WeTandem is a shared space built for two. Tasks, notes, expenses, calendar, wish list, and the small rituals of life together — synced between you and your partner through iCloud, so you're always on the same page. Tasks, together Create shared to-dos or assign them to each other. See what needs doing today, what's coming up, and what your partner is working on. When a task is finished, say "thank you" with a swipe — small gestures matter. Filter by All, Mine, Today, Errands, or Archive. Set priorities, due dates and times, repeat schedules, and location reminders that fire when you arrive. Streak tasks that slip past their time show up on the Lock Screen with a gentle nudge and a one-tap Done. Whose turn, and little promises Keep "whose turn" cards for the dishes, the walk, the morning coffee — pass the turn with a tap and the other person gets a heads-up. Set up challenges with a stake ("gym twice a week, loser cooks") and mark each round; a forgotten round shows a reminder on the Lock Screen before the day ends. Notes for two Capture ideas, lists, grocery runs, or anything worth remembering. Pin the important ones, color-code by mood, attach a photo, and search everything instantly. Notes sync in real time. Shopping list that's always with you A shared grocery list on the Home screen: either of you adds, either of you checks off. Bought items stay at the bottom until you clear them. Expenses, fairly Log what each of you paid, in any currency, and see this month's total with a fairness line: who's ahead, who's behind, or split evenly. Set recurring bills once and add them to the month in a tap. Wish list Save things you'd love, with a photo and a link. Your partner sees them and can quietly mark one as bought — you'll find a "For you" stamp when the moment comes. A calendar you actually share See your month at a glance: events, task deadlines, and your couple's anniversary in one view. Birthdays and anniversaries repeat every year, meetups every week or month. Tap any day to see what's planned. Evening check-in Pick a time, and each evening WeTandem sends a short note: what got done today and what tomorrow holds. A minute to look back, together. Games for two Sea Battle and Tic-tac-toe on one phone, with a pass-the-phone screen that hides your side. Made for queues, trains, and waiting rooms. A little warmth every day Every morning, WeTandem shows a new quote about love, home, and care — the same one for both of you, wherever you are. Add your anniversary to count the days together. Cycle, shared with care Turn on cycle sharing to read period data from the Health app on your phone and show your partner today's note — a typical pattern for the day, so they know how to be there. Off by default, and only ever read. Widgets, Lock Screen, Shortcuts A Home Screen widget with today's tasks and the next event. Live Activities for missed streaks and challenges. Add a task from Shortcuts or Siri. How it works WeTandem uses your iCloud identity to sync automatically. One person creates a household and invites their partner with a link — that's it. Everything stays private between the two of you. Designed for everyday life Clean, warm design with light and dark themes. Works offline and catches up when you're back online. Adapts to landscape and larger screens. English and Russian. Free, with no subscriptions, ads, or tracking. WeTandem is made for the quiet rhythm of shared life: the grocery list, the shared calendar, the "thanks for cooking tonight." A small app for the things that matter most.
