About Foster 漫郵
Foster Mail is a slow-paced social letter-writing app that brings communication back to the simple act of "writing, waiting, and receiving."
In the world of Foster Mail, everyone is assigned to a different country based on their personality and traits through a psychological test. Here, you can choose different regions and keywords of interest to match letter recipients, select messengers and stamps, and letters will take different delivery times depending on the distance.

Besides sharing daily life and having heart-to-heart talks, you can also chat with strangers about the past or values through daily questions. If you want a more advanced experience, you can use the physical Foster Mail feature to actually send letters, or participate in blind box giveaways to send your sentiments to like-minded strangers.
