Mobile app development in Sri Lanka
Zeylix builds mobile apps for iOS and Android from our studio in Colombo, Sri Lanka. We use Flutter to ship one high-quality codebase to both platforms, which keeps your budget focused on features instead of maintaining two separate apps.
We handle the whole product: the app itself, the back end and APIs it talks to, the admin tools your team uses to run it, and the release process through the App Store and Google Play.
What we deliver
Cross-platform apps with Flutter
One codebase for iOS and Android with native performance, platform-appropriate design and access to device features like the camera, location and notifications.
Customer-facing consumer apps
Ordering, booking, loyalty and account apps designed for real-world use: quick to load, clear to navigate and dependable on patchy connections.
Field and business apps
Apps for sales teams, delivery staff and technicians, with offline support and syncing back to your central system when the connection returns.
Back ends and admin panels
Secure APIs, authentication, push notifications and the web dashboards your staff need to manage users, content and orders.
App store release and maintenance
Store listings, review submissions, crash monitoring, OS-version updates and ongoing improvements after launch.

How we work
- 01
Discovery
We start with a conversation, not a pitch. You walk us through what you're building and where it's stuck; we ask the hard questions and tell you honestly whether Zeylix is the right fit.
- 02
Scope & Feasibility
We pressure-test the idea against real constraints — architecture, timeline, budget — and come back with a practical plan instead of a vague estimate.
- 03
Trial Sprint
Before any long commitment, we run a paid trial sprint or POC. You see how we actually ship; we learn your product and your standards. Low risk, real output.
- 04
Long-Term Build
Once the trial proves the fit, we move into the full engagement — the same team you met on day one, weekly reporting, and a roadmap shaped by what we learned in the trial.
Frequently asked questions
- Do you build native or cross-platform apps?
- We primarily build with Flutter, which compiles to native code for both iOS and Android from a single codebase. For most products that means faster delivery and lower maintenance cost with no visible compromise for users.
- Will you publish the app to the App Store and Google Play?
- Yes. We prepare the store listings, handle submission and review, and set up the release process so future updates ship smoothly. The developer accounts stay in your company’s name.
- Can the app work offline?
- Yes, where the product needs it. We design local storage and background sync so staff and customers can keep working without a connection.
- Do you also build the back end?
- Yes. Most apps need an API, a database and an admin panel, and we build and host those alongside the app so everything is designed to work together.
