How this data was measured
Every figure in this report is computed live from the Toolradar directory on September 17, 2026, covering the 89 published tools we categorize under Calendar. Pricing model is read from each vendor's official pricing page. The entry price is the cheapest positive monthly tier a tool publishes. Ratings and review counts are aggregated from third-party platforms (G2, Capterra, Trustpilot and others), not from Toolradar's own reviews. The leaderboard floor is 150 aggregated reviews. This is a directory snapshot, not a survey.
