Opt-In Shopify Apps — Frequently Asked Questions
1. Which opt-in app has the highest market share on Shopify?
Judge.me Product Reviews App ranks #1 by share among opt-in apps at 86.5%, 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 opt-in Shopify apps?
For opt-in (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 opt-in apps are gaining market share on Shopify?
Kaching Bundles App & Upsells is gaining opt-in app market share fastest this month, up +7.23pp versus 30 days ago. Switch the table sub-tab to "Market Share Changes" to see all gainers ordered by movement.
4. Which opt-in apps are losing market share on Shopify?
SEOLab: All in #1 SEO — AI SEO has lost the most market share this month among opt-in apps (-9.61pp). Sort the table by Change (Low to High) to see the full list of decliners.

United States drives the largest share of opt-in app installs at 33.6%, followed by United Kingdom at 7.7% and Australia at 6.8%. Use the country picker on the third card to compare market leaders by country.
6. How many opt-in apps does ShopDigest track on Shopify?
ShopDigest tracks 96 opt-in 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 opt-in app differ from the #1 ranked app?
Rank reflects an app's current position in the Shopify App Store under opt-in (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 opt-in, Judge.me Product Reviews App leads on share; see the rankings tab for who currently holds #1 position.
