CORE DEFINITION

Churn rate (also known as attrition rate, customer turnover, or customer defection) is a metric that measures the proportion of individuals (e.g. employees), customers, or items that leave a defined group during a specified period of time. In business and economics, it is commonly used to assess customer retention and the stability of recurring-revenue models, particularly in subscription-based or

The proportion of users, customers, or employees who leave within a given period relative to the base period, measuring retention and system health; a declining churn rate often matters more than new additions for long-term growth.

Sherlocking

Sherlocking refers to the phenomenon where a platform owner copies the features of a third-party developer's app and integrates them into the platform, thereby rendering the third-party app obsolete. The term originates from Apple's Sherlock search tool, which was introduced in Mac OS 8.5 and later incorporated features similar to those of third-party search utilities like Watson, leading to the coining of the term.

Beat Frequency

The term "beat note" or "beat frequency" originates from acoustics, referring to the interference of two sound waves with similar but different frequencies. The resulting interference signal has a frequency equal to the absolute difference between the two original frequencies, hence the name. This concept is also applied in optics and electronics, where combining two signals of different frequencies yields a new signal with a frequency equal to their difference. For example, consider two sine waves with equal amplitude, no phase difference, but slightly different frequencies.
