Exchange diaries are a traditional form of communication in Japan, where people share their daily experiences and thoughts through a notebook. Even today, they remain popular among young people, offering a slower and more meaningful alternative to social media and instant messaging. With this app, you can easily experience the charm of exchange diaries on your smartphone. Share your daily life, hobbies, and thoughts while getting to know someone little by little. Unlike short messages, exchange diaries help build deeper connections. By taking time to write and respond, you can learn about each other's values and perspectives and develop lasting relationships. You can also connect with people from around the world. Discover real daily life, culture, school, work, and traditions that cannot be fully understood through travel or social media alone. Exchange diaries are also a great way to learn languages. Built-in translation helps you communicate with confidence while naturally learning real expressions used by native speakers. Why not start a special exchange diary with someone, somewhere in the world?

Know when your closest friends are actually free — without sending a single message. HelloMe is a privacy-first presence app for the handful of people who matter most. Instead of "you up?" texts and unanswered calls, everyone just sets a simple color that says how reachable they are right now: GREEN — Free: open for a call, reach out anytime PURPLE — Text me: can't talk, happy to text RED — Busy: heads-down, please hold off One glance tells you who's around. No feeds, no likes, no endless chat threads — just ambient awareness of the people you love. CIRCLES Group your friends into circles — Close Friends, Family, the gym crew — and set a different status for each. You can be "Free" for family and "Busy" for everyone else, all at once. Each circle gets its own look, so you always know which one you're in. HOW IT WORKS • Sign in with your phone number (a quick one-time code — no passwords) • Add friends by number, or optionally find the ones already on HelloMe from your contacts • Set your status per circle; your friends see it update instantly • Get a gentle notification when a friend becomes free — you choose exactly what pings you, with quiet hours • Tap a friend to call or text through your own apps — HelloMe never messages for you BUILT TO RESPECT YOU • No ads. No tracking. No analytics SDKs. Nothing sold. • Finding friends from contacts is optional — phone numbers are matched on our server and immediately discarded, never stored, sold, or shared • Block and report anyone, anytime • Delete your account and all your data from inside the app, instantly HelloMe is for real friendship, not another social network. Set your color. Be reachable to the people who matter — and invisible to everyone else.
