Description by Kosei Endo(from the App Store)
Futari is the gentle, private diary made for two. Write your day separately, then open each other's pages together, at the very same moment.
A SOFTER WAY TO CHECK IN Every day gets a little prompt to inspire you both — something that made you smile, something on your mind, something to look forward to. No pressure, no streak-shaming, just a small ritual that's yours.
SAY HARD THINGS, GENTLY When something you write sounds like it might sting, Futari quietly offers a softer way to say it — so difficult feelings turn into words you'd actually want to send. Built for the moments that are hard to bring up out loud.
OPEN EACH OTHER'S PAGES, TOGETHER Write on your own time. When you've both finished, reveal each other's entries at the exact same moment — no peeking early, no one left waiting to be seen.
EVERY DAY, A LITTLE CLOSER - Days-together counter, from the day you met - Writing streaks for you and your partner - A daily "how well do you know me" couple quiz - Anniversary and special-day countdowns you'll never miss - A shared goal and your next plans together
WORKS SOLO, TOO No partner paired up yet? Futari still works beautifully as your own private diary — your own prompts, your own goals, your own streak.
YOUR LANGUAGE, YOUR LOVE STORY Futari is fully translated into English, Spanish, French, German, Italian, and Japanese, with more on the way — because the little things you want to say to each other deserve to feel natural.
PRIVATE, ALWAYS No ads. No tracking. No public feed. These pages exist for the two of you and nobody else.
