Captcha Shopify Apps — Frequently Asked Questions
1. Which captcha app has the highest market share on Shopify?
Powerful Contact Form Builder ranks #1 by share among captcha apps at 61.0%, 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 captcha Shopify apps?
For captcha (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 captcha apps are gaining market share on Shopify?
Powerful Contact Form Builder is gaining captcha app market share fastest this month, up +11.85pp versus 30 days ago. Switch the table sub-tab to "Market Share Changes" to see all gainers ordered by movement.
4. Which captcha apps are losing market share on Shopify?

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