[Noloop] App is an application that helps you break free from algorithmic and become the master of your time. It assists you in returning to a slow-paced life and rediscovering inner peace and strength. This is a software full of vitality, with green as its main color tone. It is a composite software integrating simple page design and multiple practical functions: • Application Control:Freely set the usage duration of each app to be the master of your time. • Sleep Mode:After enabling, only specified apps remain available, while others are blocked, allowing you to sleep soundly. • Time Management:Independently control the total daily app usage time, and the system will automatically restrict app usage when the limit is reached. • Parental Control:Restrict app downloads, deletions, and in-app purchases to safeguard children's mobile phone use. • Anti-Gambling Consumption:When enabled, it effectively blocks virtual consumption behaviors such as game recharges and other "氪金" (gambling-like spending) activities. • To-Do List:Plan daily tasks and to-do items independently, keeping life organized. • Focus Mode:Choose focus duration and meditation music to help you quickly enter a state of flow and enhance concentration. • Return to Peace:Press this switch, and the world becomes quiet. This app has no annoying pop-ups or embedded advertisements. We hope to bring real help to users through a pure experience. The slogan of "Noloop" – Return to a slow life and rediscover inner peace and strength – is exactly our original intention and pursuit. Note: "氪金" is translated as "gambling-like spending" to convey the concept of impulsive, addictive consumption similar to gambling, which is a common term in Chinese internet culture.
