Review: Excellent health insights, comfortable to wear and great battery life - I recently started using the Ultrahuman Ring and my experience so far has been very positive. Quick Highlights: Very lightweight and comfortable to wear, especially during sleep. Excellent analytics and health insights in the Ultrahuman app. Automatic nap detection works very well. Battery lasts around 4 days on a full charge. One of the biggest advantages for me is that I no longer need to wear a smartwatch during sleep. The ring is lightweight, comfortable, and hardly noticeable while sleeping. The analytics and insights provided in the Ultrahuman app are top class. The level of detail around sleep quality, recovery, HRV, movement, and overall health metrics is very impressive. It actually takes some time to fully understand all the insights and how to use them to improve different health parameters, and I feel it will take me a couple of weeks to explore everything properly. Another feature I really liked is the automatic nap detection. Even if I sleep for a short time during the day, the ring detects the nap automatically and records it in the app, which contributes to the overall sleep analysis and sleep score. The battery life is also very good. Once fully charged, I do not need to worry about charging it for around four days, which makes it very convenient for daily use. Overall, it is a great product and a very useful addition for anyone who wants to improve their health routine and understand their body better.
Review: You may get a DEAD ring and you cannot do anything about it - The sizing kit for Rs. 150 gives better value than the Rs.30,000 ring which is shipped as dead. At least you dont expect the sizing kit to work. Important realizations : * Ultrahuman DOES NOT HAVE PRODUCT SUPPORT for a Rs.30,000 product (hope you won't have to learn it the hard way). * There is no channel you can raise a ticket which assures any response and reasonable turnaround time Day 1 : * Ring was delivered which I ordered the previous day. Happy with ultra fast delivery * There is a joke called open box inspection which they make you pay separately, where they will open your package take a picture. Don't be fooled - this is only to mark that you have inspected the product and approved it is all good. * Remember, it will take at least 1-2 hours for you to functionally inspect the product first time by charging and connecting to the app, which they don't tell. Day 1 (after 4 hours charging; they say 0-100 will be done in 2 hours) : * Finds out that your ring is not detected in bluetooth, not connecting to the app and it is just a brick. * Tries all troubleshooting steps mentioned in the support section of Ultrahuman app * App gives up and suggests that it is a 'Dead on arrival' situation and need to talk to support through the app * Creates a support request through the app. It gives a message 'We have an unusualy high amount of requests and we will get back soon' * Noted as THERE IS NO HUMAN MONITORING FOR ISSUES LOGGED THROUGH APP Day 2 (24 hours after creating the ticket through app) * The support request is still not picked up. You cannot do anything more because it says I have already created the issue and cannot create again * Raised a ticket to desertcart support (from where I purchased the app) - desertcart support gave an email and phone# to contact Ultrahuman support - Assures that they work 10 AM to 6 PM, 7 days a week * Tried calling support helpline and realizes THERE IS NO HUMAN OPERATOR FOR PHONE SUPPORT. Support phone number only gives a recorded response that we received the request and will get back soon. Day 2 (8 hours after logging support request through phone; 36 hours after logging issue through app) * Sends an email to support@ultrahuman.com explaining the issue * Realizes that there is NO HUMAN MONITORING OF EMAIL SUPPORT. Gets an automated response we will get back. Day 3 : (12 Hours after logging issue through email; 20 hours after logging issue through phone ; 48 hours after logging issue through app) * No response from app, phone, email requests after 48 hours * Created a product return requests with desertcart and explained the situation. Hopefully they will take back this junk and will return the money.

### ⭐⭐⭐⭐⭐ BEST RING EVER
*by A***A on 25 March 2026*

Honestly, the Ultrahuman Ring Air has been such a smooth addition to my daily routine. It’s super lightweight and comfortable - I barely even notice I’m wearing it, which makes it perfect for all-day (and night) use. What I really love is how it tracks sleep and recovery. It’s helped me be a lot more mindful about my sleep and energy levels without putting in too much effort. The app is clean and easy to use, and the battery life is great, so you’re not constantly worrying about charging it. Overall, it just fits into your life without being annoying or distracting. 10/10 would recommend 👍
