Checkout Form Shopify Apps — Frequently Asked Questions
1. Which checkout form app has the highest market share on Shopify?
Blockify Checkout Customizer ranks #1 by share among checkout form apps at 44.5%, but the market is fragmented — multiple apps capture meaningful share. Compare the top 5 on features and pricing before deciding.
2. How is market share calculated for checkout form Shopify apps?
For checkout form (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. Each app's weighted score is divided by the total weighted score across the keyword to give the share %. This reflects Shopify search behaviour: most installs come from the top of the results.
3. Which checkout form apps are gaining market share on Shopify?
Releasit COD Form & Upsells is gaining checkout form app market share fastest this month, up +22.27pp versus 30 days ago. Switch the table sub-tab to "Market Share Changes" to see all gainers ordered by movement.
4. Which checkout form apps are losing market share on Shopify?

6. How many checkout form apps does ShopDigest track on Shopify?
ShopDigest tracks 96 checkout form 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 checkout form app differ from the #1 ranked app?
Rank reflects an app's current position in the Shopify App Store under checkout form (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 checkout form, Blockify Checkout Customizer leads on share; see the rankings tab for who currently holds #1 position.
