Appstle℠ Subscriptions App

Great support, great product, great options. You can essentially configure any type of payment option you want, and customize the widget to suit your needs. There are a lot of options, which is why it costs more than free, but it's worth it when you don't have to struggle trying to figure out other apps. I also used Shopify subscriptions and it's great, but it doesn't allow you to do options like trials, down payments, and different options that allow you to figure out one-time fees and then subscriptions after, and setup fees and then options. If you have any questions, you always get a reply from their support team quickly. Highly recommended.
