For couples who work shifts. Each of you adds your rota once, and you both see in one calendar who's working, who's off and which days you're both off: no more asking, no more photos of the rota. And the household stuff too: shopping, chores, notes and trips, always the same on both phones. WORK SHIFTS Set up your shifts with their colour and their pattern (rotating ones included) and the calendar fills itself in. Changing a single day is one gesture, not a rebuild of the whole pattern. If you both work shifts, each of you has your own and you see them side by side. A GENUINELY SHARED CALENDAR Month, fortnight, week and day views. What one of you creates shows up on the other's phone in seconds, with nothing to refresh. And it keeps working with no signal: it syncs when you are back. YOUR OTHER CALENDARS, INSIDE Bring in the calendars you already have on your iPhone — iCloud, work, or the Google and Outlook ones you have set up in Settings — and see your usual events next to the group's. One for free, up to five with InSync Pro. You decide which ones are shared and which stay yours. LISTS AND ERRANDS A shopping list sorted by supermarket, tasks with someone assigned to them, and notes with checklists. Tick things off from either phone. TRIPS Plan the trip day by day: journeys, accommodation, itinerary and whatever attachments you need, in the same place as the rest of the calendar. WIDGET AND SIRI Home screen widgets: today and this week, free; the month, four weeks and the shopping list, with InSync Pro. And you can ask Siri what you have on today without opening the app. ALERTS Reminders for your events, and a heads-up when the other person adds or changes something. Events you import from other calendars never trigger notifications. PRIVACY Your data belongs to you and to the people you share the calendar with. No ads and no selling your data. We only count, anonymously, which parts of the app get used. You can delete your account from inside the app. INSYNC PRO The essentials are free: the shared calendar, the shifts, the shopping list, the errands, the today and this-week widgets, and one trip, one note and one list. With InSync Pro: up to 6 people in the group (shifts for two of them), 5 external calendars, 100 trips, 500 notes and 500 lists, 500 MB for attachments, 10 shift styles and the month, four-week and shopping list widgets. It is a monthly or yearly subscription; the yearly one starts with a free trial, and you see how long it lasts before you subscribe. The subscription renews itself unless you cancel at least 24 hours before the period ends; you can manage or cancel it in your App Store account settings. No ads and no data selling on either plan.
