How do I use the service through Clover?

Clover offers the Waitlist Me app in the Clover Marketplace. You can get the app from there, create an account, and use it on your Clover device. Or, simply log in to Waitlist Me on another Apple or Android device, or through the website. There are monthly and annual subscription options. The only way to upgrade or downgrade is the Waitlist Me website, and you can do so on the Account page.
