Fun Record-Gather Knowledge app for iPhone and iPad

Fun Record is an app that specializes in collecting all kinds of unpopular knowledge.
Explanation of cold knowledge: Cold knowledge refers to trivial and complicated things or knowledge. Maybe the fun is endlessly evocative and full of life around us, but few people pay attention to it.
Cold knowledge can increase peoples knowledge, broaden their horizons, and inspire thinking, triggering a strong thirst for knowledge. Like "cold joke", which is a different kind of humor, cold knowledge is less popular but more attractive.
Come and record those unpopular knowledge you know!
