Trying to find a Collaborative Task Management App

I'm looking for a good iPad app to assign task to a group of team members, no more than 5. Basically I want to assign a task/job/etc to a list, have the other 4 members see the task, and one mark it done. This all needs to sync with a cloud based server, push notification would be nice.

I've downloaded probably a dozen, all falling short of the simple goal I have in mind.

Asana-completed tasks disappear once completed and can only be viewed by one person

Intellinote-organizations can't seem to remain inline and is very cluttered

Cloudship-can only assign to one person

And theres a slew of others I couldn't even try to make work.

So does anyone have any app recommendations for what I'm trying to do?

Basically all I want is a glorified Notes app synced with iCloud on 5 iPads.

Thanks for the help!

 

Thanks for the links. Igloo looked really good, made an account etc but the app keeps crashing on launch, latest iPad, iOS 7.1.2, ugh so close.

I'll give Wunderlist another shot. I looked at that as my first few and didn't like something, but now my standards are lower. Ha. Thanks!

 

Great, any other recommendations you got would be awesome. I'll keep checking. Thanks

 

Still can't find anything despite getting calls from several developers on why I stopped setting up their applications

So I'm still looking for an app that can list tasks without assigning to ONE person. I need our entire group of five to view and mark completed if necessary. Thanks!
