Certification Shopify Apps — Frequently Asked Questions
1. Which certification app has the highest market share on Shopify?
Tevello Courses & Communities currently holds the highest market share for certification apps at 59.7%, but the category is competitive — Courses Plus is close behind at 25.4%. The right choice depends on your specific store needs.
2. How is market share calculated for certification Shopify apps?
For certification (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 certification apps are gaining market share on Shopify?
Courses Plus is gaining certification app market share fastest this month, up +3.72pp versus 30 days ago. Switch the table sub-tab to "Market Share Changes" to see all gainers ordered by movement.
4. Which certification apps are losing market share on Shopify?

5. Which countries drive the most certification Shopify app installs?
United States drives the largest share of certification app installs at 42.0%, followed by United Kingdom at 10.0% and Australia at 7.3%. Use the country picker on the third card to compare market leaders by country.
6. How many certification apps does ShopDigest track on Shopify?
ShopDigest tracks 96 certification 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 certification app differ from the #1 ranked app?
Rank reflects an app's current position in the Shopify App Store under certification (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 certification, Tevello Courses & Communities leads on share; see the rankings tab for who currently holds #1 position.
