Mobile App Development FAQs
Should I build a native or cross-platform app?+
For most business apps, cross-platform React Native is faster and more cost-effective because one codebase runs on iOS and Android. Native development makes sense for apps that need heavy graphics, advanced device features, or maximum performance.
How much does it cost to build a mobile app?+
Cost depends on the number of screens, features, integrations, and backend complexity. We scope your app in a free consultation and provide a fixed or milestone-based quote.
How long does mobile app development take?+
A focused first version typically takes a few months, including design, development, testing, and store submission. Larger apps are delivered in phases so you can launch earlier.
Do you publish the app to the App Store and Google Play?+
Yes. We prepare store listings, handle submission and review requirements, and manage releases, under your own developer accounts so you keep full ownership.
Can you add AI features to my app?+
Yes. We add AI assistants, smart search, recommendations, document scanning, and image recognition, connected to secure backend services so API keys and data stay protected.
