Ads Practically Yell at You. EVERY SCREEN in the start up process had display blocking pages warning "save your health" by buying into their pay service (sorry, I have a doctor, I don't need an an app diagnosing me). Had I seen ONE screen of their app, I may have been able to decide whether I would like to use it. BUT if this is how they treat people while trying to earn their business, and TRUST, no thanks. Learn some manners, and sell your app on it's merits. It felt like a used car lot.
