Kaching Bundles App & Upsells currently holds the highest market share for upselling apps at 32.2%, but the category is competitive — Upsell & Cross Sell — Selleasy is close behind at 31.0%. The right choice depends on your specific store needs.
2. How is market share calculated for upselling Shopify apps?
For upselling (a keyword page), market share is rank-weighted — apps at position #1 carry roughly 40× the weight of apps at position #22, and apps beyond #22 are excluded.

ShopDigest tracks 96 upselling apps on the Shopify App Store. Market share, rankings, and review data refresh weekly so you can track competitive shifts as they happen.
7. Why does the highest-share upselling app differ from the #1 ranked app?
Rank reflects an app's current position in the Shopify App Store under upselling (driven by Shopify's own algorithm), while market share on ShopDigest is estimated from review counts and other factors as a proxy for active installs. The two metrics move on independent dynamics, so the highest-share app and the #1-ranked app are not always the same — and a divergence between them is worth noting rather than assuming one will pull the other along. For upselling, Kaching Bundles App & Upsells leads on share; see the rankings tab for who currently holds #1 position.
