Referral Candy & Affiliate

We downloaded this app to try the refer to a friend option. It does integrate well, there is no need of extra coding unless you want to customise the interfaces a bit more. It does integrate with Mailchimp, but haven't quite understood yet if it syncs the info automatically or you have to push them every time. The support team is quite helpful, I spoke to Dwight to get help with the Mailchimp integration part.
