Senosis' apps use your phone's sensors to check pulmonary function and hemoglobin counts

For those with limited access to medical services, one of the biggest challenges is getting screened for certain potentially life-threatening ailments. Shwetak Patel, a computer scientist at the University of Washington, wants to make this easier with a device most people already have: their phone. Senosis Health, a startup co-founded by Patel, has a number of apps its testing that use smartphones (and some not-so-smart phones) in unique ways for various medical applications.

HemaApp, for instance, measures hemoglobin in the blood using a smartphone's camera, which could help to detect conditions such as anemia, malnutrition, and pulmonary illnesses, all of which impact hemoglobin levels. By removing the need for expensive and timely blood draws, HemaApp delivers immediate results and alleviates concerns about sample contamination or infection.
