The app is quite barebones, I'd like to have a history of uses. Also changing the light setup doesn't really work even if I'm on a plus device
Response from AYOMar 31, 2026
Thank you so much for taking the time to share your feedback. We really appreciate it, and it genuinely helps us improve!
We hear you on the usage history feature - it's a great suggestion, and we're happy to let you know it's already on our roadmap. We're working on bringing this functionality to the app soon, so stay tuned!
As for the light setup issue, we're sorry to hear it hasn't been working as expected. This is definitely something that should be functioning properly, and we'd love to get to the bottom of it for you. We'll reach out to you directly so we can walk you through it and make sure everything is set up just right.
Thanks again and we apologize for any inconvenience.
Kind regards,

Lichtintensiteit ayo +
Ik heb een vraag, waar ik in de technische specificaties geen antwoord vind: wat is precies de lichtintensiteit? (De intensiteit van dachtlicht is 10.000 luxe, hoeveel geeft ayo plus?)
Response from AYOJan 15, 2026
Hallo en bedankt voor uw vraag!
AYO is een draagbaar apparaat voor (blauwe) lichttherapie en daarom is het meten van lichteigenschappen in Lux (verlichtingssterkte) niet optimaal.
De reden hiervoor is dat, in tegenstelling tot traditionele lichttherapieboxen, de lichtbron zich zeer dicht bij het oog bevindt (in plaats van op armlengte afstand), waardoor "irradiantie" een betere maatstaf is. Irradiantie is in feite de "sterkte" van het licht dat uw ogen bereikt. De irradiantie van het AYO-licht is maximaal 250 µW/cm², vergelijkbaar (d.w.z. binnen de referentiewaarden) met de meest onderzochte en succesvolle blauwlichttherapieboxen.
Met andere woorden, het circadiane effect van het AYO-licht kan worden beschouwd als equivalent aan het circadiane effect van 10.000 lux fel licht, zoals dat wordt uitgestraald door een lichttherapielamp.
Mocht u nog vragen hebben, neem dan gerust contact met ons op. We willen u vriendelijk verzoeken contact met ons op te nemen via [email protected] in plaats van hier een recensie achter te laten, aangezien recensies gaan over ervaringen met het product en niet over het stellen van vragen.
Met vriendelijke groeten,

Helpful App, Glasses Could Be Stronger
The glasses are comfortable to wear, though I do feel the light could be brighter. What really stands out for me is the companion app. It encourages healthier habits by sending notifications and suggesting the best times to sleep, eat, drink coffee, and exercise based on circadian rhythm. It also includes helpful articles and tips, which I’ve found practical and motivating.
So far, I haven’t noticed any major changes from the glasses themselves, but the app definitely adds value to the experience.

Hi there, and thank you for sharing your experience with the AYO wearable and app. We’re glad to hear that you find the app valuable.
We’re sorry to learn that you are not yet experiencing the desired effect. Depending on the intended outcome, light therapy can take anywhere from a few days to several weeks before noticeable results appear. We are here to support you, and a member of our team will be in touch shortly to better understand your experience and see if and how your use of AYO can be optimized.
Regarding the strength of the light, we understand your point, especially when comparing AYO to traditional bright light therapy lamps. AYO uses a very specific narrow-band blue light that is uniquely effective for circadian rhythm adjustment. This is important because of the following reasons:
• Perceived Brightness vs. Biological Effect: The human eye perceives blue light as much less bright than white light. However, for circadian adjustment, this wavelength is up to 3–5 times more effective than broader-spectrum light. This means you get strong biological effects without the discomfort of blinding brightness.
• Gentle on the Eyes: Because of the lack of glare, the light feels soft and comfortable, even at high settings. Yet biologically, it delivers a very potent circadian signal.
• Adjustable Intensity: If you haven’t tried already, you can increase the light intensity in the app up to 100%, which some users find enhances their results.
Thank you again for your feedback. We truly value it and will reach out soon to ensure you get the best possible outcome from your AYO experience.
Kind regards,
The AYO Team

