 When developing with react-native, you need to manually adjust your app to look great on a variety of different screen sizes. That's a tedious job.  
 react-native-size-matters provides some simple tooling to make your scaling a whole lot easier.  
 The idea is to develop once on a standard ~5" screen mobile device and then simply apply the provided utils.

 Sometimes you don't want to scale everything in a linear manner, that's where moderateScale comes in.  
 The cool thing about it is that you can control the resize factor (default is 0.5).  
 If normal scale will increase your size by +2X, moderateScale will only increase it by +X, for example:  
-➡️ scale(10) = 20  
-➡️ moderateScale(10) = 15  
-➡️ moderateScale(10, 0.1) = 11  
+➡️ scale(10) = 20  
+➡️ moderateScale(10) = 15  
+➡️ moderateScale(10, 0.1) = 11  
 * `moderateVerticalScale(size: number, factor?: number)`  
 Same as moderateScale, but using verticalScale instead of scale.
