Customer Ratings & Reviews

I’ve been into fitness for a few years now and I am now age 43. It’s time in my life to start thinking about eating healthier and cutting out the bad habits like candy, soda, fatty foods, etc.. Lumen can help me do that. First off, everything was packaged really nicely inside its box. Included in the box is the lumen itself, with its handy magnetic cap to store away when you are not using it. There’s a carrying pouch a USB-C, charging cable instructions and last, but not least it’s charging base. The first thing I did was start charging my lumen right away. It was fully charged from what I could see out of the box, but I still decided to charge it for an hour or so before I started using it just to make sure. The second thing I did was look at the instruction manual, it’s not overly complicated, but it does give you some important information. The next thing I did was download the app. I’m sure this will get corrected, but on the instructions it says to download the Lumen Metabolism Tracker but the app itself is called Lumen Metabolic Coach. No big deal. I just thought I’d mention that in case somebody is reading my review and wondering the same thing. When you buy a lumen, there is a subscription you eventually have to pay for. I believe you get one month free to start off. This is important information that somebody reading my review should know if they don’t already. In the app, there are “tools” these tools help you with such things as ordering food, logging in everything you eat and drink, and the most important tool in my opinion is the “Scan” basically what it is is you take a picture of what you’re about to eat. it then very accurately tells you what it is. What’s on it and how many carbs, protein, and fat it has. I was amazed at how accurate it was, at first I started taking pictures of fruit. It knew exactly what it was, OK not very impressive right? I took a picture of a ham sandwich and it knew it was a ham sandwich. I took a picture of a tostada that I had a fried egg on top with avocado and queso fresco, it identified that as well. I’m sure it won’t be 100% accurate all the time but I was very surprised at how accurate it was for me. So far everything has been great, between the Lumen device itself analyzing my breath and detecting if i’ve should cut back on carbs, and logging my food in lntake each day, I know exactly how many carbs, protein, calories and fat ive had each day. Seeing these results on paper (or in this case through the app) you’ll get a better understanding and be more conscious about what you eat, and make the appropriate changes if necessary. We all know we should eat better but now you can track it and see it and you’ll be using technology to help you meet yours goals.

I’ve been working with a keto diet and intermittent fasting for some time and have always wanted a tool that would give me a view of what it happening while I’m doing that. I have in the past used glucose and ketosis meters, which involve a pin prick on the finger, but when I found out that Lumen provides a breath-based, dynamic experience to determine what my metabolism is doing, I wanted it. Right off the bat, the tracker was easy to set up. You need an app on your phone, and it connects by Bluetooth, but it was a standard pairing experience, just like your earbuds or car. The app detects the tracker immediately, and there are fun graphics that to me speak to it’s being a life device (breathing type animations, smooth transitions) and it guides you through the process of taking a measurement. You inhale through the device when prompted, keep a dot in a circle for a few seconds, and it then tells you to hold for a short time, and then exhale back through it, again keeping the dot in the circle. The readout is a 5-pane meter, that for all intents gives you how much fat versus how much carb burn you are achieving in the moment. This is great for someone who is doing keto because the hope is you are a “1 or 2” and not in the “4 to 5” range. After you begin the reading process, the app then takes you through a coaching experience that is gentle and useful, with diet suggestions, a motivational component to exercise, and then you can put it away if you are content. It’s a really fun device to be honest if you are doing a keto lifestyle. I can see this as being a useful tool for someone dealing with diabetic symptoms or conditions. Of course, it’s not a substitute for medical care, but it is a great way to keep tabs on yourself everyday. I really am having fun with this from a health standpoint. I highly recommend this if you are using glucose or keto meters, or to supplement your doctor’s monitoring.

Even if this works, at this procing and membership point, there is no way it becomes popular. Odds are the company will not last more than a couple years and you will have a $200 paperweight.
