About this app

Do you sometimes suffer from social jet lag with the following symptoms?

- Chronic fatigue
- Loss of performance
- Lack of sleep
- Exhaustion
- Increased propensity for overweight, obesity, diabetes, or other metabolic diseases
- Increased likelihood of addiction
- Connection with mental illnesses

Do you regularly experience difficulties related to the official summer time change to daylight saving time?

Do you struggle to get out of bed in complete darkness in the winter mornings to get to work or school on time?

Do you wake up far too early in summer by glaring sunlight or would you like to make better use of the available daylight?

This app is designed to help synchronize the biological (inner) clock with the processes of the surrounding nature. The user of the app is thus given the opportunity to bring his or her daily rhythm back into chronobiological balance by, among other things, taking in as much natural daylight as possible.

For this purpose, the app "Time's Change" displays an (imaginary) time of our ancestors of the pre-industrial age. Based on this time, called "Native(s) Time," alarms can signal wake-up time, bedtime, and main meals as important chronobiological zeitgebers.
