Customer Fields Shopify Apps – Analytics & Insights

Helium Customer Fields holds the top spot for customer fields with 25.0% market share, but the gap to challengers is closing, 20.1pp ahead of Accentuate Custom Fields (ACF) (4.9%). Mini:Custom Fields Personalize sits at #3 with 3.1% share, rounding out the top tier. The top 3 apps together hold only 33.0% — meaning customer fields is a fragmented market where lower-ranked apps still capture significant share. Mini:Custom Fields Personalize is the standout mover this month, climbing 6 positions — a momentum signal worth tracking. Worth noting: the top-ranked app and the highest-share app aren't the same here — App Store rank and our market share metric (computed from review counts and other factors) move on independent dynamics, so cross-checking both views matters in this category.

Helium Customer Fields (25.0%) and Accentuate Custom Fields (ACF) (4.9%) sit close at the top of customer fields apps, and Mini:Custom Fields Personalize climbed 6 positions this month.

United States dominates demand for customer fields apps with 33.9% of all tracked installs — a single market that effectively defines the category's product priorities. United Kingdom follows at 9.3%, with Australia at 6.9%. Together, the top 3 markets account for 50.1% of customer fields app installs worldwide. Japan (5.1%) and Canada (5.0%) round out the top 5. Japan is the fastest-growing market this month (+0.7pp), pointing to accelerating demand outside the established leaders.

With 33.9% of customer fields app installs concentrated in United States, the leading apps in this category typically prioritize United States-based merchants for localization, currency, and support hours — merchants in United Kingdom (9.3%) and other regions sometimes find better fit in apps that over-index outside United States.
