7. Why does the highest-share quick buy app differ from the #1 ranked app?
Rank reflects an app's current position in the Shopify App Store under quick buy (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 quick buy, Essent Preorder Back in Stock leads on share; see the rankings tab for who currently holds #1 position.
