The investment is co-financed by the Republic of Slovenia and the European Union from the European Regional Development Fund. The "inShift" investment involves the development of a digital solution aimed at eliminating jet lag by gradually shifting the user's natural sleepiness to the desired time zone or hour. It will include an algorithm to identify an individual's biological clock based on data from sleep trackers and an algorithm to generate a personalized protocol for adjusting the biological clock, taking into account the user's personal limitations.
