 ## Overview
 
-Starting with iOS 18, Apple introduced new system blur materials that create a "liquid glass" effect. These materials provide a modern, translucent appearance that adapts to the content behind them, creating depth and visual hierarchy in the UI.
+Starting with iOS 26, Apple introduced new system blur materials that create a "liquid glass" effect. These materials provide a modern, translucent appearance that adapts to the content behind them, creating depth and visual hierarchy in the UI.
 
 ## Implementation
 
 ### Platform Detection
 
 The app detects iOS version using the `Platform` API from React Native. A utility module (`utils/platform.ts`) provides helper functions:
 
-- `isIOS18OrHigher()`: Returns true if the device is running iOS 18 or later
+- `isIOS26OrHigher()`: Returns true if the device is running iOS 26 or later
 - `getLiquidGlassTint(isDark)`: Returns the appropriate blur tint for chrome materials
 - `getThinMaterialTint(isDark)`: Returns the appropriate blur tint for thin materials
 - `getUltraThinMaterialTint(isDark)`: Returns the appropriate blur tint for ultra-thin materials
 
 ### LiquidGlassView Component
 
-A reusable component (`components/LiquidGlassView.tsx`) wraps the `expo-blur` BlurView with iOS 18-aware logic:
