Which iOS and Lion third-party apps support "Documents in the Cloud"? Which apps in iOS and Lion support the "Documents in the Cloud" feature from iCloud? I know that Apple's own iWork apps support this. But other than Apple's own apps, which third-party apps implement this?

It would be helpful to know the name of the app as well as how it uses "Documents in the Cloud". For instance: 


Pages, it allows you to save your documents
Instacast, keep last listened to position in podcasts in sync. 


One app per answer, please, to keep the results focused. Please check before you answer, duplicate answers will be deleted.
I use SigleText (website | App Store link | MAS link) to share notes between my iPhone and my Mac; it uses iCloud storage.
As far as I know, iTunes Movie Trailer app and Doodle Jump app use iCloud storage to sync your settings between iOS devices.
Worth to mention: Instacast. The last version sync your podcasts (played status, favorites, resume playing location) thanks to iCloud. The developer said is going to launch an iPad version, so this feature should be very handy in the future.
