I flew today for the first time using my new pingBuddy. It seemed to work well with my iPad Mini 4 and iPhone 6S Plus. It did take iFly GPS about 30 minutes to start showing updated metars/TAF's while another app I sometimes use showed them much sooner. Also, for the entire flight I had the Target Altitude instrument displayed showing 1200+ regardless of what altitude I was at or whether I was using a sectional, WAC, or low altitude. I forgot what this instrument is supposed to show.
