title: Easy way to prevent Heroku idling?
body: <p>In the Heroku free apps the dynos seem to keep idling - my app has very low traffic but it's also not really acceptable in my case that my users have to wait 20+ seconds to spin up a new dyno. </p>
  
  <p>Frankly, with that kind of wait, many will leave before the first page even displays.</p>
  
  <p>So, I have a problem: should I be paying $36 a month to save each user an embarrassingly long 20 seconds when my traffic is in the single-digits per day.</p>
  
  <p>Is there a way around this??</p>
