Free online application for doing scrum on rails

Question

What is the best free online software to help do agile development and management on my ruby on rails application?

What I am looking for is an online form that multiple people can interact with with the ability to do:

• Planning poker
• Iterations/sprints
• Velocity calculations/predictions
• Backlog prioritization
• Stories with point values

Bonus: And maybe a way to integrate with github

I have tried scrumdo but just wondered if there is a better free application.

Answer 2

All this time (14 years) of professional activity, I've been searching for the best tools. Since Agile Hyping the research continue and I want to give you my piece of contribution.:

I've never seen a tool like Target Process for managment of SCRUM and Kanban.

The tool is AWESOME!

Cons.: Doesn't have Planning Poker. Doesn't have timer to tasks. You have to input.

Pro.: Bugtracking integrated. Constantly updates. Free to 5 people team.

If you want I can share my review of some tested tools.
