Jott is a service that you can call and transcribe notes to yourself. If the computer can't dictate it it is sent to a real person who transcribes it and sends it to your email or on your account. I used this when it was in beta and it works pretty good. I think they have started charging for most of it now. Works really well that you can setup other people to Jott to, when you call in it asks you who you want to jott, so if you wanted to send a message to your wife while driving you would call say Jott to Wife and dictate the message and it would send the message.

But that is a service, not an app, probably not what your looking for.
