What tablet optimised apps are you missing?

The tablet situation in android is rapidly improving. The last few months alone, tons of major apps got updated to support the nexus 10 res. But still there are plenty of apps that look like vomit or not tablet optimised. One of them is twitter. (lol..) Thankfully there are many awesome twitter clients like falcon (which got removed..). SO what are your favorite apps that are not optimised for tablets?
