If anyone in Hawaii is going to AirVenture Oshkosh this year, and wants a better system for planning your itinerary and seeing your itinerary than the EAA web site and its companion mobile app, drop me a line at firstname.lastname@example.org. I wrote my own app for managing my AirVenture schedule, which I have been using for the last 3 times I went. It shows your selected items as stacked time lanes, i.e. for allowing you to make choices between overlapping schedules, avoiding back-to-back presentations at opposite ends of the field, etc. and quicker and easier viewing of topic descriptions. It requires a Windows system though, but it creates an html document with your itinerary that you can take with you and view on any device. Making it as a mobile app was not feasible for me for reasons I won’t bore you with. I would happily provide the app for free to anyone who wants it. I can’t attach it as I’m sure this forum won’t let me attach executables due to virus risks.
