Duet is a shared calendar for couples. Your anniversaries come with reminders, and the things you want to do together can go on the calendar and into to-do lists you can both see. See when your partner is free, never forget your relationship anniversary again, and actually take the trip you keep talking about. Keep everything the two of you share in Duet. SHARED CALENDAR You both see each other's plans, even when you're long-distance. Who's busy this weekend? When do you see each other next? Open the app and you'll know, no more asking "wait, what time was that?" Set weekly or monthly events to repeat, and add a reminder before they start. CALENDAR IMPORT Connect Apple Calendar or Google Calendar, pick one of your calendars, and its events show up next to your shared plans. You decide whether your partner sees them. ANNIVERSARY REMINDERS Birthdays, the day you met, the day you got together. Duet counts the days for you. Set a reminder and you'll hear about each birthday and anniversary ahead of time, plus milestones like 100 days, 200 days, and every year together. HOME SCREEN WIDGET Put the anniversary that matters most on your home screen and see how many days you've been together without opening the app. SHARED WISH LIST The cities you want to visit, the exhibitions you want to see together, the things you'd like for your birthday. Either of you can add to the list anytime. FROM WISH TO PLAN Write notes on a wish. That trip you want to take together? When you're ready, put it straight on the calendar and add to-do lists for it too. SHARED TO-DO LISTS Give each to-do an owner and a due date. To-do lists you add from a wish stay linked to it, so you both know what they're for. Download Duet and keep your plans, your important dates, and what you're getting ready for next in one place.
