Plans, anniversaries, wishes, photos. Everything the two of you share, gathered into one app. futari is a couples app to use with your boyfriend, girlfriend or partner. A shared calendar, the count to your next anniversary, a daily question, even games to play together — all in one place. "When are we free next?" "Did you end up buying that?" "Where was that photo again?" The things you used to find by scrolling back through your chat are right there when you open futari. ◯ Shared calendar Dates, work, classes, trips home. Both of your plans in one calendar. The next one shows on Home too, so opening the app is enough to check. ◯ Anniversaries How many days you have been together, how many days until the next anniversary. Right at the top of Home, next to a photo of the two of you. ◯ Today's Question One question arrives each day, and you each answer whenever suits you. Things neither of you would think to ask become a way to know each other. On days you feel like talking more, there are question decks by theme. ◯ Wishes Places to go, food to try, things to make happen one day. Save them as they come to mind and tick them off one by one. For your partner's wishes, a line of encouragement is enough. ◯ Todo Packing for a trip, things to buy, favours asked. Share what needs doing and check it off when it is done. ◯ Album Keep the photos from dates, trips and ordinary days in one place. Photos of the wishes you made happen land here too. ◯ Play The Couple Type quiz, Othello, Memory, take-turns drawing, Werewolf Duet. For spare moments, and for the nights you are apart. ◯ Mood, messages and voice calls How you are today, in a word. There is a chat just for the two of you, and voice calls as well. ◯ Widgets Put the anniversary count, your next plan and your partner's mood on your Home Screen or Lock Screen. ◯ Easy to invite Invite your partner with a QR code, a link, or whichever messaging app you already use.
