+## Use Pressable Instead of Touchable Components
+
+Never use `TouchableOpacity` or `TouchableHighlight`. Use `Pressable` from
+`react-native` or `react-native-gesture-handler` instead.
+
+**Incorrect (legacy Touchable components):**
+
+```tsx
+import { TouchableOpacity } from 'react-native'
+
+function MyButton({ onPress }: { onPress: () => void }) {
+  return (
+    <TouchableOpacity onPress={onPress} activeOpacity={0.7}>
+      <Text>Press me</Text>
+    </TouchableOpacity>
+  )
+}
+```
+
+**Correct (Pressable):**
+
+```tsx
+import { Pressable } from 'react-native'
+
+function MyButton({ onPress }: { onPress: () => void }) {
+  return (
+    <Pressable onPress={onPress}>
+      <Text>Press me</Text>
+    </Pressable>
+  )
+}
+```
+
+**Correct (Pressable from gesture handler for lists):**
+
+```tsx
+import { Pressable } from 'react-native-gesture-handler'
+
+function ListItem({ onPress }: { onPress: () => void }) {
+  return (
+    <Pressable onPress={onPress}>
+      <Text>Item</Text>
+    </Pressable>
+  )
+}
+```
+
+Use `react-native-gesture-handler` Pressable inside scrollable lists for better
+gesture coordination, as long as you are using the ScrollView from
+`react-native-gesture-handler` as well.
+
+**For animated press states (scale, opacity changes):** Use `GestureDetector`
+with Reanimated shared values instead of Pressable's style callback. See the
+`animation-gesture-detector-press` rule.
