Its ok.

The app was not very helpful for me. When I put in the symptoms it gave me dozens of different diagnosis with only 1 or 2 of the symptoms attached. It needs to be like the human checker where it gives you percentages of chance that it is a certain diagnosis. And the first few always seem extreme like cancer, deadly virus. Yet it turns out just being a allergy.
