About this app

AnemoCheck is the FIRST smartphone app that gives you your Iron Grade*.

Have you experienced dizziness, fatigue, or frequent headaches? Ever wondered how much iron you need in your diet? AnemoCheck makes it easy to instantly track your iron levels with one simple fingernail selfie.

1. Download the app

Featured in Forbes, Business Insider, Bloomberg, TechCrunch, Fast Company, Associated Press, and BBC.

*What’s an Iron Grade? It’s a non-invasive hemoglobin estimate based on a picture of your fingernails combined with a log to track your nutritional intake and mood. Not getting enough iron, folate or vitamin B12 in your diet may cause:

💅🏼 Brittle nails
😴 Fatigue
🏋️ Physical weakness
🎈 Lightheadedness
🥴 Dizziness
👱‍♂️ Pallor (Pale or yellowish skin)
💨 Shortness of breath
🤕 Headaches
🥶 Cold hands and feet

• Allows you to track your folate, vitamin B12, iron intake and mood for the day.
• Gives you an instant Iron Grade with just a fingernail selfie
• Saves your history in shareable format

AnemoCheck now offers a premium subscription that includes the following features:

+ MyMobile – Get 50% more accurate results with your unique algorithm. It calibrates every time you upload lab tests and take a fingernail selfie.
+ Unlimited tests - You can test as often as you want to get a better idea of how diet and lifestyle changes impact your Iron Grade.
+ Data insights - You have full access to past test results. See how your Iron Grade has changed over time and track trends such as your mood and supplement use.
+ Set reminders - We know life gets hectic, and we can help you tap into your health by sending you reminders on when to take your fingernail selfie.

AnemoCheck is perfect for:
• Women, especially those who are pregnant or have just given birth
• Parents of young children and infants
• People over the age of 65
• Vegetarians & vegans
• High-performance athletes
• Anyone managing their nutritional intake!

Wish the accuracy was better. My doctor was interested when I mentioned this app and we did a test on the app in office since I was having iron added to my bloodwork at the time. It was so off! Nearly 3 points off. My office bloodwork showed severe anemia, the app said I was fine. Been using it for a few months and it was spot on three months ago, not so much now. ETA: putting algorithms behind paywalls doesn't help the average user who is using the app to monitor between Dr visits as I was.

Hello- We’re sorry to hear you’re having issues using AnemoCheck. In addition to taking fingernail selfies on our app, we recommend adding your lab results to help improve your algorithm. Please keep in mind that AnemoCheck is intended to be a wellness/healthy lifestyle tool and should not be used to replace blood tests or make medical decisions.

What happened!?? Everything requires a premium membership now so I can't even see my average level anymore. Big fail on your part in my opinion. That was the main reason I liked this app. Well it's not worth it to keep anymore if all I can are my most recent entries. What a waste!

Even though it uses the flash, it seems to be really sensitive to the ambient light in the room. Just tested in a sun-lit room (well lit but out of direct sunlight). First reading was 10.5. Standing in the same spot, I turned 90 degrees and tested again. This time it was 12.6. Interesting research though.

Hi Doug, I'm sorry to hear you are getting inconsistent results. Take a look at our instructional video for tips on taking the best picture( Consistency helps as some lighting conditions are simply too powerful to overcome even with the flash. Please let me know how it goes at Best, Rob
