Is there a difference between to be "on" and to be "running" for a dyno?

https://www.heroku.com/pricing says that:

  1. a free dyno "Sleeps after 30 mins of inactivity, otherwise always on depending on your remaining monthly free dyno hours."
  2. a hobby dyno is "Always on"
  3. in case of hobby dynos: price is $7/month, and "You pay for the time your dyno is running as a fraction of the month."

My app will get approximately 5 requests per day which it will serve in 3-4 milliseconds each.

I think about changing from free dynos to hobby dynos to avoid sleeping. How much will I pay?

Am I right that it is only 5x4x30 milliseconds = 600 milliseconds running time in a month which is approximately $0? Or should I pay the whole $7/month?

I'm also wondering this myself. There's no clear answer on Heroku's website. The so called price "calculator" doesn't allow you to customise the number or type of dynos, let alone enter a estimated number of running minutes.

Judging by some of the comments on forms, I'm guessing it's the full $7 per month but it would be great if this could be clarified.

Answer: The price is $7 per month and there is no option for the dyno to sleep. Dynos can be turned off but this potentially disables functionality on the deployed application.

Also Note: You can't alway mix dyno types so you might have to pay for a worker dyno in addition to web dyno. This can be a real sting when you've been testing/developing with free web and worker dynos. So the jump is not necessarily from $0 to $7, but $0 to $14 per month.
