The world health organization estimates that anemia affects 1/4 of the world's population.
Here is Phil's story:
"I, as well as 1 in 200 people in the UK, have the opposite problem - a generic disorder that causes elevated iron levels.
My wife is currently pregnant and at a higher risk than the general population for low iron levels.
So we are both examples of the population that could really benefit from being able to track and monitor iron levels, which is what this app allows.
But it's bigger than that. This platform will enable anyone wanting to monitor their own health - either representatively or for a particular disease or symptom - to be able to do so."
