I know. The intent of the post was to ask if there is an app for this purpose. I am sure Apple knows about this. I don't think they consider it a flaw.
You've probably read it elsewhere in the Forum but there is a workaround for the annoying autocorrect. A Member noticed that the iPad never autocorrects names in the Contacts app, so he suggested entering frequently 'autocorrected' words there as a 'spoof' contact. It works wonderfully if the iPad is constantly autocorrecting business or technical or other terms. For sure, it's a work around, but it does work.
