Scrumdo does what it does simply and easily without fuss. It is the ideal tool for those using Scrum and finding that all the tools they look at are overcomplicated, cumbersome and expensive. While it does not have all the bells & whistles, it enables you to easily manage those scrum artefacts essential to the correct implementation and use of Scrum.
It is under active development that looks to be based on feedback and has a responsive and active forum.
If you are looking for a tool without a huge learning curve, to help you manage your scrum process, this is definitely worth a look.
I've been using ScrumDO for months now and it organized my activities in a great way.
Now I'm able to respond to the "When can I have this done?" question.
ScrumDo is as agile and as user-friendly as Scrum!
I manage 10 or so projects at a time. Scrumdo is attractive because of it's integration with Harvest, Basecamp, and GitHub. Each of those tools are good at what they do but they don't support a planning process.

I have played with Pivotal Tracker, Rally and AgileZen and so far I am loving ScrumDo. The prediction feature looks very interesting especially if you guys improve it so you can model potential outcomes when first setting up a backlog. Keep it up.
