Tankevirus is a video app designed to help you strengthen your psychological immune system. The app starts with a short and entertaining program series about "The Psychological Immune System," "Thought Viruses," and "Psychological Vitamins."

Afterwards, the app presents a new tip video every morning. Each video is brief, lasting only a minute or two, and contains a task or reflection for you to carry with you throughout the day. This helps you uncover thought viruses in your everyday life and practice using psychological vitamins to combat infected thoughts.

In addition, the app also tests your psychological immune system before and after the program. This allows you to see firsthand whether the psychological vitamins have made a difference in strengthening your immunity.
