Lumen-interesting insights

I really do love my Lumen; it has provided insights into how my metabolism works. Because of that, I am making better food choices and loosing some weight. Thank you!

Customer Service

Price is way to expensive for what you get and customer service is very hard to get in touch with. No phone number to call and mostly just an Ai chatbot to talk to. If you get “transferred” to a real person via chat (cause that is the only option) the you may as well just send an email because the real person on chat takes just as long to reply. Any reputable company would have a phone number to call and ask for help asap….not make the customers wait for mailing the details of the issue(s)

App used to be good but sucks now

I’ve been using my Lumen for a year and a half. The app used to function seamlessly and I found the bar code scanner and photo feature for logging meals to work pretty well. They’ve made a lot of changes to the app since then and it sucks now. The app is super glitchy now, particularly when taking my breath measurements. It gets so choppy and I’m convinced it doesn’t measure my breath accurately when it does that. Also, I can’t tell you how many food barcodes I scan these days that come up with “Sorry, item not found.” Seriously? Get it together. How am I supposed to log my food if half the bar codes I scan aren’t in your database? And the food photo feature used to work well and doesn’t work well at all. I’ve had it misidentify food to an embarrassing degree more than a few times. I don’t know what you all changed from how the app was a few years ago, but I beg of you, change it back. This app is becoming almost unusable and I’m about to bail on it. This isn’t the only app in that logs food so why would I continue to use one so riddled with issues?

Helpful and seems accurate

The device reads really seem accurate and when i consistently measure it’s really helpful and motivating data. Worth the price.

Not functional

I have been trying to reactivate my membership and already have a lumen device. I keep getting a white screen and broken links in the app when i was trying to restart membership. Also sent multiple messages to support and still have no resolution- i can only get the general readings, and when i try to sign up for membership through the app keep getting a 404 broken links message. It just does not work.
