FAQ
Cross-Platform Apps (Flutter & React Native) questions
Not answered here? Ask us directly.
React Native vs. Flutter: which should we choose?
React Native is ideal if your team already knows JavaScript/React and wants deep native platform integration. Flutter is exceptional for brand-heavy, custom visual designs with complex animations. We recommend the right fit after scoping.
Does a cross-platform app look and feel native to users?
Yes. Both Flutter and React Native compile to native machine code and render native UI widgets. The vast majority of users cannot distinguish them from pure native builds.
How much cost and time does a single codebase save?
A cross-platform build typically saves 40% to 50% in initial development cost and cuts ongoing maintenance hours in half, because bug fixes and new features ship once for both platforms.
Can you convert an existing web app into a mobile app?
Yes. We can leverage existing backend APIs and component logic to rapidly build cross-platform mobile apps that share data with your web application.
How much does WebMarv charge for cross platform mobile app development?
WebMarv's cross platform mobile app development work is part of Software Engineering, which starts from ₹1L. The final price depends on scope and is agreed in writing after a free audit.
