UMindMirror is your personal sleep steward, and we aspire to accompany and assist you in having a wonderful night's sleep.If you are experiencing sleep troubles or hoping to improve your sleep quality and develop healthy sleep habits, consider trying UMindMirror. The application, in combination with our developed adhesive-type brainwave sleep device, can easily present multidimensional comprehensive sleep reports, including sleep stages, snoring, body position, and body temperature. This allows you to have a more comprehensive understanding of your health. UMindMirror not only provides scientific sleep monitoring but also carefully selects a diverse range of high-quality sleep music to help your brain achieve a comfortable and relaxed state with beautiful music frequencies at night, resulting in a better sleep experience. The difference between EEG sleep monitoring and other sleep monitoring methods: Human sleep activity is essentially a special stage of brain activity. The human brain state during sleep can be divided into stages such as light sleep, deep sleep, and rapid eye movement (REM) sleep, collectively referred to as sleep stages. Internationally, these stages are defined based on the characteristics of brainwaves, making EEG the gold standard for evaluating a person's sleep process. The UMindMirror system consists of the UMindMirror APP software and the UMindMirror EEG sleep device, which has a lightweight and portable industrial design that is comfortable and imperceptible to wear, and reduces the cost of purchasing and using the device. We hope to bring EEG technology into millions of households and ultimately contribute to improving the quality of national sleep. - Sleep stage: Want to know your real sleep quality? Sleep scoring can provide a comprehensive analysis of multiple dimensions such as duration of light sleep, duration of deep sleep, sleep efficiency, and sleep maintenance rate to give you a score. - Body movement and position monitoring: We can help you understand your sleep state from other dimensions besides brainwave analysis. - Snoring monitoring: I didn't realize my snoring was so loud, no wonder my baby cries at night. If you want to know if you snore at night, for how long, and how loudly, snoring monitoring can playback your snoring sound and also give insights into how your bed partner feels. - Daily, weekly, and monthly report analysis: If your sleep score is unsatisfactory for eight days a month, is it due to long hours at work or staying up late on weekends to browse social media? The monthly report tracking can help you understand your long-term sleep patterns more clearly. - Sleep encyclopedia: What causes your sleep problems? Psychological stress? Eating habits? Unfavorable work conditions? How to solve it? The sleep encyclopedia helps you further understand sleep, comprehend its mysteries, and helps you overcome sleep problems. - Sleep music: After a long day at work, it can be difficult to fall asleep at night. We have carefully selected hundreds of professional sleep music tracks to help you relax, eliminate distractions, and fall asleep to the soothing and beautiful sound of music.
