Turn your React web app into native iOS & Android in days, not months.
One single codebase, 100% native performance, zero compromises on the App Store.
Choose the Right Architecture for Your App
Deconstruct false good ideas: avoid the expensive full-native rewrite trap and the rejected URL wrapper shortcut.
Fast Launch
Capacitor + Responsive Optimization
The fastest and most cost-effective path to turn an existing responsive web app into native iOS & Android binaries.
Strengths
- Unbeatable time-to-market (delivery in 7 to 14 days)
- Single codebase: zero duplication of your business logic
- Essential native features: Push, Splash, Safe Areas, Biometrics
- Native Apple & Google Sign-In (Apple Guideline 4.8 compliant)
- Guaranteed Apple App Store & Google Play compliance
Risks & Limitations
- Keeps the existing web navigation UX (no native iOS bottom tabs)
Native Feel
Capacitor + Ionic UI / Tabs & Gestures
Combines Capacitor with native-grade UI patterns. Starting from $4,500, tailored to the volume of custom mobile UI components to adapt (alerts, popovers, select pickers, toasts, checkboxes...).
Strengths
- 100% native mobile feel (smooth 60fps view transitions)
- Native navigation patterns: bottom tab bar, native header & gestures
- Adapted UI components: native alerts, modal sheets, popovers, selects & toasts
- Native Apple & Google Sign-In with FaceID / TouchID biometric bridge
- Safe areas pixel-perfect optimization (Dynamic Island, notches)
- Subtle native haptic feedback on interactive controls
Full Native Rewrite
SwiftUI (iOS) + Jetpack Compose (Android)
Developing two completely separate codebases in Swift and Kotlin alongside your existing Web application. From $16,000 for a simple app, rapidly escalating with complexity.
Strengths
- Access to ultra-specialized hardware APIs (Metal 3D, ARKit)
Risks & Limitations
- Total rewrite required: 2 new distinct codebases
- Initial budget from €15k/€25k+ and delivery delays extended by months
- Every new feature must be coded 3 separate times
Simple URL Wrapper
Basic remote URL iframe / Webview
A cheap shell pointing directly to your website URL without local bundling or deep native integrations.
Strengths
- Low upfront quote
Risks & Limitations
- Guaranteed Apple rejection (Guideline 4.2 Minimum Functionality) if no native features are added
- Compliant under Guideline 4.2.2 ONLY when bundled with Push, Geolocation or Native Auth
- Network latency and white screens on slow connections
- No native push notifications, no biometric authentication
Complex Native Plumbing Handled Out of the Box
Turning a web app into a certified mobile binary requires dozens of native integrations. Here is what we implement:
Native Apple & Google Auth (Apple Guideline 4.8 Compliance)
- Native Sign in with Apple integration (@capacitor-community/apple-sign-in) mandatory under Guideline 4.8 whenever Google login is present
- Critical 1st-login profile capture: immediate storage of fullName & email (only returned once by Apple on the initial session)
- Apple Private Relay (Hide My Email) handling and server-side cryptographic JWT (identityToken) validation
- Native Google Sign-In with fluid One Tap UX without disruptive webview redirect popups
In-App Purchases & Subscriptions (RevenueCat / StoreKit 2 & Play Billing)
- Full setup of App Store Connect & Google Play Console subscription products
- RevenueCat integration, transaction sandboxing, and receipt verification
- Restore Purchases workflow required by Apple Guideline 3.1.1
- Real-time server webhooks sync with your backend user database
Push Notifications & Deep Linking Architecture
