List what the app needs from the device
Ordinary account screens differ from demanding camera, Bluetooth, location or background-processing requirements. Identify the platforms and devices you actually need to support. Build a small proof of the highest-risk feature before selecting an approach solely because it promises shared code.
Prototype the hardest device behaviour first
An example field-service app must scan labels, keep photos offline and upload work after connectivity returns. A polished login screen will not reveal whether the chosen approach handles these requirements.
| Prototype task | What to measure on target devices |
|---|---|
| Scan damaged labels in poor light | Successful reads, retry behaviour and camera permissions |
| Capture work with no network | Local persistence after the app is closed or the device restarts |
| Reconnect after conflicting edits | Conflict handling, upload resumption and duplicate prevention |
Compare the entire delivery effort
Shared code can reduce duplication in some areas, while platform-specific behaviour still needs design and testing. Native implementations may require separate work across platforms. Compare backend development, device testing, release management and specialist availability as well as the number of codebases.
Plan for the next platform update
The choice continues to matter after launch. Assign responsibility for framework upgrades, device regressions and store requirements. Check how a critical dependency is maintained and what happens if it no longer supports your use case. A suitable approach is one your team can operate, not just demonstrate once.
Before you proceed
- Prototype the most demanding device feature.
- Compare delivery and maintenance on both platforms.
- Agree target devices and a release-support plan.
