What is the technical reason it does not work with an iPad?
I am speculating, but I think it's because they already had separate versions of the Tasty app for iPhone and iPad, and didn't add the feature to the iPad version.
They added the One Top as a new feature to an existing app, rather than releasing a new app.
There is no technical reason the iPad couldn't control it.
