2. How is market share calculated for hydrogen Shopify apps?

6. How many hydrogen apps does ShopDigest track on Shopify?
ShopDigest tracks 47 hydrogen 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 hydrogen app differ from the #1 ranked app?
Rank reflects an app's current position in the Shopify App Store under hydrogen (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 hydrogen, Pandectes GDPR Compliance leads on share; see the rankings tab for who currently holds #1 position.
