This application consists of three modules: RECORDER, SMART ALARM, STOP SNORING. RECORDER Records your talk or snoring while you are asleep (automatic or manual sensitivity level, records only snoring using smart snoring detection), creates the graph of noise in room during the night, takes the total time of snoring down. SMART ALARM Helps you wake up easy in your lightest sleep phase and allows you to get up relaxed every morning. Improve your sleep naturally, maximize your sleep efficiency. STOP SNORING Tries to stop your snoring by playing chosen sound or using iPhone vibration when the snoring is detected. By using the tracker data and by defining your own factors (activities/means/drugs/custom notes) it is possible to find out which facts influence your sleep positively and limit your snoring. At your disposal there are beautiful statistic charts for simple and efficient analyzing of your sleeps/nights. Snoring detection is based on artificial intelligence (A.I.) with the support of a new Apple machine learning technology.
