Events Calendar Shopify Apps – Analytics & Insights

K: Event Calendar holds the top spot for events calendar with 36.1% market share, but the gap to challengers is closing, 33.2pp ahead of The Shop Events Calendar (2.8%). Calee: Events Calendar Widget sits at #3 with 4.3% share, rounding out the top tier. The top 3 apps together hold only 43.2% — meaning events calendar is a fragmented market where lower-ranked apps still capture significant share. InlightLabs ‑ Events Calendar is the standout mover this month, climbing 5 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.

K: Event Calendar (36.1%) and The Shop Events Calendar (2.8%) sit close at the top of events calendar apps, and InlightLabs ‑ Events Calendar climbed 5 positions this month. Current rank is a thin signal in this kind of mover-heavy category — recent climbers often have stronger 6-month trajectory than today's leader.

K: Event Calendar climbed from #12 (Mar 2026) to #1 (Sep 2026) — a 11-position gain among events calendar apps over the charted window.

United States dominates demand for events calendar apps with 51.5% of all tracked installs — a single market that effectively defines the category's product priorities. United Kingdom follows at 12.4%, with Netherlands at 5.2%. Together, the top 3 markets account for 69.2% of events calendar app installs worldwide. Canada (5.2%) and Australia (3.9%) round out the top 5. Australia is the fastest-growing market this month (+0.8pp), pointing to accelerating demand outside the established leaders.

With 51.5% of events calendar 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 (12.4%) and other regions sometimes find better fit in apps that over-index outside United States.
