Add-ons extend the functionality of Slimstat in many interesting ways. We offer both free and premium (paid) extensions. Each add-on can be installed as a separate plugin, which will receive regular updates via the WordPress Plugins admin screen. In order to be notified when a new version of a premium add-on is available, enter the license key in the corresponding field under Slimstat > Add-Ons. Feel free to contact us if you would like to suggest a new feature.
