title: Push notification to IOs or Android from django webapp
body: <p>I have my Django Web app and I want to make a mobile version but it will take me a while, so, I would like to know if it is possible to send push notifications to the mobile phone (either Android, Apple) from the webapp. </p>
  
  <p>The client will run the website normally from the phone and I would like to send a notification when the process made is finished. How can I achieve that ? Do django signals have the effect of push notification ?</p>
  
  <p>Thanks</p>
