What the review platforms say
Across the six platforms we aggregate, ClickUp holds strong ratings from tens of thousands of reviewers: 4.6 on G2 (13,600+ reviews), 4.6 on Capterra (4,600+), 4.7 on the Apple App Store (9,300+ ratings). Its weakest surface is the Android app at 3.9. The praise clusters on consolidation and customization; the criticism clusters on the learning curve and mobile.
Worth knowing
Two practical notes from the complaint side of the ledger. Subscriptions auto-renew and the refund window is a strict 30 days, so calendar your renewal date if you are unsure about staying. And in 2026 ClickUp disclosed an incident that exposed roughly 900 customer email addresses; no passwords, billing data, or workspace content were involved, and the company published a fix and postmortem. Neither changes the legitimacy picture; both are the kind of thing a careful buyer likes to know.
