What merchants praise

This app blew me away! It is EXACTLY what I was looking for but even better. And the customer service is absolutely incredible and very fast. The ability to customize the product recommendations, design, and placement is amazing. Could not have been easier to set up. Can't wait to check out analytics after a few weeks of setting these funnels up. Highly highly recommend! [update] still using this app and absolutely loving it! I figured out how to customize the design of my offers with different templates and backgrounds - very cool! Customer service is STILL 10/10!

Install footprint is observed via Ongoing.AI’s tech-detection pass against actively-tracked Shopify storefronts. Catalog position is computed at snapshot time against every active app sharing the primary category. Snapshot generated .
