1. Which cart block app has the highest market share on Shopify?
Essent Cart Drawer Cart Upsell ranks #1 by share among cart block apps at 45.0%, 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 cart block Shopify apps?

ShopDigest tracks 96 cart block 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 cart block app differ from the #1 ranked app?
Rank reflects an app's current position in the Shopify App Store under cart block (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.
