2. How is market share calculated for custom formulas Shopify apps?
For custom formulas (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.

6. How many custom formulas apps does ShopDigest track on Shopify?
ShopDigest tracks 95 custom formulas 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 custom formulas app differ from the #1 ranked app?
Rank reflects an app's current position in the Shopify App Store under custom formulas (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 custom formulas, Simprosys Google Shopping Feed leads on share; see the rankings tab for who currently holds #1 position.
