iTriage is something you should consider having on your iPhone and iPad. This is one of those apps I call the "odds and ends". It is not a note taker nor a game, it is listed under Health and Fitness in the Apple store.
Let's start with the Symptoms Checker, which has a human figure and with a tap you can change to female or male which also can be flipped from front to the back of the body. There are a multitude of symptoms given in a list form or you can do a search. But,when you tap on a certain part of the body it brings up the symptoms list and I like that better. You can narrow it down to a more detailed symptom.
