Read full description

Plain is a third-place app where you can jot down your daily thoughts and share about yourself in a relaxed manner. Start your leisure time with Plain.** ■ Features You can post daily events by collaging multiple images and text. These posts are grouped weekly for easy retrospection. Share your posts with everyone to receive likes and comments from other users. Their empathy and support will encourage you. If you want to keep your posts private, you can do that too. Discover posts from others by exploring topics of interest, and follow those with similar interests and sensibilities to share everyday moments together. ■ The Developer Team’s View We increasingly feel that the bar for posting on social media has been raised. It feels like you have to write something interesting. Even if you write a little something, if the response is lukewarm, you might feel guilty and end up deleting it. You also need to avoid criticism. Drafts keep piling up... Maybe there's no place left where you can comfortably post about yourself. With these thoughts, we created Plain as a place to write about yourself, not for others. Reading someone's record is not just consumption; it brings understanding and empathy. We hope you spend peaceful moments through Plain and that it encourages you to write a little bit about your daily life, not just watch it.
