For a basic todo list, you might like our app, AnyList (available for iOS):
We are primarily focused on grocery shopping lists, but it'll work fine for other simple lists, and makes it really easy to share lists and collaborate with other people.

Also, thanks for including a list of acknowledgements in the app. I track all of the ones I find at https://www.cocoacontrols.com/apps?o=date, but unfortunately a lot of people simply don't include any OSS acknowledgements.
