Voice Control Apps

Anyone else find a voice control app they like? I have been using Speaktoit Assistant for a few days now and I really like where it is going. Once installed, just long press the search button and your are off and running. I have told it my home address, work address and other personal info and it saves it. Saying "skills" opens a page describing its abilities and "settings" brings up a few options as well. Me and my brother went toe-to-toe this weekend. He has the iPhone 4s with Siri and my assistant was right there the whole way. Siri could do "complex" math like 4 + 4 * 4 = 64 while mine could only do 4 + 4.
