1. Which back orders app has the highest market share on Shopify?
Preorder, Back In Stock REZ ranks #1 by share among back orders apps at 61.5%, 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 back orders Shopify apps?

ShopDigest tracks 95 back orders 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 back orders app differ from the #1 ranked app?
Rank reflects an app's current position in the Shopify App Store under back orders (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 back orders, Preorder, Back In Stock REZ leads on share; see the rankings tab for who currently holds #1 position.
