great app!! highly recommend Sweet Tooth!


Sweet Tooth is awesome, we've place all our partners in this



This is a great addition to any online and physical store! Easy to create a loyalty program and to get it up in your Shopify Store. Exactly what we have been looking for! Also provides great integrations to Klaviyo, Recharge and Gorgias, all the tools we need to offer a professional Rewards program. It help us drive more business and gives our customers a smile every time they receive a reward.


I've just installed it, really easily! And it looks great! Thank you!


Amazing App, my new best friend.

The Art Of Fate

Great thanks to Alex, the loyalty marketing specialist at Sweet Tooth for providing the extensive article on how to build successful Customer Loyalty programs. As a solo-founder of a social enterprise in the fashion industry, it can get extremely difficult and overwhelming to build brand loyalty in a market that is highly over-saturated. The information provided was very helpful and easy to follow, and I was able to integrate it into my e-commerce platform on Shopify in less than a few minutes. Definitely worth a try!

Easy set up - app works smoothly with POS system. So far so good!

Great app, easy to set up and very customizable, but the missing possibility of changing the language takes away a star.
