Technologies
Mobile app development technologies, languages and frameworks we use
These are the mobile app development technologies we build with, grouped by the decision they answer: which language, which UI framework, which backend, which cloud and which integrations. Each page explains when we choose a technology, when we do not, and what it means for hiring and maintenance after launch.
We pick the stack from your requirements, not from a house favourite. If you want to see how technology choices fit into delivery, start with our app development services or the way we work.
- Native and cross-platform
- Supported versions only
- Stack chosen per project
- Code in your own repository
Languages and UI frameworks
The client side: what your users install. Native gives the deepest platform access; cross-platform shares one codebase across iOS and Android.
Swift
Apple’s preferred language. The Swift 6 language mode turns data races into compile errors, and Swift interoperates with older Objective-C code.
Kotlin
Android has been Kotlin-first since 2019. Coroutines for async work, and Kotlin Multiplatform for sharing logic with iOS.
SwiftUI
Apple’s declarative UI framework, our default for new iOS screens, with UIKit where it still earns its place.
Jetpack Compose
Android’s recommended modern UI toolkit. New screens in Compose; Views migrated screen by screen.
Flutter
One Dart codebase for iOS and Android with a custom-drawn UI. Impeller is the default renderer on iOS and on Android API 29+.
React Native
JavaScript or TypeScript with native UI components. The New Architecture has been the default since version 0.76.
More languages we work with
Each has its own page, and we use all of them on live projects:
- Java app development: maintaining and migrating older Android apps toward Kotlin.
- Dart app development: the language behind Flutter.
- JavaScript and TypeScript app development: React Native apps, React web dashboards and Node.js backends, with TypeScript in strict mode by default.
Not sure whether native or cross-platform suits your app? Our native vs cross-platform guide and Flutter vs React Native comparison set out the trade-offs.
Backend technologies for mobile apps
The server side: APIs, data, admin tools and background jobs. See our mobile app backend development service for architecture and hosting.
Node.js
Real-time APIs, chat and tracking, many integrations, and a shared TypeScript stack. Production runs LTS releases only.
Laravel
PHP framework for workflow-heavy apps: APIs plus admin panels from one codebase, on a yearly release cycle.
Firebase
Firestore, Auth, Cloud Messaging and Crashlytics for fast MVPs, with cost control and an exit plan.
Cloud, data, AI and specialist technologies
We also build with the following, each covered on its own page; ask us about any of them on a scoping call.
Backend and cloud
- Python and Django app development for data-heavy backends
- Supabase app development for Postgres-based backends that can be self-hosted
- .NET app development for teams with a Microsoft stack
- AWS, Google Cloud app development and Microsoft Azure app development, always in your own account
- Mobile app database choices for offline-first apps (local storage and sync)
AI, AR and games
- Core ML for on-device AI on Apple devices
- TensorFlow Lite (now LiteRT) and ML Kit for on-device ML on Android and iOS
- ARKit and ARCore for augmented reality
- Unity app development for games and 3D experiences
For AI features specifically, see our AI app development service.
Integrations and delivery tooling
The parts that touch money, identity and release pipelines. Most store rejections and compliance problems start here.
Payment gateway integration
Stripe, PayPal, Adyen, Apple Pay and Google Pay, in-app purchase rules, PCI scope reduction, and JazzCash, Easypaisa and Raast for Pakistan.
Other integrations and delivery tooling
Google Maps and location services, push notifications, in-app purchases and subscriptions, authentication and SSO, and mobile CI/CD with fastlane, GitHub Actions and Codemagic.

Choosing mobile app development technologies: a quick decision table
A starting point, not a rule. Most projects mix these; we explain the choice in writing after discovery.
| If your app needs… | We usually start with | Why |
|---|---|---|
| iOS first, deep Apple integration | Swift + SwiftUI | Direct access to new Apple APIs; strong performance |
| Android first, device or hardware features | Kotlin + Jetpack Compose | Platform’s own direction; full hardware access |
| iOS and Android at launch on one budget | Flutter or React Native | One codebase; roughly half the cost of two native builds per Clutch |
| MVP live in weeks with realtime data | Firebase | Auth, database and push already managed |
| Real-time features or a shared TypeScript stack | Node.js | Handles many open connections efficiently |
| Heavy admin panels and business workflows | Laravel | Strong conventions; API and admin in one codebase |
| Physical goods checkout | Stripe or a local gateway + Apple Pay / Google Pay | Store rules forbid IAP for physical goods |
| Digital content or subscriptions | StoreKit and Play Billing | Store rules require in-app purchase |
How we choose, and what you own afterwards
Stack decisions are made in discovery, which runs for one to two weeks. We weigh your markets (StatCounter puts iOS at 53.6% of US mobile share in September 2026, while Android holds 69.2% worldwide), the features that need deep platform access, your budget, your launch date, and who will maintain the app in three years. A fixed price follows discovery.
Whatever we choose, the code lives in your repository from day one and cloud accounts are in your name. If you would rather add engineers to your own team, you can hire mobile app developers for a specific stack, with a two-week trial.
Mobile app development technologies: frequently asked questions
Which technology is best for building a mobile app?
There is no single best one. Swift and Kotlin give the deepest platform access, Flutter and React Native share one codebase across iOS and Android, and the backend depends on whether your app is real-time, admin-heavy or an MVP. We recommend a stack after discovery based on your markets, features, budget and maintenance plans.
Do you build native or cross-platform apps?
Both. We build native apps in Swift and Kotlin and cross-platform apps in Flutter and React Native. Cross-platform suits most apps with standard screens and a tight budget for both platforms. Native suits apps with heavy platform integration, demanding performance, or a single dominant platform. We explain the trade-off in writing for your case.
Can you work with our existing stack?
Usually, yes. We take over and extend existing Swift, Objective-C, Kotlin, Java, Flutter, React Native, Node.js, Laravel and Firebase codebases. We start with an audit of code quality, dependency versions and test coverage, so you know the state of the code and the risks before committing to new features.
Which backend do you recommend for a mobile app?
Firebase for fast MVPs with realtime data and simple rules; Node.js for real-time features, many integrations or a shared TypeScript stack; Laravel for workflow-heavy apps with rich admin panels. Many products combine them, for example Firebase Auth and push with a Laravel or Node.js API. We decide based on your data, team and growth plans.
How do you keep technology choices from becoming outdated?
We start on supported versions only, such as current Swift and Kotlin toolchains, Node.js LTS releases and supported Laravel majors, and document an upgrade plan for each. Maintenance plans follow the yearly Apple and Google release cycles, so SDK, target API and framework upgrades happen on schedule rather than in a rush before a store deadline.
