EFB Application name and version: foreflight and flight plan go

Please include a detailed description of your issue or question: relative altitudes of other aircraft appear to be relative to the baro preassure altitude and not geodetic altitude. With a pressurized cockpit this is a significant problem.

Which EFB application are you using? Some allow you to select the altitude source. We will add a switch to the next iteration of the software for users who have pressurized aircraft.

Thanks, a switch for altitude should work fine. I saw your request for help and am interested but unfortunately my work keeps me on the road for 2 to 3 weeks at a time with 1 week at home. I also have several software projects in progress at work.
