Dangerous app
My hemoglobin is 29.3 and ferritin is 5, but Ruby Health stops at 26 and claimed I am not anemic. I am medically diagnosed with severe anemia. I got this app to show my progress, but based on my experience this app is unsafe for anyone tracking their condition.
Does not seem to be reliable
I wanted this to work so I knew if I need to adjust my iron intake. I did this test two days in a row and there was a 2 point difference. The lower of the two numbers was done in my bathroom which has what claims to be a daylight light bulb and the higher number was done in a room with a standard led. I do the free version so I only use it when I feel off and need to know if it is iron or protein I need. hopefully one day this can be a lot more accurate because right now they're really aren't at home tests unless you get it from a different country and or pay an arm and a leg and I'm not going to run to the doctor every time there's a problem because it's pretty much pointless for a female in the US.

Response from developer
Thank you for your feedback! As you mentioned, lighting significantly affects accuracy. A 2-point difference between lighting conditions is within the expected range. For the most consistent results, test near a bright window with indirect natural light, as shown in our tutorial. Our Premium calibration feature can also improve consistency by personalizing the app. Email support@sanguina.com for additional tips. We're here to help!

Lighting is Key
Depending on lighting the results can be wildly different.
App need to control for lighting or advise user as to lighting.
