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. Nimtree Infotech treats the updates after launch as part of the same piece of work rather than a fresh negotiation.
Capabilities
What the Work Covers
Everything from the first argument about which platform, through to the update that goes out long after launch.
Android Development
Kotlin on the Android SDK, Jetpack for navigation, lifecycle, background work and local storage. The minimum API level is argued from what your users carry rather than what is convenient to build against — in most of India that means older and slower. Keystore, App Bundle and staged rollout are part of the job.
iOS Development
Swift in Xcode, with SwiftUI or UIKit chosen on what the screens have to do and how far back support must reach. iOS users notice when an app does not behave like an iOS app, so it follows Apple’s conventions rather than wearing an Android layout. Certificates, provisioning and review submission are handled here.
Cross-Platform Development
Flutter or React Native, where one codebase for both stores is honestly the better bargain. That is a real trade and it gets discussed before anything is written: less to maintain against being further from the hardware, and native modules needed on either route. It will not be chosen to make a quotation look smaller.
API Integration
Joining the app to everything it relies on — authentication, pagination, retries, and the question worth more thought than it usually gets: what the screen shows when the connection drops mid-request. Responses parse into typed models, so a server change breaks a build rather than a customer’s evening.
Firebase / Backend Integration
Firebase where a managed backend genuinely removes work: sign-in, Firestore, storage, push, crash reporting. When a product grows past it, the move onto a Node.js service with its own database happens behind one documented interface, so the app barely notices and the migration stays our difficulty.
Performance
Measured rather than guessed: cold start, frame drops, memory, network traffic and battery, profiled on real devices instead of an emulator on a fast machine. The remedies are unglamorous — work off the main thread, correctly sized images, sensible caching, and a smaller download, which matters on a phone that is permanently short of storage.
Releases & Upkeep
Left alone, an app decays. A new OS lands, a store rule changes, an API is withdrawn, a dependency turns out to be vulnerable. Keeping the project building and releasing, acting on what crash reports say, and gathering improvements into planned updates is ongoing work rather than an afterthought.
Development workflow
How a Mobile Project Runs
The same four stages as any other job. For mobile that means agreeing platform and requirement, planning screens and structure, building against real handsets, and then store review and everything after it.
- 01
Understand
Time with the people who do the task now, writing down what actually happens rather than what the org chart says happens. The gap between those two is where most of the surprises live.
- 02
Write It Down
Screens, data and structure settled on paper, then cut into milestones small enough that whether one is finished is a matter of fact rather than opinion.
- 03
Build
Delivered in pieces you can look at, tested as they go — the ordinary path first, then the awkward inputs, a weak connection and a phone that is several years old.
- 04
Hand Over
Published, with the repository, the credentials and the notes that explain the decisions. We stay reachable for corrections, releases and whatever the next thing turns out to be.
Technology
What Mobile Work Uses
Chosen per project, not out of habit. These are what a mobile build normally calls for, together with the services that usually sit behind one.
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.

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.

Thinking About an App?
What it has to do, which stores it must reach, what it needs to talk to. The difficult questions come back first; a plan you can budget against comes after that.