Thank you for your feedback. We’re sorry to hear that you haven’t found the app useful so far. Our goal is to provide a valuable experience, and we’d love the opportunity to guide you through its features so you can get the most out of it. Please feel free to reach out to us at [email protected]—we’d be happy to assist!
In short, the AYO app enhances your experience by allowing you to customize session intensity and duration, activate red light mode, and track your circadian rhythm alignment. It also offers personalized programs (Winter Blues, Energy, Sleep, Metabolism) and provides recommendations on light exposure, meal timing, exercise, and sleep to help optimize your well-being.
We’d love to help you explore these features and ensure you get the best experience with AYO. Looking forward to hearing from you!
Best regards,

Trading data for S.
Improved sleep, but some issues/concerns.
These glasses have vastly improved my sleep and energy. I use them more than the recommended time during the day as I work in a dark room with a computer all day long (usually between 1-3 hours daily). My biggest complaints are 1. The need for an app that is questionable in its privacy policy and 2. A lackluster battery.
The app is nearly useless, and for the developers to have the audacity to charge $100 for a lifetime or $60/mo is absolutely ridiculous. It’s there to steal your data and create a profile by which to make money off of you, obviously.
The battery life is only around 2-3 hours on high usage, which means I have to charge the glasses daily. I was sunder the impression that the case had a wireless charging unit inside - it does not. I have to plug the glasses into the wall daily, and they take about 3 hours to charge.
Overall, I love the glasses and how they have improved my sleep. But, they’re wildly overpriced and there are privacy concerns with the mandatory app.

Hello and thank you for sharing your detailed feedback. We’re thrilled to hear that AYO has significantly improved your sleep and energy levels—helping our customers achieve better sleep and well-being is at the heart of everything we do.
We also appreciate your candid comments, and we’d like to address the points you raised:
App Use and Privacy
We’d like to clarify that the AYO app is not mandatory for using the wearable. You can enjoy the benefits of the product without the app by following the included usage guidelines.
If you do choose to use the app, its purpose is to enhance your experience and provide personalized recommendations based on your preferences and sleep patterns. Regarding your privacy concerns, we want to assure you that we handle your data with the utmost care. Per our Privacy Policy (https://goayo.com/ToU/):
"Such information will not be sold, licensed, distributed, or otherwise provided to third parties without your express written consent, except to process payment information."
Your sleep and health data is used solely to improve your experience and provide better recommendations, and we’re always happy to discuss our practices further if you have any concerns.
App Pricing
We’d also like to kindly clarify a misunderstanding about the app’s pricing. The Lifetime membership is currently discounted to $70 (regular price $299) as we continue to build exciting functionalities that will be launched in 2025. The Annual membership is priced at $59 per year, not per month. We hope this clears up any confusion! Lastly, please note that within the 60-day return period, you can request a full refund of your AYO + app or only of the app and keep the wearable if you prefer this way.
Battery and Charging
The AYO wearable is designed for typical use of 20–30 minutes daily, allowing the battery to last up to a week on a single charge. We’re sorry to hear about your charging frustrations. Regarding the wireless charging case, you may have seen information about our original AYO model (2017-2019 edition), which included this feature. However, due to customer feedback about convenience, charging time, etc., we transitioned to direct charging to streamline and improve the process.
If you’re using the device for extended periods beyond the recommended usage (e.g., 1–3 hours daily), the battery life may understandably be impacted. If you have further concerns about this, we’d be happy to explore potential solutions with you.
We value your feedback and your trust in AYO. If you have any further questions or concerns, please don’t hesitate to contact us directly—we’re here to help.
Warm regards,
AYO team

May or may not be effective in the long run. Flimsy unit and app is not good.
Using it daily for a few weeks now. Not sure how effective it will be in the long run to help with my sleep issues so verdict on effectiveness is out and time will tell but so far, no major improvement on my sleep. However for the price, the item feels flimsy and not well made. Concerned about the longevity of the unit and whether I will get my money’s worth with such a steep price tag. The app is not good. So far it’s proven useless to me and the additional cost, which is very high for an app, is a waste of money.

In case you have any further concerns in that regard, feel free to reach out to our support team. We aim to provide exceptional after-sale customer service.
As for the app’s functionalities, we apologize if they haven’t met your expectations.

Twee maanden geprobeerd, dus echt wel de kans gegeven, maar merk nauwelijks effect.
Kon de bril gelukkig nog wel terugsturen.
