## What is Sponge Time?

This app helps you manage your time effectively, optimize time allocation, and truly take control of your time.

【What is the Lyubishchev Statistical Method?】

Alexander Lyubishchev, a Soviet entomologist, philosopher, and mathematician, used his self-created time statistics method to utilize time extremely efficiently. He published over 70 academic works in 56 years, and his personal collection of flea specimens was five times that of professional research institutes.

The statistical method is simple: record time → perform statistics → adjust allocation. The difficulty lies in persistence. Now this app helps you easily maintain this habit.
