App Review: Social Rhythms - has the pandemic messed with your circadian rhythm?

Using Fitbit data, this Apple product measures a user's sleep-wake pattern and compares it to pre-pandemic behaviour

Social Rhythms combines the latter two, using data from Fitbits or phone apps that use Apple’s HealthKit framework to create reports on the user’s circadian rhythm.

The suggestion is that many people could have fallen into unhealthy sleep–wake patterns, whether related to anxiety, working from home or socialising via smartphones more frequently at night.
