Resole's Sleepysol BioApp Reaches 300K Downloads via Samsung Health Integration

The quality of sleep is directly linked to the quality of life. The 'Sleepisol Bio' app, developed by LEESOL, a healthcare startup that operates an electroceutical platform for diagnosing and treating brain diseases, has recorded 300,000 downloads, establishing itself as a 'personal sleep coach' that helps many people achieve deep sleep. Sleepisol Bio provides precise sleep measurement and management by linking with Galaxy Watch and Galaxy Ring, based on Samsung Health SDK and Artificial Intelligence (AI). In particular, while existing apps merely provided information, Sleepisol Bio distinguishes itself by utilizing 'brainwave entrainment technology' to analyze heart rate information derived from brainwaves and automatically provide personalized sleep solutions. It induces brainwaves of specific frequencies optimized for deep sleep, and meticulously analyzes the user's sleep patterns and heart rate to deliver optimal sound therapy. It provides an experience as if a sleep expert tailored just for you is by your side. Above all, Sleepisol Bio takes into account the user's 24-hour biological rhythm (circadian rhythm) to provide optimized therapy for each time of day, including morning wake-up, evening sleep, and daytime rest. The fact that all features are provided for free has garnered great popularity among users. Lee Seung-woo, co-CEO of LEESOL, stated, "Over 300,000 people have already improved their sleep quality through Sleepisol Bio." Beyond being a simple sleep management app, LEESOL is enhancing user convenience with a user-friendly interface and continuous updates. Recently, the company has achieved remarkable results, including attracting 4 billion KRW in Series A investment, being selected for Deep Tech TIPS, and winning a CES 2025 Innovation Award (for Sleepisol Lite). It is also actively promoting the overseas market entry of its deep sleep induction device, 'Sleepisol'. Sleepisol Bio will continue to help users maintain more natural and healthy sleep patterns.
