I can see this going one of two ways: either nobody signs up, they get made fun of a bit, get the message and pivot, or the publicity they're generating gets the app in front of the niche they are targeting, they get users, feedback, and the ear of people who put this kind of value on the productivity boost they get.

Either way, I don't see the harm in putting it in front of people now, and I see a big downside to either polishing it more, or pivoting without having tested it on people.
