One codebase. Two app stores. No compromises.

We don't build mobile apps that feel like web apps in a wrapper. Nine years of mobile development — React Native that behaves like native, Flutter that ships pixel-perfect on both platforms, and the judgement to know when you actually need Swift or Kotlin. The framework decision matters less than the architecture behind it.

  • Cross-platform
  • 60fps animations
  • OTA updates
  • Typed end-to-end

Why Entalogics for mobile

Four things every
mobile app
actually needs.

Most cross-platform apps we inherit have the same problems — janky scroll performance nobody profiled, navigation that fights the platform instead of following it, a state layer that re-renders the entire screen on every keystroke, and no OTA update strategy. We fix the architecture before the app store reviews do.

Performance01

60fps or users notice. There's no in between.

We profile render cycles from day one. FlatList virtualisation, memoised components, native driver animations. A janky list or a dropped frame isn't a cosmetic issue — it's a one-star review.

Architecture02

Feature modules, not a screens folder.

Each feature owns its screens, hooks, types, and tests. Navigation is typed. Shared components live in a design system package. Two engineers work on two features without merge conflicts.

State03

Server state and client state don't belong in the same store.

TanStack Query for server data. Zustand or Jotai for local UI state. URL-like deep link state handled by the router. Less global state, fewer re-renders, faster screens.

Type safety04

TypeScript strict, from API contract to component prop.

Zod-validated API responses. Typed navigation params. Typed design tokens. When the backend changes a field, the app fails to compile — not to render in a customer's hand.

When cross-platform, when native

Mobile is a tool decision.
Not a tribal one.

React Native, Flutter, or fully native — each has a real trade-off. We'll tell you on the first call which one fits your product, your team, and your timeline.

PICK REACT NATIVE WHEN

  • Your team knows JavaScript/TypeScript — the ramp-up is near zero
  • You want to share logic and types with your Next.js or Node.js web stack
  • OTA updates via Expo EAS matter — skip the app store review for JS bundle fixes
  • Hiring pool is a constraint — JavaScript developers are everywhere

PICK FLUTTER WHEN

  • Pixel-perfect custom UI is the product — Flutter renders every pixel on its own canvas
  • You need iOS, Android, web, and desktop from one codebase
  • Animation-heavy or graphics-heavy product where Impeller's GPU rendering earns its place
  • Your team doesn't have JavaScript baggage and can invest in learning Dart

GO NATIVE WHEN

  • Deep hardware integration — Bluetooth, ARKit, camera pipelines — where the abstraction layer costs more than it saves
  • App size and startup time are hard requirements under 5MB
  • Platform-specific UX is non-negotiable and the budget supports two codebases

WE SAY NO WHEN

  • "Wrap our website in a WebView and call it an app." That's not mobile development.
  • "Build it in Flutter because someone read an article." We'll tell you honestly if React Native fits better.
  • "We need both apps in three weeks." That ship has sailed.

What we build for mobile

Six product surfaces.
One quality bar.

The shapes of mobile work we ship most. Each built for the app store — not a demo.

  • S01

    Consumer apps

    Onboarding flows, push notifications, in-app purchases, analytics. The full consumer mobile stack — polished to pass app store review on the first submission.

  • S02

    SaaS companion apps

    Your web dashboard, in your user's pocket. Offline-first sync, biometric auth, push notifications tied to backend events.

  • S03

    E-commerce mobile apps

    Product browse, cart, checkout, order tracking. Native-feel scroll performance on product lists with hundreds of SKUs.

    Internal field apps

    Barcode scanning, offline data collection, GPS tracking, photo capture. Tools for teams that work outside the office.

    Flutter brand apps

    Pixel-perfect brand experiences where every animation, transition, and micro-interaction is custom. Flutter's rendering engine earns its place here.

    Swift or Kotlin modules for Bluetooth, ARKit, camera, or codec work — integrated into a cross-platform shell or shipped standalone.

The playbook

Patterns we
ship on repeat.

Mobile patterns proven in production — not conference demo apps.

  • P01

    Expo-first for React Native

    Expo managed workflow by default. EAS Build for cloud compilation. EAS Update for OTA JavaScript patches that skip app store review. Eject to bare only when a native module genuinely demands it.

  • P02

    Typed navigation

    Every route, every param, typed end-to-end. A screen refactor that changes a param type fails the build — not the QA pass three days later.

  • P03

    Server state via TanStack Query

    Cache-first, background refetch, optimistic updates. No manual loading/error/success state management. Screens show data instantly from cache and refresh silently behind the scenes.

  • P04

    Design tokens across platforms

    Colour, spacing, typography as code — shared between iOS and Android. Light/dark mode, dynamic type, and brand variants from a single token source.

  • P05

    Detox or Maestro for E2E tests

    Real device E2E tests on critical user flows — onboarding, purchase, deep link. Runs in CI on every PR. Catches the regression a unit test can't.

  • P06

    OTA updates with rollback

    EAS Update for React Native, Shorebird for Flutter. Push a fix to production without waiting for app store review. Rollback if the update degrades a metric.

Signature case

A consumer app,
rebuilt from WebView to React Native.

A B2C fintech app wrapped in a WebView — 4.2s cold start, 3.1-star average rating, scroll jank on every list, and push notifications that arrived 30 seconds late because the WebView had to wake up first. Rebuilt in React Native with Expo, TanStack Query, and native push in 10 weeks. Rating climbed to 4.7 within two months.

Before

Cold start 4.2s · rating 3.1★ · WebView scroll jank · push delay 30s · no OTA updates

After

Cold start 1.1s · rating 4.7★ · native FlatList at 60fps · instant push · EAS OTA live

  • Cold start improvement−74%
  • App store rating+52%
  • To fully rebuilt10wk
  • Shipped regressions0

Engagement shape

Eight to ten weeks
to a measurable ship.

A typical mobile engagement, end-to-end. We build or rebuild screen by screen — never a six-month big bang. The current app stays live while we work.

  • W01

    Audit + RFC

    Two senior mobile engineers on the project. Render profiling, navigation audit, state architecture review. A ranked, dollarized RFC.

  • W02–03

    Foundation + first screen

    Expo or Flutter baseline, design tokens, typed navigation, one production screen built end-to-end. Real performance numbers on a physical device.

  • W04–08

    Build screen by screen

    Feature by feature under feature flags. TestFlight and internal track releases weekly. Your roadmap keeps moving.

  • W09+

    App store submission + handoff

    Store assets, review guidelines compliance, first submission. Runbook handed to your team — or we stay on retainer.

FAQ

Sharp questions,
straight answers.

React Native vs Flutter, PWAs, rebuilds — the questions we get on every mobile discovery call.
React Native if your team knows JavaScript and you want to share code with your web stack. Flutter if pixel-perfect custom UI is the product and your team can invest in Dart. For most SaaS and consumer apps, React Native with Expo ships faster and has a larger hiring pool.
PWA if your users come from web search and don't need push notifications, offline access, or native hardware. Native app if you need the app store, push, biometrics, or a first-class mobile experience. We'll tell you which one on the first call.
Yes. We audit every native API usage, map it to a cross-platform equivalent or Turbo Module, and rebuild screen by screen. The existing app stays live on the stores until the new one is ready.
Yes. The engineers who write the RFC ship the code. No handoff mid-engagement. Direct access throughout.
Yes. We adapt to your navigation library, state management, and testing setup. If something structural needs changing, we flag it in the RFC. If it works, we build on top of it.
