This is seriously impressive. It’s rare to find such a well-done new take on an established category like calendar apps.

A closer look

  1. Create an event by holding its time

    Hold an empty slot and a new event appears there. Slide to adjust the start, and drag the bar at its foot to set the duration. For an all-day event, hold under the date.

  2. Round times by default, exact when needed

    Drags snap to round times. For an exact time, pause before you drag on, or drag the time tag at the left edge.

  3. Riff remembers your regular events

    Type the start of a title you have used before, and Riff suggests the event with its length, place and alert from last time. There is nothing to set up. The suggestions come from your own calendar.

  4. Reschedule with your calendar in view

    Tap the arrows beside an event’s time and it lifts off. Scroll to another week or day, then place it among what is already there.

  5. Three days, each with a weather symbol and its high and low temperatures beside the date.

    The weather where you plan

    Each day’s forecast stands beside its date, and a single day shows it hour by hour. An event pinned to a place shows the forecast there. Weather is a switch in Riff’s settings.

  6. Three days from nine in the morning to eleven at night. The hours after sunset, from about seven on, are shaded slightly darker.

    See when it gets dark

    A faint shade covers the hours between sunset and sunrise where you are, so an evening run before dark is easy to plan. Daylight is a switch in Riff’s settings.

And there is more: reminders beside your events, search by title or place, alerts in a tap, time zones when you travel, a one-thumb zoom…

The calendar itself, as a widget

The Schedule widget is the calendar itself: every event drawn at its hour, with its length and its name. Each size shows as many days as you choose, up to three on the small, a week on the medium and two whole weeks on the large. Month draws this month, or this month and the next, and Up next lists what is coming, on the Home Screen or the Lock Screen.

The large Riff widget: Tuesday 15, Wednesday 16 and Thursday 17 as three columns of hours from 8 in the morning to 8 at night, each event a named block at its time and length. A visit from Grandma and Grandpa spans the top, a morning check-in repeats on each day, and Tuesday's late morning holds four meetings side by side. The medium Up next widget under the heading Tuesday 15: the Grandma and Grandpa visit, Project planning from 10:00 to 11:00, a customer call at 10:30, Roadmap sync at 11:15, and a count of four more.
Three days at true scale on the large widget, the day’s list on the medium.

Your calendars, not copies of them

Work Personal Family

Riff works directly on the calendars already on your iPhone: iCloud, Google, Exchange, whatever Apple Calendar sees. There is no Riff account and nothing to import. Events you create or move in Riff show up everywhere else. Delete the app and your data hasn’t gone anywhere.

Data collected: none

Riff has no server, no account and no analytics. Your events pass between Apple’s calendar database and your screen. Riff adds no stop of its own. Not collecting data isn’t a policy. There is nowhere for it to go.

The best interface for a calendar app I have yet found. Zooming in and out is smooth and adding events is a breeze. I actually like to add more events to my calendar now.
