FAQ

App Development: common questions

Do you build for both iOS and Android?

Yes. We build cross-platform apps with frameworks such as React Native or Flutter where they fit, and native Swift or Kotlin where performance or platform features require it.

How long does it take to build an app?

A focused MVP typically takes weeks rather than months after discovery. Timelines depend on scope, integrations and compliance needs, which we confirm in a fixed discovery phase.

Can you add AI features to an existing app?

Yes. We add AI assistants, smart search, document understanding and personalisation to existing apps via secure back-end services.
