Store description excerpt

## Existing messengers are distracting your focus. Ever open your smartphone and see a red dot of unread messages and think it's a distraction? That thing is the most evil of the great inventions of this century. Why do Facebook, Instagram, and many other apps like WhatsApp display a red dot on the screen? Humans are designed to pay attention to a red dot when it appears in their field of vision, and the software we use these days, messengers, understand human cognition and display it intentionally to gain attention. For example, if I belong to a school or work community, and I am a member of that community's messenger group, I may have received a lot of notifications of messages that have nothing to do with me, and I may have considered them disturbing. Even if you find it disturbing, you probably cannot leave that messenger group. If you do, others will be suspicious that you left the group and will ask you questions at a later date with worried looks on their faces. I also wondered if I needed to keep a history of my messages. Sometimes leaving a message history can make you overly concerned about that person. This is natural psychology, but it is no small pressure for me to feel that I need to send a message to that person as soon as possible. In the case of important business messages, I have to make sure I don't miss a message from the other person, and it is important that the history is kept, so existing messenger applications such as WhatsApp are very effective for that use case. However, when asked if red dots and message history are necessary for daily conversations with friends, family, lovers, and other private and connected people, I do not think it is necessarily an important factor, and in fact, I think it creates unnecessary pressure that we do not need to feel I have come to think that it is. ## Wissu (Ossu) This is a familiar sound to Japanese speakers. Wissu, or Ossu, or whatever you want to call it, this pronunciation has a lot of context, depending on the case. - Hello. - Excuse. - See you tomorrow. - Sorry. - Thank you for the good food. Communication via software has evolved too much. We should be able to do it rougher and slower. This app allows you to send a message to the other person. You cannot do anything else. All message communication is done via push notifications, there is no history of messages, and no data is stored on the server in the first place. There is no on-screen indication of when a message was sent. It is dedicated to sending text. By doing this, we aim to make it easy for people to send messages to those they want to send them to, for the recipients to feel like they can reply when they want to, and for people to free up their brains by slowing down the amount and speed at which they consume information, which has risen dramatically with the development of technology. There is no need to feel sorry that you haven't replied, or sad that you haven't received a reply from the oth
