42shops review for Smile: Loyalty Program Rewards

We appreciate the clean and elegant design of smile.io. We have installed smile.io in all of our Shopify stores, which not only helps us maintain better customer relationships but also brings real value to our customers — because through smile.io, we offer more discounts to our customers. We believe that smile.io has reached the highest standard of Shopify apps, and whenever we encounter an ugly or inefficient app, we think about how great it would be if the smile.io team designed this product or feature instead. :)
