SecondLock (Chrome Extension)

简体中文版简介

---

A brand new time management tool introduced in the video by @老师好我叫何同学. You need to set time limit every time before entering those fancy websites.

With SecondLock, before entering any fancy website, you must set a time limit for browsing that page. That is the last second your are mindful, you should think twice to set a appropriate unlock duration. Then, enjoy your mindless time. SecondLock will block the webpage when time's up and try to remind you.

Ask yourself before opening an app:

• Why do you open it?
• How long will you spend?
• Do you have any alternative to do?
