FAQ

Before a project starts

What does a mobile app and game studio do?

A mobile app and game studio designs, builds, tests and launches apps and games for iOS and Android. At Vasoo that covers product strategy, UX and UI design, native or cross-platform engineering, backend and API work, AI integration, App Store and Google Play submission, and post-launch growth such as App Store optimisation and subscription tuning.

Do you develop mobile games?

Yes. Vasoo is a mobile app and game studio. We develop games for iOS and Android from first prototype to launch: core loop and level design, art direction, engineering, monetisation through ads and in-app purchases, Game Center and Google Play Games integration, and store launch. We publish our own games too: idle tycoon, puzzle, arcade, runner and trivia titles are live in the App Store.

How much does it cost to create a mobile app?

Cost depends on scope, platforms and integrations far more than on any single technology choice. A focused first version with a handful of core screens sits at the lower end; apps with real-time features, payments, AI or complex backends sit higher. We scope every project in a Discover phase and give a written, itemised proposal before any build starts.

How long does it take to build an app?

A focused first version is typically a matter of months, not weeks or years. The timeline is set in Discover once scope, platforms and integrations are known, and you see a working build on your phone at the end of every sprint.

Should we build native or cross-platform?

Native (SwiftUI, Kotlin) when the app relies on device features, performance or platform-specific UI. Cross-platform (React Native, Flutter) when one team needs to ship the same product to both stores quickly. We recommend based on your roadmap, and we build both.

Do you work with startups as well as established companies?

Yes. Startups usually come to us for an MVP or a first version they can raise on or sell. Established companies come for a new product line, a rebuild of an ageing app, or a dedicated team to extend an existing one.

Who owns the code and the App Store listing?

You do. Code lives in your repositories, apps are published under your developer accounts, and every credential and asset is handed over. We can operate the accounts on your behalf if you prefer.

Can you add AI features to an existing app?

Yes. We integrate generation, search and assistant features into existing iOS, Android and cross-platform apps, with attention to inference cost, latency, privacy and content moderation. Our own AI apps are live in the App Store.

Mobile app and game development for startups and established companies

Vasoo is a mobile app and game development studio. We take apps and games from idea to the App Store and Google Play: product strategy, UX and UI design, native iOS development in Swift and SwiftUI, native Android development in Kotlin and Jetpack Compose, cross-platform development with React Native and Flutter, and game development in Unity.

We build AI features as product features, with inference cost, latency, privacy and moderation handled. After launch we run App Store optimisation, localisation, subscription and ad monetisation testing. We develop and publish our own apps and games, which is where that experience comes from.
