№ 01 · The Problem

Most app builds
die quietly
in staging
for six months.

Issue A

The "prototype" that never shipped.

You paid $40K for an app. Eight months later, you have a Figma file, a half-working iOS build that crashes on the login screen, and an Android version that "needs more time." The agency keeps moving the goalposts. "We're just refactoring." "We're waiting on the backend." "We need one more sprint." The app is a hostage. Your money is gone. The launch keeps slipping.

Issue B

"Native iOS + Android" = 2× the bill.

The agency tells you native is the only "real" way. They charge you twice, once for an iOS team writing Swift, once for an Android team writing Kotlin. Two codebases. Two bug surfaces. Two release schedules. One app launches three months before the other, every feature ships twice, and every bug fix needs two patches. You're paying 2× for an app where Flutter would have shipped both stores from one codebase.

Issue C

App Store rejected. Twice. No warning.

The agency submitted the build, said "we're live next week," then radio silence. Two weeks later you find out Apple rejected it for missing privacy declarations, broken sign-in-with-Apple flow, or guideline 4.3 ("spam"). The agency had never read Apple's review guidelines. Now they're learning on your timeline, your budget, and your launch date. App Store review is not a checkbox. It's a discipline.

Issue D

Six months in, it still doesn't work offline.

The app works perfectly in the agency's office on their fiber connection. Then your delivery drivers take it into a basement, an elevator, or a tunnel, and the app freezes, drops orders, or shows a generic "something went wrong" error. Mobile is not desktop in a smaller window. Network state matters. Offline behavior matters. Most agencies treat mobile like web, then act surprised when it falls over in the real world.

№ 02 · The Approach

One codebase.
Two app stores. Real ship dates.

Flutter-first because it actually works at production scale. React Native when your team needs it. Native when the use case demands it. honest tech choices.
Pillar №01 New Apps

Greenfield builds

From idea to App Store in 12–20 weeks. Flutter primary, one codebase to iOS + Android. Backend selection that fits the use case (Firebase for fast MVPs, Supabase for SQL needs, custom Node/Laravel when business logic is complex). Real UX. Real offline handling. Real push notifications.

Built mobile-first (because they're mobile apps, novel concept). Built with App Store and Play Store review baked into the timeline, not bolted on after launch slips.

Flutter MVPs Backend Selection Store Submission Push + Auth
Pillar №02 App Rescue

Rescue missions

For apps already half-built, behind schedule, or live and broken. We take over from agencies that couldn't finish. Audit the codebase. Identify what's salvageable. Refactor what isn't. Ship what's been stuck in staging.

App modernization for older builds, migrating from deprecated SDKs, fixing iOS 17/18 compatibility, restoring App Store compliance after rejections. The work most agencies refuse because someone else wrote the code. We don't refuse. We finish.

№ 03 · What's Inside the File

Six sub-disciplines
under one mobile team.

Every app engagement is assembled from these six modules. Pick the ones you need. We'll tell you which. Most builds use 4 to 5 simultaneously. The audit clarifies which.

Module №01Primary

Flutter development

Our primary mobile stack. One Dart codebase compiled to native iOS + Android. Production-grade performance, native UI feel, fast dev velocity, single bug surface.

  • Cross-platform iOS + Android (one codebase)
  • Custom widgets & design systems
  • Native module integration when needed
  • State management (Riverpod / Bloc)
  • Offline-first architecture
  • App Store + Play Store deployment
Module №02Alt Stack

React Native

When Flutter isn't the right fit. React Native for teams already invested in the React ecosystem or where deep native module integration is the core requirement.

  • React Native + Expo / bare workflow
  • Native module bridging
  • TypeScript-first development
  • Redux / Zustand state
  • OTA updates (CodePush / Expo Updates)
  • Migration from older RN versions
Module №03Web-Mobile

Progressive Web Apps

For when you need mobile reach without App Store overhead. Installable PWAs with offline support, push notifications, and add-to-home-screen.

  • Installable PWA architecture
  • Service worker + offline caching
  • Web push notifications
  • App-store-free distribution
  • Lighthouse-optimized performance
  • Hybrid PWA + Trusted Web Activity
Module №04Backend

Backend & APIs

Every app needs a backend. Firebase for fast MVPs. Supabase when you need SQL. Custom Node.js or Laravel APIs when business logic is real. We integrate with your existing backend when you have one.

  • Firebase (Auth, Firestore, Functions)
  • Supabase (Postgres + realtime)
  • Custom REST + GraphQL APIs
  • Payments (Stripe, RevenueCat, JazzCash)
  • Push notifications (FCM, APNs, OneSignal)
  • Existing-backend integration
Module №05Critical

Store submission & ASO

The discipline most agencies skip until launch week. App Store Optimization, privacy declarations, review-guideline compliance, screenshot strategy, metadata copywriting.

  • App Store + Play Store submission
  • ASO keyword research
  • Screenshot + preview video design
  • Privacy policy + data declarations
  • Review-guideline pre-audit
  • Rejection-cycle handling
Module №06Retainer

Maintenance & growth

Apps aren't websites. iOS and Android push major OS updates yearly. SDKs deprecate. Crash reports need handling. Monthly retainers covering updates, crashlytics monitoring, feature drops, and store re-submissions.

  • iOS + Android OS-update compatibility
  • SDK + framework upgrades
  • Crashlytics monitoring + fixes
  • Feature-drop release cycles
  • Store re-submissions
  • Analytics + funnel optimization

№ 07 · The Answers

Questions you'd actually ask.

The honest answers. Including the ones most agencies dodge. If yours isn't here, email us. We'll answer it directly.

Flutter is our primary stack. One codebase ships to both iOS and Android, the performance is near-native, and the dev velocity is significantly faster. React Native makes sense when your team already has React expertise or when you need very deep native module integration. For most projects we recommend Flutter. We'll tell you honestly which fits your use case after the audit.
An MVP Flutter app typically takes 8–12 weeks. A production app with backend, payments, push notifications, and App Store submission runs 12–20 weeks. Complex apps with offline-first sync, real-time features, or hardware integration can run 16–24 weeks. Anyone quoting an app build in 4 weeks is either shipping a wrapped website or lying.
Yes. App Store and Play Store submissions are part of every engagement, not extras. That includes screenshots, metadata, App Store Optimization (ASO), privacy declarations, age ratings, and handling rejection cycles. We have shipped apps to the App Store and we know how the review process actually works. Not theory — practice.
Most apps need at least partial offline behavior. We architect offline-first when the use case demands it (field service apps, point-of-sale, content readers). For e-commerce and SaaS apps we handle network state gracefully with cached responses and retry logic. We don't pretend every app needs full sync, but every app gets thoughtful network handling. Mobile is not desktop in a smaller window.
Depends on the app. Firebase for fast MVPs, real-time chat, push notifications, and auth. Supabase when you want SQL and self-hosting options. Custom Node.js or Laravel APIs when the business logic is complex or already exists. We integrate with your existing backend if you have one. We don't push a single stack because we don't take affiliate fees.
MVP Flutter apps typically range from $8,000 to $20,000. Production apps with full backend, payments, push, and App Store submission run $20,000 to $50,000. Complex builds with offline sync, real-time features, or specialized integrations can run higher. Maintenance retainers start at $1,500/month. Quotes are itemized by feature. No "mystery app pricing" — you see what every module costs.
