High-Performance iOS & Android Mobile Apps from a Single Codebase
Fluid 60fps gestures, offline-first synchronization, and native device speed on both iPhone and Android. Building separate iOS and Android native apps doubles your development costs and slows feature updates to a crawl. We engineer cross-platform mobile apps using Flutter and React Native that feel completely indistinguishable from high-end platform-native software.
One Codebase. Two App Stores. Zero Compromises.
Mobile users expect instant responsiveness, smooth animations, and the ability to work even when internet connectivity drops. If an app stutters or shows a blank loading spinner, it gets deleted.
Team Axiogen engineers production mobile applications that combine native device APIs (biometrics, camera, GPS, Bluetooth, push notifications) with unified cross-platform runtimes. We maintain a single, clean TypeScript or Dart codebase that compiles to native ARM binaries for iOS and Android.
From architectural design and offline SQLite/WatermelonDB state synchronization to Google Play and Apple App Store review approvals, we manage the complete lifecycle so your product reaches millions of smartphone users flawlessly.

How We Deliver: 4-Step Engineering Process
Mobile User Flow & Screen Architecture
We map out navigation tabs, bottom sheets, gesture interactions, and onboarding screens in Figma.
Core Functionality & Offline Database
We build the core application, implement local persistence, and integrate device sensors and push notifications.
Real Device QA & Battery Profiling
We test on real iPhones, budget Android phones, and tablets to ensure 60fps performance and zero memory leaks.
App Store & Play Store Approval
We prepare app screenshots, write metadata descriptions, submit to Apple and Google, and manage the review process.
ClinicOS: Native Patient Token Calling & TV Queue Sync
Built real-time synchronized mobile interfaces for consulting doctors with sub-50ms token broadcast.
Client / Architecture: Axiogen Healthcare SystemsFrequently Asked Questions
Direct answers to common questions about timelines, technology, security, and intellectual property.
Should we build native apps or cross-platform (Flutter/React Native)?
For 95% of modern consumer and business applications, cross-platform with Flutter or React Native is the superior choice. You write code once, cut development and maintenance costs in half, release features simultaneously to iOS and Android, and still achieve native 60fps performance and access to all device sensors.
Do you assist with Apple App Store and Google Play approval?
Yes! App review guidelines can be notoriously strict around privacy, user data, and payments. We handle the entire submission, configure privacy nutrition labels, set up internal testing tracks, and guide the app through to public approval.
Can the mobile app work offline without cellular data?
Yes. We specialize in offline-first architectures. The app stores data locally in an encrypted SQLite database on the user's phone, allowing them to browse and create data offline. When internet connection returns, the app automatically syncs the differences in the background.
How do push notifications work?
We set up automated push notifications through Firebase Cloud Messaging (FCM) and Apple Push Notification service (APNs). You can send automated alerts for order updates, appointment reminders, new chat messages, and marketing announcements.
