Apple testing phone features to detect depression and cognitive decline

Technology juggernaut Apple is attempting to develop phone features that can help spot depression and cognitive decline, according to people familiar with the matter.

In recent years, the iPhone has shifted toward features aimed at improving time management and helping users be more aware of their screen time. Now, Apple is apparently working on technology that aims to analyze users’ traits such as their voices and facial expressions to determine whether someone is experiencing mental decline, according to documents seen by the Wall Street Journal.
