ねむり時間計アプリ, also known as the "Sleep Time Meter App," is a lifestyle application developed by OMRON HEALTHCARE Co.Ltd. It aims to help users improve their sleep quality by providing various features and functionalities.

One of the key features of the app is the "Breathing Training" menu, which offers three different breathing exercises to help users fall asleep more smoothly. These exercises, developed under the guidance of an experienced instructor, include the complete breathing method, the Soham breathing method for relaxing the brain, and the count breathing method to calm thoughts and promote relaxation.

The app also supports "refreshing awakening" by allowing users to set their favorite sounds or music as alarms. Additionally, it provides insights into the comfort level of the bedroom environment by monitoring temperature and humidity during sleep.

Users can track their sleep patterns and rhythms, as well as understand their sleeping "type" based on data such as falling asleep, waking up, and sleep duration. The app also offers advice tailored to each sleeping type.

ねむり時間計アプリ is compatible with Omron sleeping time meters HSL-003T and HSL-004T, which can be used to easily measure sleep states and transfer data to the app for analysis.

Please note that the "Sleep Time Meter App" and the associated information site "Sleep Lab" will be terminated on March 29, 2024. For more details, please refer to the notice on the developer's website.
