TripTic Freemium

My travel app. ‘TripTic’ is now free with an in-app purchase for unrestricted use. Existing owners get full version.
New features include single file backups and sharing of site categories via email or AirDrop. See TripTic 1 5 - YouTube for video and TripTic for more info and other videos.
Thanks to the fantastic tutorials here for getting me through the in-app purchase capability and the ability to check and validate receipts so that those who already purchased when it was a paid app, get the full, unrestricted version.
