Store Speed Shopify Apps — Frequently Asked Questions
1. Which store speed app has the highest market share on Shopify?
Kaching Subscriptions App ranks #1 by share among store speed apps at 39.6%, 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 store speed Shopify apps?
For store speed (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 store speed apps are gaining market share on Shopify?
Kaching Subscriptions App is gaining store speed app market share fastest this month, up +18.57pp versus 30 days ago. Switch the table sub-tab to "Market Share Changes" to see all gainers ordered by movement.
4. Which store speed apps are losing market share on Shopify?

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