spkids: pretty cool. to the point and real easy to use.

Sport Card Breakers

Super easy to use, great program.


I really love their easy and smooth integration with my store and reward programs helped me to grow my sales. Thank you Sweet Tooth.

Adult Colouring

quick and easy to set up, great app!

Diamond Tiara Boutique

Setting up my discounts was very simple! I can not wait to use the app. I'm expecting great results with all the incentives I set up for my online store.


This app lets you create a great rewards program for your loyal customers. My store sends care packages to deployed military and being able to give commands, parents, spouses, children, etc. who want to support their loved one overseas is just an overall great thing. The only thing is that it, and adding other apps, KILLS your site speed. Keep that in mind when adding apps to Shopify.

Rich In Radiance

Very simple and straightforward set up. The only reason I did not give more than 4 stars is that I haven't put the app in live mode.


Extremely easy to use but lacks customization.

Northwest Beard Supply

Sweet Tooth has been a great program for my Northwest Beard Supply customers. 21 people have found it's value, and looks like they're liking what they see. So are we!

Pretty Jelly

So far so good! The instructions were clear, making it easy to set up. Can't wait to see it in action.
