スマホ依存度診断 is a free Android app developed by Testii. In today's modern world, smartphones have become an essential part of our lives, always being carried with us. This app aims to diagnose the level of smartphone dependency in individuals through a series of 15 random questions and psychological tests. Whether you want to assess your own smartphone dependency or have a friend who seems to be highly dependent, this app provides an opportunity to gain insights. It is recommended for those who are curious about whether they are suffering from "smartphone addiction," as well as for those who enjoy psychological tests, horoscopes, and quizzes. The app is easy to use and provides a simple way to pass the time. It is also linked with Testii's "みんなの診断" (Everyone's Diagnosis) for users to create and share their own diagnoses. Additionally, Testii has recently launched "Chatii＊恋愛トーク" (Chatii＊Love Talk), a conversation service for discussing topics related to love and relationships. This app is free to download and play, with advertisements displayed to support its continued availability.
