Which upselling & cross-selling app is most used by Shopify stores?
Candy Rack is the most widely used upselling & cross-selling app based on StackDex real store detection data. It's installed on 84.0% of stores in our dataset.
How is "trending" different from highest rated?
Trending apps are ranked by actual usage — how many Shopify stores have the app actively installed. Rating is self-reported by merchants, while adoption data shows real market preference. A 4.5-star app used by 15% of stores is more popular than a 5-star app with 0.5% adoption.
How often is this data updated?
Our store adoption data is refreshed regularly through ongoing detection across Shopify stores. The trending rankings reflect what stores are using right now, not historical install counts.
Why do some apps have much higher adoption than others?
Several factors drive high adoption: being available for free, strong word-of-mouth in Shopify communities, featured placement in the App Store, and solving a near-universal need (like reviews or email). The top upselling & cross-selling apps typically address core business requirements that almost every store shares.
