"Reviewers mostly see Cron as a fast, clean calendar that makes everyday scheduling easier, especially for people juggling multiple Google calendars, time zones, and frequent meetings. They repeatedly praise the intuitive UI, keyboard shortcuts, menu bar controls, quick join links, and availability sharing. The main criticism is limited ecosystem support: many want Outlook, O365, iCloud, Android, and stronger mobile or monthly views. A smaller set also mentions slow feature rollout, occasional crashes, sync issues, high CPU use, and uneven support."
