+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.

 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

 It is expected to look good on every device you want - iOS or Android, phone or tablet, basically anything (please let me know if not).  
 There are also some attached screenshots in the repo if you don't feel like cloning.
