Reviewers frequently mention that the app and daily breath measurements provide insightful guidance for improving nutrition and supporting overall health.

I recently started using the Lumen product, and I am genuinely impressed by how much it has helped me understand my own body’s metabolism. It gives me real-time insights into how my body is processing energy and clearly shows how factors like stress and sleep directly affect my metabolic state.
One of the best features of Lumen is its ability to guide me towards making better choices for my lifestyle. I can now see how a night of good sleep improves my metabolism, while periods of stress can slow things down. This has made me more mindful and proactive in adjusting my daily habits to keep my body in optimal balance.
Overall, Lumen has been a game-changer for me. It’s empowering to have such clear, personalised information about my health and to finally understand the unique story my metabolism tells every day. I highly recommend Lumen to anyone who wants to take control of their wellness journey and make informed decisions about their lifestyle.

Paid for 3 months of the app. Received the lumen device and started to use it. There is a pop up on the app that requests payment information. I've already paid for 3 months. You CAN'T get rid of the pop up without exiting out of the app and closing it. You do NOT have full access to the app without putting in payment information. This is ridiculous!! I already paid. I should have full access. BUYER PROCEED WITH CAUTION!!!

The inconsistency of my breath results is concerning. I can wake up, sit up, take my wake-up breath, and blow a 3. Then I sit for 3 minutes do a reblow and blow a 1. This is the same for every breath. Before I work out, I can blow a 2, wait 3 minutes, and reblow a 4. I don't get it, but the variance is too big for me to trust this device. I've been using the Lumen for 3 weeks now.

Hi Wesley,
Thanks for the review!
When taking measurements within a short period of time, it may be the case that you will receive varying results in your second measurement and thereafter. A deep breath through your Lumen can impact the CO2 levels in your lungs and heart rate, which may cause your second measurement to be higher or lower than the first.
We recommend waiting at least 20 minutes between measurements to ensure results reflect your current metabolic state and to get the best insights.
Please feel free to reach out to our team directly through the in-app chat or by emailing [email protected] if you have any further questions about your results
All the best,

Really impressed with Lumen so far. The app is intuitive, the insights are easy to follow, and it’s helped me become much more aware of how sleep, exercise, and nutrition affect my metabolism and energy levels. Feels like a practical tool that actually encourages healthier habits day to day.

Complete scam, do not buy.! I purchased a Lumen device and a year subscription. After opening the unit and setting up the app. The app asks for your credit card information to set up auto renewal. I don't want auto renewal, but the app holds you hostage and won't allow you access to your already paid for account unless you enter your credit card info. I trying to cancel and was told since I already opened it i can't get a refund. And since I used my HSA to buy it I can't even get my annual subscription refunded? Complete scam!
