Show HN: Keep your Heroku app alive

Given that the reason people need to keep them alive is to stay in the FREE tier without the downside - it seems that they would not then turn around and PAY for that to happen.

Big bold teaser text: &quot;alive forever for $9.99&quot;<p>vs.<p>Small grey text: &quot;for 365 days at a cost of $9.99&quot;

I use uptimerobot.com for this - 50 monitors for free

I would hope people do status checks more than once per hour on their web apps.

Seems way too expensive.
