Pretty good start, significant bug

There is a serious bug: the altitude setting does not work. The entry makes absolutely no difference to the calculations. The work-around is to enter the absolute barometric pressure at your altitude. This is NOT the pressure you get off the weather report, which has been altitude-corrected to sea level. You either have to have a barometer with you (e.g., Kestrel 3500) or do the calculations to correct the weather report data to your actual altitude. (I have not found an app that will do that for you.) This should be an easy fix, so I look forward to the next version.
