Native & cross-platform
Mobile App Development
Android and iOS applications built from an agreed brief, on whichever platform approach suits the job, and tested on real devices. Aarna Info treats the updates after launch as part of the same piece of work rather than a fresh negotiation.
Capabilities
Seven Parts of a Mobile Build
From the platform decision through to the release that ships long after launch.
Android Development
Kotlin on the Android SDK. Jetpack for navigation, lifecycle, background work and storage. Minimum API level set from the devices your users hold, which across most of India is older than the one on the desk. Keystore, App Bundle and staged rollout included, not quoted separately.
iOS Development
Swift in Xcode. SwiftUI or UIKit according to what the interface demands and how far back support has to reach. Apple conventions followed, because iOS users notice an Android layout wearing an iOS skin. Certificates, provisioning and review submission handled here.
Cross-Platform Development
Flutter or React Native where one codebase across both stores is the better bargain. The trade is real and gets settled before any code: less to maintain, further from the hardware, native modules required either way. Never chosen to shrink a quotation.
API Integration
Authentication, pagination, retries, and the question that decides whether an app feels solid: what the screen does when the connection dies mid-request. Responses parse into typed models, so a server change breaks a build rather than a user session.
Firebase / Backend Integration
Firebase where a managed backend genuinely removes work — sign-in, Firestore, storage, push, crash reporting. Outgrowing it means moving to a Node.js service with its own database behind one documented interface, so the app sees almost nothing of the migration.
Performance
Cold start, frame drops, memory, network calls, battery. Profiled on physical devices, not an emulator on a fast machine. The fixes are routine: work off the main thread, images sized correctly, sensible caching, a smaller download — which matters when storage is permanently full.
Releases & Upkeep
A published app decays if left alone. New OS versions, store policy changes, retired APIs, vulnerable dependencies. Keeping it compiling and shipping, acting on crash reports, and batching improvements into planned releases is continuing work.
Development workflow
How a Mobile Project Runs
The same four as every other engagement. On mobile: fix the platform and the requirement, design screens and structure, build against physical devices, then store review and the long tail after it.
- 01
Specify
Conversations with whoever does the work now, turned into a written description of what gets built and what does not. You approve it before anything else begins.
- 02
Design
Screens, data model and structure decided before code. Then the whole thing is cut into milestones small enough to be either done or not done.
- 03
Build and Test
Delivered in reviewable increments. Each one is checked on the normal path, on bad input, on a slow connection and on hardware several years old.
- 04
Ship and Support
Released, with the repository, the accounts and the notes that explain the decisions. We remain available for fixes, releases and the next piece of work.
Technology
What Mobile Needs
Selected per project. These are the tools mobile work normally requires, plus the services that typically sit behind an app.
Native and cross-platform
Kotlin and Java with the Android SDK and Jetpack on Android, Swift and SwiftUI on iOS, and Flutter or React Native when one shared codebase is the better fit for the requirement.
- Kotlin
- Java
- Android SDK
- Jetpack
- Swift
- SwiftUI
- Flutter
- React Native
Backend and integration
Most applications need something behind them. We build REST interfaces on Node.js and use Firebase for authentication, data and file storage where a managed backend keeps the project simpler to run.
- Node.js
- REST APIs
- Firebase

Have an App to Build?
What it does, which stores, what it connects to. Questions come back first; a costed plan follows once those are answered.
