title: Wake up heroku app
body: <p>So, my heroku NODE.js app has always been functioning and I was trying it out today again via my url but for some reason it gives me an application error message.</p>
  
  <p>I read about and logged in to my dashboard and it says that the app is asleep..
  I have the free tier of heroku and I understand that the app has to sleep 6 hours in a day(correct?)
  Is there a way to wake up my app? (NOT KEEP IT ALIVE As I have read in other posts, JUST wake it up)</p>
  
  <p>Follow up: Is there a way to know how much time I still have left before it wakes up?(Because of the necessary 6 hours of sleep of the free heroic tier)</p>
