Section Store: Theme Sections reached 1,000 reviews in 40 months since launch — the fastest ramp among the top 5 custom code apps tracked here. Attrac Popup, Announcement Bar in 84 months, BOGOS: Free Gift Bundle Upsell in 102 months, and Klaviyo: Email Marketing & SMS took 114 months to cross the same milestone, a 74-month spread between the fastest and slowest in the set.

1 app on this chart hasn't yet crossed 1,000 reviews: CodeUp ‑ Add Custom Code at 7 cumulative reviews. CodeUp ‑ Add Custom Code is closest to the milestone — its current count puts it roughly 1% of the way to 1,000.

The 74-month gap between Section Store: Theme Sections's and Klaviyo: Email Marketing & SMS's time-to-1,000 highlights how unevenly product-market fit landed across this custom code set — the leader found its merchant audience early, while late-rampers took multiple years to reach the same review depth. For merchants comparing these apps today, slower-ramping apps may have closed the functionality gap but still operate on smaller review bases.
