It depends on the number of screens, integrations (payments, maps, IoT, internal systems) and whether the app is for iOS, Android or both. At QKStudio we quote each project individually after a discovery call and deliver a proposal with scope, phases and a fixed budget per phase. An MVP is usually the most efficient way to validate the idea before investing in every feature.

A typical project takes between 6 and 16 weeks, with partial deliveries every two weeks. An MVP with essential features falls at the short end; an app with its own backend, an admin panel and integrations, at the long end. It includes discovery, UX/UI design, development, testing and publishing on the App Store and Google Play.

For most projects we recommend React Native: a single codebase for iOS and Android, lower cost and shorter timelines, with near-native performance. We choose native development (Swift or Kotlin) when the app makes heavy use of hardware, Bluetooth, IoT or complex animations. We decide together during the discovery phase.

Because fixing a problem in a prototype costs far less than fixing it in code. Before developing, we validate flows and screens with real users through clickable prototypes. That way we reduce rework, improve retention and reach launch with an app that people understand from the first use.

Yes. We handle developer accounts, store listings, screenshots, policy review and publishing. As a Google Partner Premier, we can also plan the launch campaign with Google App Campaigns and measure installs and usage with GA4 and Firebase.

We offer support and evolution plans: operating system updates, bug fixes, monitoring, new features and continuous improvement based on usage data. The app is yours: we hand over the source code and documentation.
