Need help ! – Barometer & Altimeter Pro Review

So far this APP works great, has never crashed, and give me what I THINK I need. I say, "what I think", because I am a novice. I really don't understand "Station Pressure/Altitude", nor how to set it and why. I know that this is just my ignorance, but it sure would be nice to get some help/essay explanation, etc. so that not only could I set it properly, but more importantly understand what I am looking at! Call me ignorant ... thats ok ... I am! ?. But, the way you get more, NEW users of an APP, is to help those of us that have an interest in understanding pressure and altitude ... what their interrelationship is and how to get accurate readings ! All I know right now, is that my joints start hurting when the pressure drops! It's "accurate" for me to take one more ibuprofen when that is about to (or even already) has dropped. Please help educate me to set this properly for my statistic elevation here in Rio Rancho, NM (5282')
