Frequently Asked Questions


We want to make sure you’re happy with your purchase. However, in case you are not satisfied with your AYO and would like to return it for a full refund, and you have purchased it on our website, you can do so within 60 days from the day you received your complete order. The product must be returned with its original packaging and in good condition (as good as new). Please note that all purchases made during a sale event (with a discount equal to or above 30%) are not eligible for a refund or 60-day money back guarantee.


Additionally, note that if you have purchased the Annual or Lifetime package, we do not provide refunds for the AYO app (only for the AYO wearable). If you would like to cancel your AYO app annual subscription, you can do so by contacting us at

AYO Wearable

A typical AYO session is 20 minutes. AYO was designed in a way that it seamlessly fits with your lifestyle, allowing you to continue with your daily routine while wearing it (e.g. cooking, working on the laptop, brushing your teeth, etc.)

Science & Results

AYO is based on light therapy and the science of Chronobiology. Light therapy is a widely-used and recognized method for improving mood, energy levels and sleep quality, backed by thousands of peer-reviewed articles and studies.


Additionally, AYO is participating in numerous clinical studies with leading institutions worldwide. Two of them, with the US Department of Defense and the University of Reykjavik, are already published and have shown AYO to be effective in decreasing sleep problems, improving sleep quality and increasing performance. 


You can learn more about the science behind AYO on our Science page.

Some of our customers report experiencing positive effects on their energy levels and mood already after just one session with AYO. Others need several days to a few weeks in order to feel a lasting change in their sleep quality and circadian rhythm. We recommend daily usage for at least 3 weeks in order to start feeling the desired effects.
