appless
AppLess is an experimental generative‑UI mobile app that creates every screen on the fly via a streaming LLM, rendering native Cupertino or Material design without any pre‑installed apps.
Why it is worth attention
It recreates a unique scroll-minimizing tab bar behavior not available natively, using real iOS 26 UIGlassEffect and UI-thread animations for smooth, native-feeling interactions.
Who it is for
- Expo developers building React Native apps
- Developers wanting a glassmorphic tab bar with scroll behavior
- Designers aiming for Revolut-style UI
- Teams needing performant, gesture-driven navigation
Use cases
- Bottom tab navigation that minimizes on scroll like Revolut
- Top bar with progressive edge blur
- Custom tab bars requiring scrub gestures and haptic feedback
- Apps needing high-performance animations without JS thread blocking
Strengths
- Real liquid glass effect via iOS 26 UIGlassEffect with hardware-accelerated rendering
- All animations run on the UI thread using Reanimated worklets, preventing frame drops
- Native gesture recognizers ensure no flicker even with rubber-band overscroll
- Pure TypeScript implementation works in Expo Go without custom native code
Considerations
- Requires multiple peer dependencies (expo-blur, expo-glass-effect, etc.)
- True glass effect only on iOS 26+; older iOS and Android use a solid fallback
- Tied to Expo Router's headless tabs structure, not a generic tab bar solution
