Questions
Mobile App Development FAQs
Should I build a native app or a cross-platform app?
Cross-platform (React Native or Flutter) fits most products: one codebase, faster shipping, lower cost. Native Swift or Kotlin is worth it when you need deep platform integration or maximum performance. DevionX builds both and will recommend based on your requirements, not our preference.
Do you handle App Store and Google Play submission?
Yes. We prepare store listings, manage certificates and provisioning, handle review feedback and set up phased rollouts. Our partner FieldFlicks has shipped three app versions to production with us.
How much does mobile app development cost?
It depends on platforms, feature depth and backend complexity. Every DevionX engagement starts with a discovery phase that produces a fixed milestone-based quote, so you know the investment before development begins.
Do you provide support after launch?
Yes. DevionX offers post-launch support and maintenance plans covering monitoring, fixes, enhancements and scaling. Several partners have continued working with us for years after their first release.
