t-online News Mobile App

Contributed to the t-online news mobile app for Ströer Content Group. t-online is one of Germany's largest news portals; the app provides a native experience for articles, live sports, weather and more.

Areas of contribution

• App architecture: React Native / Expo foundation for a content-driven news app with native navigation.
• Customisable navigation: User-personalisable bottom tab bar with drag-and-drop ordering and persistence.
• Search: Real-time suggestions with debouncing, cancellation and high-performance list rendering.
• Content rendering: Multi-WebView navigation with independent histories per tab and synchronised dark mode between native shell and embedded content.
• Push & deep linking: Notification delivery with content channels; Universal Links / App Links handling.
• Ad monetisation: Native ad integrations and in-WebView ad rendering with refresh logic.

Internal implementation details and vendor choices of the client remain confidential. The list below covers general technologies I worked with on this engagement.

Open-source side outputs

Beyond the app itself, the engagement produced reusable building blocks published on npm, including a custom React Native WebView library tailored to the app's content and ad-rendering needs, and a GDPR-compliant wrapper around the INFOnline/IVW media measurement SDK for iOS and Android.
