With the technology development, the life of tourists has become much easier. For example, if earlier buying a ticket for a train or plane was a whole event and took a lot of time, now it is enough just to open a mobile application, make some simple actions - and the tickets are yours. In addition, the need for paper maps, which used to be irreplaceable helpers of people in an unfamiliar place, is no longer needed; there is no need to pre-compile a list of attractions that you would like to visit and to carry a dictionary with you. Now, the best friend and your guidebook may be your smartphone. It remains only to determine which applications will be the most useful in the journey.
