Once you have chosen the platforms and product workflow, compare React Native, Flutter and native development against verifiable requirements. A generic matrix of percentages cannot predict your app's cost or performance. Document the chosen approach and the reasons the alternatives were rejected.
React Native
Assess the fit with the team's React and JavaScript/TypeScript experience, the libraries needed and the interface requirements. Web experience does not remove the need to learn mobile behavior. The official documentation on platform-specific code explains how to separate implementations where iOS and Android have different needs.
Flutter
Assess Dart experience, visual requirements, plugin compatibility and build and distribution processes. For device features, check the implementations available on each platform. The documentation on platform channels explains the connection between Flutter and platform code.
Swift and Kotlin
Assess this option when the product focuses on one platform, when a native team is available or when deep integration with the operating system justifies the approach. For two platforms, estimate implementation and testing for each, along with the components that can remain shared in the backend.
Verification matrix
- Integrations: required SDKs, supported versions, licenses and the person responsible for maintenance.
- Devices: hardware features, permissions, background behavior and connectivity.
- Interface: accessibility, navigation and platform-specific behavior.
- Operation: testing, monitoring, updates and release.
- Team: demonstrable experience, documentation and the ability to hand over.
How do you verify performance?
Choose the critical workflow, devices and network conditions. Measure startup, interaction response and the resources relevant to the product. Compare the same task using the same data and criteria. Do not turn the result of a trial into a universal performance percentage.
What should you request in the final recommendation?
A written decision, remaining risks, trials performed and the impact on maintenance. Include the effort required if a library becomes unsuitable or a component needs to be replaced.
For the business decision, see native versus cross-platform (in Romanian). For requirements and delivery, explore our mobile development service. The Jerry's Pizza project provides a real example of workflows without serving as a benchmark between frameworks.
