Great question!

Rocket Genius, the developer of Gravity Forms, also develops some add-ons that are available to customers based on license level. These are listed on their website here (http://www.gravityforms.com/add-ons/) and under the Forms > Add-Ons menu in your WordPress admin area.

They do not list 3rd-party add-ons on those pages. However, they do list 3rd-party add-ons, including ours, on this page: https://www.gravityhelp.com/other-resources/.
