They have a provided a FAQ page about Free Dyno Hour [1]
Previously you get 540 dyno hours (18 hours/day), now it's 550. If you provide a valid credit card, you'll get 1000 dyno hours (you will NOT be charged unless you EXPLICITLY switch to a paid plan)

Seems 550 dyno hours are for ALL, not per app :(
This is one feature of AWS they probably had to keep feature parity with.
