Riff Calendar is an iPhone calendar built around one continuous, zoomable view rather than separate month, week and day screens. Its homepage describes creating an event by holding an empty time slot, adjusting its start and duration with gestures, and moving it while the surrounding calendar remains visible. Repeated event titles can bring back details such as duration, location and alerts from the user's own calendar history.
Riff works with the calendars already visible to Apple Calendar, including iCloud, Google and Exchange accounts configured on the phone. It also describes reminders, search, time-zone support, widgets and optional weather and daylight information. The site states that there is no separate Riff account or event import and that calendar data remains in Apple's calendar database. The current download requires iOS 26 or later. It is aimed at people who want a different way to view and edit existing calendars, not a separate team scheduling service.
