FAQs

Frequently Asked Questions About Android App Development

What technology stack do you use for Android apps?

We build native Android apps with Kotlin (and Java where needed), following modern architecture patterns like MVVM and Jetpack Compose. For teams that need shared code, we also build with Flutter or React Native — whichever fits your product best.

How long does it take to build an Android app?

A well-scoped MVP typically takes 8–16 weeks. Larger platforms with complex backends, payments, or integrations take longer. We give you a detailed timeline during discovery and keep you updated every sprint.

Can you help us publish to the Google Play Store?

Yes. We prepare store listings, app icons, and privacy disclosures, and guide you through Play Console review — including policy compliance, which is the most common cause of rejection.

Do you provide maintenance after launch?

We offer ongoing support plans covering OS updates, crash fixes, performance monitoring, and new features, so your app stays current and stable as Android evolves.
