How much does it cost to build a mobile app?
It depends on the platforms, number of features, integrations and design complexity. A focused MVP costs far less than a full-featured platform. After a short discovery call we send a clear, itemised proposal so you know exactly what you are paying for.
How long does it take to develop an app?
A focused MVP usually takes 8–12 weeks from kickoff to store launch. Larger apps with custom backends and integrations typically take 12–20 weeks. You get test builds on your phone throughout, not just at the end.
Should I build a native or a cross-platform app?
Cross-platform (Flutter or React Native) is usually faster and more cost-effective when you need both iOS and Android. Native (Swift or Kotlin) makes sense for apps that rely heavily on device hardware, complex animations or platform-specific features. We recommend the right fit for your product.
What is the difference between native, hybrid and web apps?
Native apps are built separately for each platform and offer the best performance. Cross-platform or hybrid apps share one codebase across iOS and Android. Progressive web apps run in the browser and can be installed without an app store, but have limited access to device features.
Will you publish the app to the App Store and Google Play?
Yes. We prepare store listings, screenshots and privacy details, handle submission and review, and publish the app under your own developer accounts so you stay in full control.
Do you provide support after the app launches?
Yes. Our care plans cover iOS and Android OS updates, crash monitoring, bug fixes, security patches and a monthly allowance of improvement hours, so your app keeps getting better.
