Our Mobile App Development Services Include:
- Flutter Cross-Platform Development
We use Flutter, Google’s most powerful cross-platform framework, to build apps that offer native-like performance on both Android and iOS. This means faster development, smoother animations, and consistent user experiences — all with reduced cost and maintenance.

Frequently Asked Questions
Do you build in Flutter or native code?
Flutter for most projects, because one codebase serving both platforms halves the build and long-term maintenance cost. We build native when a feature genuinely requires it, and we explain the trade-off before you decide.
Who owns the app code and the App Store listings?
You do. Code is handed over in documented repositories, and the App Store and Google Play listings are published under your own developer accounts, so the app remains yours regardless of who maintains it later.
How do you run app projects across time zones?
We overlap working hours for calls and launches, install milestone builds on your device so you can test as we go, and send written daily updates so progress is visible without a meeting.
How much does a mobile app cost in Sri Lanka?
Our custom mobile app development services start from LKR 120,000. The price varies based on features, complexity, and whether it's for iOS, Android, or both.
How long does it take to build a mobile app?
A simple app can take 1-3 weeks, while a more complex app with a backend server, user accounts, and payments can take 4-10 weeks or more.
Do you build for both iOS and Android?
Yes. We are experts in both native development (Swift/Kotlin) and cross-platform development (React Native, Flutter) to build apps for both iOS and Android efficiently.
Can you build a mobile app for my business in Jaffna?
Absolutely. We are a leading mobile app development company serving Jaffna, providing high-quality, fast, and user-friendly apps for local businesses.
Will my app be published on the App Store and Play Store?
Yes, our service includes preparing and submitting your app to both the Apple App Store and Google Play Store, ensuring it meets all guidelines.

Mobile app development for international clients
We work with clients across the UK, Europe, the UAE, Australia and North America, delivering senior mobile engineering at a fraction of local agency rates without the quality trade-off that usually implies.
Most projects are built in Flutter so a single codebase ships to both the App Store and Google Play, cutting build and maintenance cost roughly in half. Where a feature genuinely demands it — heavy device integration, advanced graphics — we build native instead and tell you why.
You own everything. Code is delivered in documented repositories under your account, along with the backend, APIs and admin panel, so you can move the project in-house or to another team whenever you choose.
Remote delivery runs on a written scope and fixed price agreed before work starts, a clickable prototype you sign off, milestone builds installed on your own device for testing, and written daily updates throughout.
