react-native-session-length

#Why If you want to timeout people's sessions or show something when they have opened the app for the first time in a while. This covers the both use-cases of :

• Bringing the app to the foreground.
• Opening the app from force close.

#Usage

import SessionLength from 'react-native-session-length';

SessionLength((milliseconds)=>{
  console.log(`It has been ${milliseconds}ms since you last opened the app.`;
});
