+### Coordinate Measurement Correction (Android)
+
+If you notice that the highlight position is slightly off on Android devices—often due to varying status-bar or navigation-bar heights—you can supply `androidOffsetY` to nudge the measured Y-coordinate.
+
+```jsx
+<HighlightToolTip
+  targetRef={targetRef}
+  androidOffsetY={-24} // moves the highlight 24px upward on Android
+  tooltipPosition="bottom"
+  onRequestClose={() => setShowTooltip(false)}
+>
+  <View style={{ padding: 16, backgroundColor: 'white', borderRadius: 8 }}>
+    <Text>Perfectly positioned tooltip!</Text>
+  </View>
+</HighlightToolTip>
+```
+
+> **Tip**
+> Use positive values to push the highlight downward and negative values to pull it upward. On iOS this prop is ignored, so you can safely leave the same code across platforms.
