Always together on your Home Screen. Futamochi is a couples app for iPhone that puts your days together, your partner's doodles and today's photos on your Home Screen and Lock Screen. Draw a heart before bed, and it's waiting on their Lock Screen in the morning. • Most features require Futamochi Premium (paid). One purchase covers you both. Your days-together count and its widget work without it. See "About subscriptions" below. • You both need an iPhone (iOS 18 or later) signed in to iCloud. No sign-up: Futamochi uses your iCloud, so your data lives there, not on our servers. No ads. For dating and married couples, near or far. ■ DOODLES ON THEIR LOCK SCREEN • Doodle on a photo, with prompts and stickers • Your doodle shows up in your partner's Home Screen and Lock Screen widgets almost in real time (iOS decides when widgets refresh) • Doodle time together (up to 8 hours): their doodles appear live on your Lock Screen and, on supported models, in the Dynamic Island • Draw together live, or turn a doodle into a wallpaper ■ WIDGETS 8 Home Screen and 6 Lock Screen widgets: days together, countdowns, your partner's mood, latest photos, distance, today's question and the latest doodle. Send "Miss you" from a widget or Control Center. ■ DAILY LOG Share the photos you each take today, side by side with the time. When your partner posts one, your widget updates. ■ QUESTIONS, QUIZZES AND GAMES • 500+ questions, one a day: answer to unlock theirs and keep your streak going • 13 couple quizzes (how you show love, money, dates…) with your match rate • 5 games with 500+ prompts, like Who's More Likely To and Never Have I Ever ■ SPECIAL DAYS AND CARDS • Milestones every 100 days, monthly and yearly anniversaries, fun numbers like Day 777, birthdays and holidays • Write a card that opens on the big day. Until then, your partner sees only the envelope ■ MEMORIES AND BUCKET LIST • Save memories with a photo, date and place, and see them on your memory map • A bucket list with 200+ ideas. Done? Add a photo and it becomes a memory ■ "MISS YOU" IN ONE TAP • Miss you, Love you, Hug, Thinking of you, Good morning, Good night • Share your mood and how far apart you are (sharing is opt-in; your partner sees only the distance, rounded to about 0.6 mi by default) ■ JUST FOR THE TWO OF YOU • Notifications and doodle strokes are encrypted with keys only your two iPhones hold. We can't see your photos or words • New iPhone? Sign in with the same Apple Account and it all comes back, Premium included (with iCloud Keychain on) • No ads, no tracking. Export or delete your data anytime Getting started: install Futamochi on both iPhones, invite your partner with a link or QR code, and add your widgets. ■ FUTAMOCHI PREMIUM When one of you buys Premium, your connected partner gets every feature too. Without Premium, you can still see your days-together count and its widget, view your special days, connect, restore purchases, and export or delete your data. ABOUT SUBSCRIPTIONS • Premium comes as auto-renewing yearly and monthly subscriptions, or a one-time Lifetime purchase (no renewal). Prices vary by country or region and are shown in the app before you buy • Only the standard yearly plan offers a 7-day free trial, for eligible accounts. It converts to a paid yearly subscription unless you cancel at least 24 hours before it ends • Payment is charged to your Apple Account at confirmation of purchase • Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Renewal is charged within 24 hours before the period ends • Manage or cancel in Settings > [your name] > Subscriptions. Deleting the app doesn't cancel your subscription • If you cancel, Premium stays on until the end of the current period. Refunds are handled by Apple Terms of Use (EULA): https://meojpn.github.io/futamochi-legal/en/terms.html Privacy Policy: https://meojpn.github.io/futamochi-legal/en/privacy.html
