I've created an app on Heroku with one web dyno. If no traffic it will idle, thus take about 20 seconds to spin up on first visit.
If I add a Heroku Scheduler add-on to the app to prevent idling, what is the cost if it goes beyond the 750 free dyno hours?
Can I create a separate app (with another 750 free dyno hours), set the web dyno to zero and run the Heroku Scheduler add-on? Does this imply that I can process 750 dyno hours with the heroku scheduler add-on since no web dyno is set?
