Recently travel to Greece and Turkey for 12 days. This is great app. Rather than using a travel agency, we have decided to explore and book every single excursion, hotel, activity, flight etc. by ourselves. Without these applications, I would have had tons of paper in my folder to carry around in my backpack.This is very smart app, automatically organizes your activities starting from parking at the airport with the address of parking spot at the airport, flight details, car rental, hotel detail, check in date, check out date, including flight confirmation number, hotel confirmation number etc. in a very systematic manner. I was highly impressed by this application and its functionality. And also it is completely free to use. I did not pay even a dime to use this application. I am also fascinated by his function regarding local transportation. As soon as I reached at the Athens airport say for example, it also gave me different options to go to my hotel from the airport including public transportation with 100% accuracy. I have become a big fan of this application. I will use this application every time I travel in future. I was somewhat hesitant to provide complete authorization for this app to go into my email account to pull itinerary by individual emails. Other option would be to send individual emails to the app. I guess I was too lazy to do that so I gave complete access of my email account to this application. I believe it should be safe.
