Tshirt Shopify Apps – Analytics & Insights

SB Custom Product Designer holds the top spot for tshirt with 36.2% market share, but the gap to challengers is closing, 36.2pp ahead of PODbazi: Tshirt Product Design (0). Gelato: Print on Demand sits at #3 with 58.2% share, rounding out the top tier. Together, the top 3 apps absorb 94.4% of all tshirt installs — a highly concentrated landscape with limited room for new entrants. Tshirtgang Print On Demand is the standout mover this month, climbing 3 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.

SB Custom Product Designer leads at 36.2%, only 36.2pp ahead of PODbazi: Tshirt Product Design (0), with rankings stable this month. When the top two tshirt apps demonstrate similar real-world adoption, fit-for-store usually matters more than rank — comparing pricing model, integration depth, and support hours separates them better than the share gap does.

SB Custom Product Designer held #1 steadily from Sep 2025 to Sep 2026 — an entrenched leader in tshirt that challengers haven't displaced. Across the top 5 plotted tshirt apps, 2 improved their ranking while 1 declined — the category is moving upward overall. SB Custom Product Designer's share held near 36.2% from Sep 2025 to Sep 2026 — a stable install base for tshirt apps rather than active gain or loss.

Stable rankings across the top 5 plotted tshirt apps mean merchants have largely settled on their preferences — challengers below the top 5 face an uphill path to break in.

United States dominates demand for tshirt apps with 39.4% of all tracked installs — a single market that effectively defines the category's product priorities. United Kingdom follows at 9.8%, with Germany at 9.7%. Together, the top 3 markets account for 58.9% of tshirt app installs worldwide. Canada (7.1%) and India (4.9%) round out the top 5. Canada is the fastest-growing market this month (+1.8pp), pointing to accelerating demand outside the established leaders.

With 39.4% of tshirt 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 (9.8%) and other regions sometimes find better fit in apps that over-index outside United States.
