Cross-Platform App Development

A mobile app should extend a useful product workflow to the places and moments where customers need it. Flex Engineers plans and builds React Native applications that can connect with an existing web product, backend, and account model.

Decide what belongs on mobile

Not every web feature needs a mobile counterpart. Start with the tasks users need to complete on a phone, the device capabilities involved, and how the mobile experience should interact with the existing product.

  • Prioritize mobile user journeys and device-specific needs
  • Plan navigation, authentication, and account behavior
  • Identify backend APIs, data, and web-product dependencies

Share product foundations where it fits

A cross-platform approach can share application code, while still requiring careful work on platform behavior, responsive layouts, permissions, and device testing.

  • React Native application development
  • Integration with shared APIs, accounts, and product data
  • Testing for relevant iOS and Android devices and workflows

Prepare for release and maintenance

Mobile delivery includes release planning as well as implementation. Store requirements, review processes, signing, and ongoing platform updates should be considered as part of the project scope.

  • Agree on iOS and Android release requirements
  • Test core flows on target devices
  • Plan maintenance for app and platform changes

COMMON QUESTIONS

Cross-Platform App Development questions

Can one React Native app support iOS and Android?

React Native lets teams build cross-platform applications with shared code, but platform-specific behavior and testing still need to be considered for each release.

Can the mobile app use my existing backend?

Yes, if the existing APIs and authentication model meet the mobile product's requirements. The integration approach can be confirmed after reviewing the current system.

Do you have a published mobile app case study?

We do not yet have a verified published React Native app case study to share. The related examples above show web-app and backend work that can inform a mobile product's shared APIs, accounts, and workflows.
