"I want to do this together sometime." "There was something I meant to tell you." "That thing from earlier — it's still on my mind." Too small to text. Too soft to forget. Fuwari is a quiet place where the two of you set those thoughts down, side by side. ■ Don't send it. Just set it down. Messaging apps create a reply the second you hit send. To-do apps create an obligation the second you write it down. But most of what drifts through your head needs neither. "It got cold today." "I wonder if that place is still open." "I want a weekend where we do nothing." Fuwari is built for exactly those — the thoughts with nowhere to go. You don't send them. You float them. And little by little, the two of you start sharing one mind. ■ Two minds, one screen Your thoughts rise from the bottom. Your partner's rest at the top. Soft bubbles, drifting gently into place. No read receipts. No "did you see it?" No "I still haven't replied." They're simply there. Open it on the way home and let your eyes wander. That is what sharing a mind looks like. ■ What you can do with Fuwari • Float it in seconds Open the app, type one line, done. No tags, no photos, no due dates. Three seconds from thought to bubble. • It lands on their screen instantly The moment you float a Fuwari, it appears on your partner's screen. • Notifications that whisper When a new Fuwari arrives, you get a quiet nudge — never a demand. Look when you feel like looking. • Home Screen and Lock Screen widgets You don't even have to open the app. Both of your Fuwari sit right there on your Home and Lock Screen. • When it settles, put it away Done with a thought? Mark it Settled and it moves to your archive. Nothing is deleted — you can look back anytime. It becomes a record of what the two of you were quietly carrying. • React without words When a full reply feels like too much, send a sticker instead. Sometimes "I saw it" is the whole message. • A space with exactly two people in it You connect with a single 6-digit invite code. That's the entire setup. No friend requests. No suggested accounts. No strangers. ■ Made for two people like this • Working couples who barely overlap until the evening • Partners who keep asking "wait, did I tell you that?" • Couples who just moved in together and are still syncing up • Anyone whose important one-liners get buried in a chat thread • Anyone who has installed a to-do app five times and quit five times • Long-distance couples who want to share the small stuff, not just the news ■ Three steps to start 1. Open the app — no account, no sign-up 2. Send your partner the 6-digit invite code 3. Once you're connected, float your first Fuwari We never ask for your email address or phone number. Your shared space takes about a minute to set up. ■ Pricing Fuwari is free to start. Free • Create or join a pair • Hold up to 3 of your own Fuwari at a time • See every Fuwari your partner floats • Send reactions Fuwari Pro — $1.99 / month • Float unlimited Fuwari • No ads • Custom stickers made from your own photos • Pick a bubble color for each Fuwari • Choose a theme for the whole app • Every future Pro feature included Pro is not priced per person. When either one of you subscribes, your partner gets unlimited Fuwari too. Split it, and it comes to under a dollar each per month. ■ Privacy • No one outside your pair can ever see your Fuwari • There is no public feed, no discovery, no resharing • We never use what you write for advertising • No real name, no photo, no profile required ■ One last thing At the end of the day, you get to know what was on their mind. That alone quietly closes the distance left by everything neither of you said out loud. Set something down today. --- Privacy Policy https://binbingin.com/apps/fuwari/privacy Terms of Use https://binbingin.com/apps/fuwari/terms Apple Standard End User License Agreementhttps://www.apple.com/legal/internet-services/itunes/dev/stdeula/ ---
