Hybrid Web Views vs. ZAVA Native-Grade Mobile Architecture
Why enterprise brands demand true 60fps native performance over cheap web wrappers.
| Mobile Metric | Hybrid Web View (Ionic / Cordova) | ZAVA Native React Native / Flutter |
|---|---|---|
| UI Rendering & Frame Rate | ✖ Jittery 24-30 FPS (Web View DOM) | ✔ 60 FPS Fluid Native Thread Render |
| Offline Performance | ✖ Fails Offline Requires active internet | ✔ Offline-First WatermelonDB Sync |
| App Startup Speed | ✖ Slow 4-6s Splash Screen Load | ✔ < 1.5s Instant Cold Launch |
| Hardware & Sensor Access | ✖ Buggy Plugins Limited Bridges | ✔ Direct Native Swift/Kotlin C++ Bridges |
| Bugfix Deployment | ✖ Wait 48h App Store Review Queue | ✔ Instant OTA EAS Over-The-Air Update |

Do you assist with Apple App Store and Google Play submissions?
How do Over-The-Air (OTA) updates work?
Trusted by Builders
They shipped our iOS and Android app with 95.4% shared code, and the animations hold a true 60fps. We cut our mobile roadmap in half.
The offline-first sync with WatermelonDB means our field teams work in dead zones without missing a beat, and OTA updates ship in minutes.
Biometric security and full HIG and Material compliance out of the box. Both stores approved our app on the first submission.
