Oblow is a device that helps you reduce the stress of your daily life or relax at specific moments. Specifically, this device dictates to the user the time of inspiration, retention, expiration and measures if the process is being performed correctly. The app not only allows you to use it as a physical device, but also gives the user a series of tips, statistics and activity data that will help you improve and combat stress and improve your wellbeing.
