Mobile App Development: questions, answered
Should I build a native app or a cross-platform app?
For most business apps, cross-platform (Flutter or React Native) gives you Android and iOS at a lower cost. Native is better for heavy graphics or deep device integration. We recommend the right option after understanding your requirements.
Do you publish the app on Google Play and the App Store?
Yes. We prepare store listings, screenshots and privacy details and handle the submission and review process for both stores.
How much does a mobile app cost?
Cost depends on features, platforms and integrations. Share your idea with us and we will send a detailed proposal with scope, timeline and a fixed quote.
Will I own the source code?
Yes. Once the project is complete and paid for, you receive full ownership of the source code and store accounts.
