Asleep Unveils Digital Medical Device 'ChronoTrack' for Recording Sleep Rhythms

Sleep tech company Asleep (CEO Lee Dongheon) will launch its digital medical device for recording sleep rhythms, "ChronoTrack," in April 2026 to address the field of sleep rhythm management.

Asleep analyzed two years' worth of sleep data from approximately 370,000 individuals and found that 56.2% of Korean adults are classified as evening types, who fall asleep late. This is about twice the global average.

The average bedtime for Koreans is 12:51 a.m., which is later than in the United States (12:24 a.m.) and Europe (12:27 a.m.), and the actual average sleep duration is only 5 hours and 25 minutes. The average social jetlag, defined as the difference in the midpoint of sleep between weekdays and weekends, was found to be 33 minutes, indicating the potential for circadian rhythm disruption.

Sleep rhythm disorders are highly associated with conditions such as insomnia, depression, and metabolic diseases, highlighting the need for clinical management. Although sleep rhythm pattern tests conducted in neurology and psychiatry departments are available as non-reimbursable items under current law, actual prescriptions have been rare due to practical limitations, such as reliance on handwritten sleep diaries by patients.

"ChronoTrack" collects sleep data via smartphone. During sleep, the built-in microphone passively gathers audio signals, and an algorithm automatically calculates sleep-wake rhythm information such as total sleep time (TST), sleep efficiency (SE), and sleep onset latency (SoL), which is then transmitted to a medical institution's dedicated dashboard. Reports can be generated without the need for additional wearable devices or contact sensors.

This device can be claimed under existing non-reimbursable codes, allowing it to be introduced into clinical settings without separate fee schedule procedures. Following its digital medical device for sleep apnea, "ApnoTrack," Asleep aims to strengthen its product lineup for sleep disorders with the release of "ChronoTrack."

Lee Dongheon, CEO of Asleep, stated, "Our data analysis confirms that sleep rhythm disorders are a social phenomenon. ChronoTrack will enhance convenience for patients and healthcare providers, thereby increasing the clinical utility of sleep rhythm pattern tests."
