Joyio by Avada is a Shopify app designed to boost customer loyalty through rewards, referrals, and gamification. This review covers its features, pricing, and real merchant experiences to help you decide if it’s the right fit for your store.
A little frustrating that the app is still very much in development. I ran into a lot of bugs which took awhile to work around (still working on several, actually...but we've only been setting up the app for a short time now). Kinda half-baked from a coding/development perspective. That being said, the team behind this app are very responsive and helpful. If you have the time and patience to walk through everything, you can get a pretty good thing going.
