Im using this app to help plan my trip to Rome. The automated itinerary is very nice and it is easy to add or remove attractions from the list for a custom travel plan. Excellent list of attractions, restaurants, etc. The ability to download other users shared places and reviews will certainly make this one of the most comprehensive and up-to-date travel guides available.
Ill update my review when Ive had a chance to check out the augmented reality and the GPS based directions, but given the quality so far I have no doubt it will be just as good.
