LetterMe is a non-instant communication app that brings the experience of letter-sending to modern times. Delivery time depends on the physical distance between sender and receiver, making each interaction special. The goal is to provide a slower communication channel where people can have more meaningful conversations without the need to reply instantly. Key features: • You'll get a notification when someone sends you a letter, but you won't know their identity until it arrives. • Customize Your Letters: Say goodbye to plain text – choose your preferred font and paper color to make your letters feel more special. • Track your letters and watch them travel across the world until they reach their destination.

About

passNote

Features
Read full description

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?
