FAQ

Common questions

How much does it cost to develop a mobile app in Sri Lanka?

Cost depends on the features, screens, integrations and whether you need a backend and admin panel. We send a fixed-scope quotation after a discovery call, and can start with a smaller first version.

Do you build for both iOS and Android?

Yes. We build with Flutter, so one codebase produces both an iOS and an Android app, which reduces cost and keeps both versions in sync.

How long does it take to build a mobile app?

A focused first version typically takes a few months, depending on scope. We work in short cycles with regular demos so you can review progress.

Will you publish the app on the App Store and Google Play?

Yes. We prepare the builds and guide you through submission, review and release on both stores.

Can you add a mobile app to my existing website or system?

Yes. We can connect a new app to your existing backend through APIs, or build the backend as part of the project.
