- Cross-platform compatibility using frameworks like React Native or Flutter
- Native container wrapping web content for app store distribution
- WebView components displaying HTML5 content within native shells
- Access to device features through native bridge interfaces
| Application Type | Installation Required | Device Feature Access | Performance Level | Development Cost |
|---|---|---|---|---|
| Native | Yes | Full | High | High |
| Web-Based | No | Limited | Medium | Low |
| Hybrid | Yes | Moderate | Medium | Medium |
