Mobile app architecture means the decisions that outlive the first release — native Swift and Kotlin versus a React Native or Flutter runtime, where server state ends and UI state begins, how offline sync and push get wired, and what a release pipeline needs so a fix reaches phones without waiting a week for review. This is what separates an app that holds up after version one from one that gets rebuilt at version three.
Why Entalogics for mobile
Cross-platform apps that come to us tend to have the same four problems: scroll performance nobody profiled, navigation that fights the platform, a state layer that re-renders the whole screen on every keystroke, and no plan for over-the-air updates. We fix the architecture before the store reviews point it out.
We profile render cycles from the start: list virtualisation, memoised components, animations on the native driver. A dropped frame or a sluggish list reads as a one-star review, not a cosmetic issue.
Each feature owns its screens, hooks, types, and tests. Navigation is typed. Shared components live in a design-system package. Two engineers can work on two features without merge conflicts eating the sprint.
TanStack Query for server data. Zustand or Jotai for local UI state. Deep link state handled by the router. Less global state means fewer re-renders, faster screens, and a codebase the next developer can read.
Zod-validated API responses, typed navigation params, typed design tokens. If the backend renames a field, the app fails to compile instead of failing on someone's phone.
When cross-platform, when native
React Native, Flutter, or native iOS and Android each come with trade-offs. On the first call we'll tell you which one fits your product, your team, and your timeline. We don't have a favourite.

What we build for mobile
The kinds of mobile app we build most often, all of them built for the App Store and Google Play rather than for a demo on an engineer's phone.
Onboarding flows, push notifications, in-app purchases, analytics — the full consumer mobile stack polished to pass App Store and Play Store review on the first submission.
Your web dashboard, in your user's pocket. Offline-first sync, biometric auth, push notifications tied to backend events.
Product browsing, cart, checkout, and order tracking, with scroll performance that holds up on product lists of hundreds of SKUs.
Barcode scanning, offline data collection, GPS tracking, photo capture — native iOS and Android tools for teams working outside the office.
Pixel-perfect brand experiences where every animation, transition, and micro-interaction is custom. Flutter's GPU rendering earns its place here.
Swift or Kotlin modules for Bluetooth, ARKit, camera, or codec work — integrated into a cross-platform shell or shipped as standalone native iOS and Android apps.
The playbook
The patterns we use on production mobile apps.
P01
Expo managed workflow by default, EAS Build for cloud compilation, EAS Update for OTA patches that skip app store review. Eject to bare only when a native module requires it.
P02
Every route and every param typed end to end. If a refactor changes a param type, the build fails, rather than QA finding it three days later.
P03
Cache-first, background refetch, optimistic updates. No manual loading/error/success state spread across every mobile screen. Data shows instantly from cache and refreshes silently.
P04
Colour, spacing, and typography as code — shared between iOS and Android. Light/dark mode, dynamic type, and brand variants from one token source.
P05
End-to-end tests on real devices for the flows that matter: onboarding, purchase, deep links. They catch the regressions unit tests can't.
P06
EAS Update for React Native, Shorebird for Flutter. Push a fix to production without waiting for App Store or Play Store review. Rollback if the update degrades a metric.
Signature case
Sociall needed one app for every social platform — feeds from Instagram, X, Facebook, TikTok, and LinkedIn with the ads and algorithmic noise stripped out. The architecture that made it work: a React Native UI over an embedded Chromium engine, so each platform's web interface renders natively inside the app with ad blocking and content filtering applied at the browser level, plus AI fact-checking on top. Seven months from kickoff to the App Store.
Before
Five separate social apps · ads and suggested posts everywhere · no control over the feed
After
One iOS app · every feed ad-free at the browser level · AI fact-checking · 4.6★ at launch
Engagement shape
A typical engagement, end to end. Screen by screen rather than a six-month big bang, with the current app live the whole time.
Two senior mobile developers on the project. Render profiling, navigation audit, state architecture review. The output is a ranked RFC with effort estimates against each item.
Expo or Flutter baseline, design tokens set up, typed navigation wired in, and one production screen built end to end. Performance numbers come from a physical device.
Feature by feature under feature flags. TestFlight and internal Play Store track releases weekly. Your roadmap keeps moving throughout.
Store assets, review guideline compliance, first submission to both stores. App Store review typically takes 1–2 business days. Runbook handed to your team — or we stay on retainer.
Stack
The default stack for production mobile work.
Verified feedback from Upwork, Clutch, and reference calls we're happy to set up before you sign anything.
CEO, Modestly
Entalogics has successfully delivered extension prototypes on time, and we are impressed with their project management and the finished product. The client communicates with Entalogics via virtual meetings, email, and messaging apps.
Founder, Flourish Schools
Collaborating with Entalogics was a great experience. Communication was clear, we aligned quickly, and their team delivered high-quality code on time with thoughtful technical decisions.
CTO, SentryBay
Their Chromium expertise helped us ship a hardened browser with live threat controls and enterprise rollout support. Security operations became significantly faster.
Founder, G3 Ventures LLC
Entalogics delivered our custom Electron browser in six months with isolated profile workflows and stable policy sync. Agent onboarding improved by 55% after rollout.
Project Manager, Sociall
Entalogics built our iOS Chromium-based mobile app with a smooth native feel, stable media rendering, and reliable sync. We shipped faster and improved engagement after launch.
RozmeriGPT
The web dashboard and Chrome extension now share prompts, billing, and analytics in one platform. Our content turnaround improved 4x after launch.
Project Manager, Omni Browser
Entalogics built our Omni Browser on top of Chromium with deep product-level execution. They implemented an integrated VPN and Omni Crypto Wallet directly in the browser, made strong architectural decisions, and delivered quality code on schedule with clear communication.
Project Manager, Digital Office: Aura
Entalogics built Digital Office: Aura as a custom Chromium-based authentication platform. Their team modified Chromium internals and integrated our manual custom authentication flow with reliable implementation, fast delivery, and consistent communication.
Engagement
Nothing here bills by the hour. Every option is either a fixed quote or an openly stated rate.
One product, scoped and priced once, built entirely by senior mobile developers. RFC to App Store submission in 10–14 weeks.
FIXED SCOPE
That's a different page for a different buyer — a mobile engineer matched to your platform, priced per engineer per month, embedded in your repo and standups.
PER ENGINEER
For product teams that want a long-term mobile partner rather than a one-off build: cross-platform architecture, a performance programme, and help with hiring.
