I bought the first level version of Headline studio for $99.00. It actually stops me after about five or so versions of the same headline, as I tweak this or that work, and then demands that I upgrade. I already paid, which pisses me off. So apparently, small print somewhere (not my strong suit) sez you only get X number of version for your hundred. I quit using it because of that. Until that happened I was good with it but I don't make enough money on Medium to justify hundreds and hundreds of bucks on headline software.
