Testimonials
Virginia Voss
"I just wanted to say this app works great before I got my blood work done. This morning I took a test with your app and my hemoglobin came back exactly the same. Just wanted to give you good feedback."
Jennifer Masters
"This app has been helpful. I get blood work done 2 to 3 times a year. I use it to monitor my iron score in between labs. I have compared readings from this app with my lab results and it is almost dead on."
Lori Gray
"I have used you app 11.5 so yes I’m low and this helps me to maintain my iron before it gets too low! Thank you for this. If it is under 15 I try to eat more iron with my iron supplement to help maintain better health."
Sharon Graham-Mowry
"Fantastic app, a dream come true for me. I have hemolytic anemia, cold agglutinin disease. These are pretty accurate results I check daily. Thank you."
Gonzologic
"One week in and so far, it’s been super easy to use on a daily basis. I’m an athlete training for a marathon and sometimes my runs make me anemic. Testing before and after my runs is super useful as I manage my iron intake via diet and supplements. Thank you Ruby!"

"You have to create an account first but then it really does just take a pic of your fingernails (skin tone doesn’t matter) and give you an iron score. No needles!!!"

FAQs
What is Ruby?
Ruby is a wellness app that uses patented fingernail selfie technology to monitor blood health. It analyzes fingernail photos to estimate your Iron and Circulation Scores. It also offers features to track your mood, water intake, supplements and medications, and menstrual cycles—all in one convenient app.
Does it matter which hand I use?
No, you can use either hand. Choose the one that makes it easiest to take a clear, steady photo of your nail bed.
Can I use the app with nail polish on?
No, nail polish blocks our technology from accurately reading your nail bed. Remove all nail polish, including clear coats, before testing.
Does skin tone affect results?
No, Ruby is designed and tested to be accurate for all skin tones. Our technology specifically analyzes your nail beds, not your skin.
What is an Iron Score?
Iron score correlates to your likelihood of iron deficiency or iron deficiency anemia based on the paleness of your fingernail beds.
What is a Circulation Score?
Your circulation is a measure of how your blood is moving in your fingertips. The circulation score measures how fast your blood is moving in your fingertips.
