Custom Development Shopify Apps — Frequently Asked Questions
1. Which custom development app has the highest market share on Shopify?
Revoq ‑ EU Withdrawal Button ranks #1 by share among custom development apps at 95.7%, 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 custom development Shopify apps?
For custom development (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. Each app's weighted score is divided by the total weighted score across the keyword to give the share %. This reflects Shopify search behaviour: most installs come from the top of the results.
3. Which custom development apps are gaining market share on Shopify?
Replo Landing Page Builder is gaining custom development app market share fastest this month, up +0.49pp versus 30 days ago. Switch the table sub-tab to "Market Share Changes" to see all gainers ordered by movement.
4. Which custom development apps are losing market share on Shopify?
Mechanic has lost the most market share this month among custom development apps (-0.29pp). Sort the table by Change (Low to High) to see the full list of decliners.
5. Which countries drive the most custom development Shopify app installs?
Germany drives the largest share of custom development app installs at 23.1%, followed by Italy at 16.2% and France at 7.8%. Use the country picker on the third card to compare market leaders by country.
6. How many custom development apps does ShopDigest track on Shopify?
ShopDigest tracks 96 custom development 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 development app differ from the #1 ranked app?
Rank reflects an app's current position in the Shopify App Store under custom development (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 development, Revoq ‑ EU Withdrawal Button leads on share; see the rankings tab for who currently holds #1 position.
