Then when I try to use in standalone mode, it asked me for an activation key, which is nowhere to be found. When I click on support within the app, it wants me to setup a mail account on my phone. All Bluetooth access and tracking turned on as well. Tried to create an account prior to pairing too, but we need to pair first. What am I missing? This should not be this hard! **Developer response:** Hi, thank you for taking the time to share your experience. We're truly sorry for the frustration. This is absolutely not the experience we want for our customers. The pairing issue, activation key prompt, and in-app support redirect are all things our team can help you resolve directly. Please reach out to us at info@goayo.com so we can walk you through the setup step by step. We'd love the chance to make this right and get you up and running. 🙏 We look forward to hearing back from you. Kind regards, AYO Team ### 3/5 — Recommendations make no sense, bugs *2026-05-21* App is somewhat buggy. Constantly asking for your Rhythm inputs, but keeps asking even after you do it. Then says you’re below average without saying why or how to improve it. Overall very unhelpful app. **Developer response:** Thank you for your honest feedback. We truly appreciate it! We're sorry to hear you experienced issues with the Rhythm inputs. This isn't the experience we want for you, and we'd love to help resolve it. Please reach out to us at info@goayo.com and we'll be happy to assist. Regarding your circadian alignment score, we completely understand the confusion. The recommendations you receive in the app around AYO light therapy, meal timing, exercise timing, and more, are all specifically designed to help improve that score over time. We'll take your feedback on board to make this clearer within the app itself. Thank you again for taking the time to share your thoughts. We hope to hear from you at info@goayo.com so we can turn this experience around! Kind regards, AYO team ### 2/5 — Worthless *2026-01-10* AYO glasses have been good so far, but this app is worthless. It may look nice, but it’s providing me no value whatsoever. Even the basic questionnaire is so poor that it doesn’t distinguish between my natural circadian rhythm and the schedule I’m trying to be on. **Developer response:** Hi there, Thank you for sharing your feedback. We're glad to hear you're enjoying the AYO glasses, but we're truly sorry to learn that the app hasn't met your expectations. Your input is incredibly valuable, and we’re continuously working to improve the experience for our customers. We’d love the opportunity to better understand your needs and help you get the most out of both the app and your AYO device. Please don’t hesitate to reach out to us at info@goayo.com. Our team is here and happy to assist you. Warm regards, The AYO Team ### 2/5 — App is Useless for travelling / jet lag *2025-12-24* If you are looking for jet lag use, look elsewhere. There’s “Social Jet lag” marketing. All fluff. Zero utility. Looks good though. **Developer response:** Hello and thank you for your feedback! We’re sorry to hear the app didn’t meet your expectations for jet lag support. While the app is currently focused on supporting circadian health and controlling the device so you can customize the intensity, session duration and other parameters, it doesn’t yet include a dedicated feature for traditional jet lag. That said, we do offer personalized guidance for jet lag relief to any customer who reaches out. Just contact us at support@goayo.com and we’ll be happy to assist you. We appreciate your input and hope to better support your needs in the future! ### 5/5 — Great App *2025-12-15* Love the glasses and the app. Just after one day I can feel the difference. I get up at 6am and in the winter the sun doesn’t come up until 830am and it’s too cool to be outside. This is a game changer!!! Can’t wait until they add the functionality for travel. **Developer response:** Thank you so much for your feedback! We’re thrilled to hear you’re already feeling a difference after just one day. That’s exactly the kind of impact we hope for! Winter mornings can definitely be tough, and we’re glad AYO is helping you start your day feeling more energized. Thank you for being part of the AYO community! ### 1/5 — Where are the improvements *2025-06-08* This app was always sold on its potential, that they were going to make it great and those of us who bought in were led to believe there were significant improvements that would enhance the functionality of the AYO glasses and enable dialing in personal chronobiology. The reality is entirely different. This app goes nowhere. Either the company is about to collapse and they don’t have money to build what they promised or they’re the most dysfunctional app developers in existence. Either way, there is real dysfunction going on here that should give prospective customers pause about buying in. UPDATE 06/2025: they announced a major update with a lot of fanfare only to bury in the fine print that the useful stuff wasn’t there and is coming later. This company and their app dev effort is a train wreck. Where’s the independent red light sessions or the Apple health integration? Kind of basics. Just not there. If you buy in to this mess, just expect a frustrating experience. **Developer response:** Thank you for taking the time to share your feedback. We're truly sorry to hear about your disappointment and understand your concerns — your experience matters deeply to us. We want to assure you that AYO as a product and company is very much active and growing, and we’ve been making steady progress on both the app and the overall experience. In recent months, we've released a few important new functionalities, and we’re excited to roll out more significant updates in the coming months. Our team is committed to delivering the functionality and value that our users expect and deserve. If you’d like a more concrete update on the upcoming features or timelines, please don’t hesitate to reach out to us directly at support@goayo.com — we’d be happy to provide more details and personally address any questions you may have. Thank you again for your feedback and for being part of the AYO community.

Completely not worth the exorbitant fee that the app costs. Seems like a complete money grab. The glasses work well, but they could have implemented the app functionality into the glasses themselves. They just wanted to charge you extra for a useless app. It’s genuinely embarrassing for the company. **Developer response:** Thank you very much for taking the time to share your feedback. We’ are truly sorry to hear that your experience with the AYO Circadian Health app hasn’t met your expectations. Your input is incredibly valuable, and we take it seriously as we continuously strive to improve our products and services. The AYO app is designed to complement the glasses by providing a personalized experience, including customizing your AYO wearable, tailored guidance and integration with circadian health routines. We understand your concerns about the app’s value, and we’re actively working on enhancing its functionality and features to provide benefits to our customers.  If you’d like to share more about your specific experience or suggestions, we kindly invite you to contact us directly at support@goayo.com. We are committed to ensuring your satisfaction and hope to address your concerns further. Thank you again for your feedback.  Warm regards, AYO Team ### 1/5 — Waste of Money, subpar app & crazy expensive *2024-11-15* I’ve been using the AYO glasses for a week and they have been a game changer. My morning routine has been so much more consistent. I feel like I have so much more energy and find it’s easier to get going in the morning. The app on the other hand doesn’t really have any purpose. I find tracking my circadian rhythm to be much easier on many different apps that cost less and or free. I’m hoping that in the future they do something that adds value since I spent an extra $100 for the lifetime membership. Anyone looking into if the app is worth the extra money my answer would be a clear no. AYO has a lot of work to do and needs to do a much better job at clearly explained what functionality people are getting by purchasing a membership. For my I will continue to use AUTOSLEEP tracker which cost a few dollars for a lifetime. **Developer response:** Thank you very much for taking the time to share your experience with the wearable and app so far. We are very happy that you have been enjoying the wearable and that it has provided a positive impact to your morning routines. On the other hand, we are truly sorry to hear that you have not found the app helpful. If you would be willing to contact us at support@goayo.com to share with us more about your experience with the app so we can improve it, we would certainly appreciate that and would be delighted to assist you. We take each and every customer feedback very seriously and have already shared yours with our technical team for improvement. Please expect a lot of changes to the app and improvements in 2025 that will make it much more useful and insightful. Please also note that if you would like to receive a full refund on your app within the return period, that is certainly possible. Feel free to get in touch with us for assistance in that regard. Thank you and we look forward to hearing back from you.  Kind regards, AYO team ## Frequently asked questions about AYO Circadian Health ### What is AYO Circadian Health?
