From iApps Pty Ltd:
FINALLY the Electronic Flight Bag app you've been waiting for!The FIRST and ONLY app to include a FULLY CUSTOMIZABLE LOGBOOK!This program was a collaboration of pilots and programming professionals so we hope it will cater to all needs and make flying easier both for Professionals and Hobbyists alike. This is just the first release with many more exciting features in production due for release soon within flightBOX. Our education section will allow students to hone skills and recap knowledge based items while it is great for the experienced pilots who would like a recap before there next renewal. FlightBOX will also have a easy to use yet comprehensive flight planning section for release in the coming weeks that will be useful for the private weekend pilot up to commercial operators. Here at FlightBOX our goal is to make this the first and last source for aviation information and flight related activities so we are interested to hear feedback and suggestions on what you would like to see as this is designed for you....THE PILOT!
