3 apps on this chart haven't yet crossed 1,000 reviews: Casa Loyalty Points & Rewards at 485, Blocky Fraud Filter IP Blocker at 359, Gift Card Factory at 65 cumulative reviews. Casa Loyalty Points & Rewards is closest to the milestone — its current count puts it roughly 49% of the way to 1,000.
The 39-month gap between CWILL Popup Email Marketing's and Report Pundit: Custom Reports's time-to-1,000 highlights how unevenly product-market fit landed across this custom email 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.
