Whilst the Simba Sleep Coach allows you to track your sleep easily using the microphone of your phone, it is your personal choice if you decide to track your sleep data. It is a little bit like losing weight. Some people prefer to weigh themselves every day to track their weight loss. Others prefer not to and go with how tight or lose their clothes feel. Simba Sleep Coach aims to help you to feel better and healthier. The number of hours slept each night is an important measurement, but not the only one. You decide what motivates you the most. If you don’t know your preference, why not try it out?!
