Who can be expected to remember all the potential symptoms of the thousands of diseases that exist? It is equally impossible to memorize the utility of the tests designed to diagnose these diseases.

Let this app help you keep all that information on hand, at the bedside:

- Forgot what the symptoms of hypomagnesemia are? Find them with a few taps.
- Create a differential diagnosis from a list of hundreds of symptoms on the fly.
- View the diagnostic accuracies of hundreds of tests quickly and easily, so you never order a useless test again.

The app withholds most features until a subscription is purchased.
