Mobile App Development
Custom iOS and Android apps engineered for performance, security and long-term growth — from first prototype to store launch.
What is mobile app development?
Mobile app development is designing and building applications that run on smartphones and tablets, either natively for each platform or with a cross-platform framework. It covers interface design, device features, backend integration, testing and submission to the Apple App Store and Google Play.
A mobile app is the most direct channel you own — it sits on the home screen with push notifications and offline access. Whether that advantage is realised depends on architecture choices made before the first screen is drawn.
Why do mobile apps need the right platform strategy?
Mobile apps put your product in your customers' pockets — with push notifications, offline access and device capabilities the web alone cannot match. But a great app needs more than a UI: it needs solid architecture, secure APIs and a release process that survives app store review.
Nexoraft designs and builds custom mobile applications for iOS and Android. We choose native or cross-platform based on your performance needs, budget and roadmap — then take you through design, development, testing and store submission. See platform-specific pages for iOS and Android, or pair with API development for your backend.

How much does mobile app development cost?
There is no fixed price for a mobile app — the budget follows how many platforms you target and how much sits behind the interface. The factors below decide most of the cost:
-
Platform count — One platform (iOS or Android) is the cheapest start. Building both doubles much of the UI, testing and release work unless a shared codebase absorbs it.
-
Native vs cross-platform — Native Swift and Kotlin deliver maximum performance and platform depth; React Native or Flutter share one codebase across both stores for lower build cost.
-
Backend and API complexity — A simple content app with an existing API is quick; real-time data, payments, user accounts and admin systems add server-side work of their own.
-
Third-party SDKs — Payment gateways, maps, messaging, chat and analytics SDKs each need integration, licensing and review by the stores before they ship.
-
Store submission rounds — Rejection and resubmission cycles add days to weeks. Clean privacy labels, permissions and guidelines compliance keep the first launch on schedule.

Discovery & Strategy
We define users, platforms, core features and the right native vs cross-platform approach.
UX & Prototype
Wireframes and interactive prototypes validate flows before a line of code is written.
Build & Test
Iterative development with device testing, QA and performance tuning each sprint.
Launch & Grow
Store submission, monitoring and continuous feature releases after launch.
Why this technology stack?
The platform choice is the first decision in a mobile project — it sets performance, cost and how fast you reach both stores.
Swift (iOS native)
The best fit when iOS is your priority: full access to platform APIs, strong performance and the polished feel Apple users expect.
Kotlin (Android native)
Modern, concise and officially backed by Google — ideal when you need deep Android integration and reliable support across device types.
React Native
One JavaScript codebase ships to both stores with near-native results, and your web team can contribute without learning two mobile languages.
Flutter
A single compiled codebase with pixel-consistent UI on both platforms — fast to iterate when design consistency matters more than platform-specific depth.
