Riff is a calendar that you zoom. Pinch your fingers together and half a year fits on screen. Spread them and a single day opens, hour by hour. There are no month, week and day views to switch between. EVERY STEP OF THE ZOOM IS A WORKING CALENDAR Zoom out to find a free weekend, zoom in to pick the hour. The day you were looking at stays on screen the whole way. EDIT ON THE CALENDAR ITSELF Hold a free slot and type a title. Slide an event to a new hour, or carry it to another week. The days around it stay in view while you edit. WEATHER AND DAYLIGHT Each day shows its forecast, and a faint shade covers the hours between sunset and sunrise where you are. Turn them on in Riff’s settings. YOUR CALENDARS, NO ACCOUNT Riff works on the calendars already on your iPhone: iCloud, Google, Exchange and the rest. There is nothing to import and no account, and no data is collected. Reminders stand beside your events. ALSO Home Screen and Lock Screen widgets, alerts, repeats, search, time zones, Siri and Shortcuts, 30 languages. GOOD TO KNOW Riff is for iPhone and needs iOS 26 or later. You can answer invitations but not send them. PRICE Free for three weeks with everything included. Then choose a monthly or yearly subscription, or a one-time purchase.
