_01. THE PROBLEM
95% of the world’s population experiences health problems and 60% has difficulties with sleep*.

Half Measures
Generic solutions and sleep/health trackers gather information on how you are doing, rather than help you get where you want to be.

Overlooking Fundamentals
Your body’s biological foundation, the circadian rhythm, is overlooked. Yet, it is the key mechanism behind your sleep and health results.

AYO is Different
Your best sleep and health results start with you. AYO helps you use your own biology to achieve your goals.
*According to The Lancet and the National Sleep Foundation.
