-friendly patterns, media upload, and deep linking when the product needs them.

06Why Codereyes
Why Codereyes for mobile app development.
A technology partner who can own the client, the API, and the hosting context.
Cross-platform efficiency
One Flutter codebase keeps iOS and Android feature-aligned and delivery cost predictable.
Backend ownership
We design the APIs and data layer — not just the screens that call them.
Security-minded defaults
Auth, secrets, and transport patterns treated as product requirements.
Milestone transparency
You review working builds in stages — not a big reveal at the end.
Support after launch
OS updates, crash triage, and small features can continue under a support plan.
Full-stack continuity
Mobile, web, automation, and hosting advice from one accountable team.
07Process
From brief to store-ready builds.
A clear sequence so stakeholders always know what happens next.
Kickoff
Goals, users, platforms, brand assets, and constraints.
Blueprint
Flows, data model, API plan, and technical architecture.
Build loops
Short iterations with installable staging builds.
Harden
Device QA, performance pass, and security basics.
Launch
Store submission support, docs, and next-phase roadmap.
08Results
Outcomes we optimize for.
Qualitative results we aim for — without inventing client metrics or case studies.
One product on both platforms
Shared Flutter foundations so iOS and Android stay feature-aligned.
APIs you can trust
Contracts, auth, and environments designed for mobile clients from day one.
Clearer release path
Staging builds, QA checklists, and store readiness reduce launch surprises.
Maintainable codebase
Structured Dart and typed API clients another engineer can extend without a rewrite.
Room to grow
Architecture that can add features, roles, and integrations without collapsing.
Partner after go-live
A defined support path for updates, incidents, and the next roadmap slice.
09Packages
Scoped mobile products, not fixed boxes.
Mobile apps vary widely by features, platforms, and backend complexity. We usually start with discovery and a blueprint, then build in milestones. Request a custom quote.
