Device works well but after purchasing the device some users still have to pay the subscription for it to work even though you purchased the device up front. Other users only have to pay for the additional features and can use the device without the subscription depending on the version you have.

poor. it wants me to enter my last mean but the only option its giving me to choose from is yesterday n today. well I've been fasting over 36 hrs , lumen says it can't give me a good insight till I put in my last meal. So its poorly designed.

little by little helping me understand how my body is processing what I do and what I eat.

I switched my phone from Pixel 7 Pro to 10 Pro. Now I have to sign in every time I open the app. Email and password. Annoying. I contacted support but have received no answer for a few days. :( [UPDATE] I still cannot locate the original message but did receive a follow-up message. But no resolution yet.

I home after a errand to do my post lunch breath, and when I started the app it offered to do a breath, which I assumed would be a post-meal breath, but it tagged it as "wake up". So here I am with the app changing my meal plan in the middle of the day. This is the third time a breath has been miscategorized and I thought that perhaps it was my fault, but now I don't think so. Apparently the feature edit breaths has been removed. Stop dumbing-down your app, give us access to CSV exports.
