What are some good cross-platform to-do applications?

I already know about all the popular ones like wunderlist and any.do etc. I like the look and feel of any.do, so anything like that. Free would be preferred, looking for an app that I can also use in Windows or through the browser.

I would suggest you check out BoostHQ. You can create checklists and polls that are attached to content pieces and share it in topic specific channels that your team members are invited to. You can like, bookmark and discuss.
