Mobile applications
We build mobile applications that remain reliable in the hands of users on the move. From public store apps on iOS and Android to enterprise field tooling, we deliver high-performance applications designed to work under weak network signals, integrate seamlessly with hardware features, and ship with crash reporting and analytics from day one.
Service Summary
Bilingual iOS and Android apps utilizing shared codebases for efficiency, native paths where performance counts, with offline syncing built-in.
Problems Solved
Mobile apps often fail due to poor offline signal handling, high battery drain, memory leaks, and complicated store deployment processes.
Who it is for
This service is built for product teams launching consumer services, operational businesses requiring a dedicated tool for field staff (such as logistics coordinators or site inspectors), and brands establishing loyalty programs. We help you choose the right approach - cross-platform or native - depending on your technical requirements and long-term maintenance resources.
Scope of work
Our mobile development process covers the entire app lifecycle, from device compatibility design to successful publishing and post-launch maintenance.
- Cross-Platform and Native Builds: We build using React Native or Flutter to target both iOS and Android from a single codebase, saving development cost. For high-performance graphics, complex Bluetooth tasks, or system-level services, we write native Swift or Kotlin code.
- Offline-First Synchronization: We implement local storage layers (using SQLite or WatermelonDB) to let the app work without an internet connection. When the device goes online, the app runs structured sync cycles that resolve conflicts without losing user data.
- Hardware and System Integration: We integrate camera functions for barcode scanning, GPS tracking for geolocation, push notifications for user alerts, and biometrics (Face ID/Touch ID) for secure and fast login experiences.
- Automated Store Publishing Pipelines: We set up automated build pipelines using Fastlane to sign, package, and upload builds directly to TestFlight and Google Play Console. This simplifies beta testing and ensures that release day runs smoothly.
Our Engineering Approach
We build native-quality apps with cross-platform frameworks, write clean native bridges when hardware access requires, and deploy using automated Fastlane pipelines.
Core stack
We develop cross-platform apps using React Native or Flutter with TypeScript/Dart. For native elements, we use Swift (iOS) and Kotlin (Android). We implement local persistence using SQLite or WatermelonDB and secure communications via HTTPS/WSS. Stability metrics are tracked using Firebase Crashlytics, and build distribution is automated with Fastlane.
The process
We follow a structured mobile development workflow to deliver stable, high-performance apps that pass store reviews.
Typical timeline
A typical custom mobile application takes 12 to 20 weeks to go from initial concept to store launch. Discovery takes 2 weeks, active development cycles take 8 to 14 weeks (including API integration), and the final store submission, regression testing, and review process takes 2 to 4 weeks.
Engagement models
We provide flexible engagement models depending on whether you require a full product team or targeted sprint delivery.

Frequently Asked Questions
Should we build native (Swift/Kotlin) or cross-platform (React Native/Flutter)?
For 90% of business applications, cross-platform (React Native or Flutter) is the best choice because it lets you target both iOS and Android from a single codebase, reducing initial cost and ongoing maintenance. We only recommend native Swift or Kotlin for apps that require high-performance rendering, complex 3D graphics, or advanced system integrations.
Who sets up and owns the App Store developer accounts?
You must set up and own the Apple and Google Developer accounts. We guide you through the enrollment process step-by-step. This ensures that you maintain full ownership of your app listing, distribution rights, and customer reviews. We only request developer access to sign and upload the builds.
How does the app behave when there is no internet connection?
We build our apps to be offline-friendly. The application stores vital database records, drafts, and media locally. Users can continue filling out forms, viewing cached information, and performing tasks. Once a connection is detected, the app automatically syncs the offline changes to the server in the background.
How do you test the app on different mobile phones?
We use a combination of simulated devices and physical hardware testing. We focus physical testing on a representative set of devices covering popular screen sizes, aspects, OS versions, and hardware specifications (low-end to high-end Android, and recent iPhone models) to verify real-world performance.
How do you handle application security and data privacy?
We secure the mobile app by storing sensitive data (such as login tokens) in the device's secure hardware enclave (iOS Keychain and Android Keystore). We enforce SSL pinning to prevent man-in-the-middle attacks, encrypt all data stored locally, and implement session timeouts to protect user access.
