“The world is a book, and those who do not travel read only one page.” is said by Saint Augustine. So, we can say that Travel is an opportunity to read the world. You will find very few people who do not like traveling. Traveling helps us to refresh our minds. Through traveling, you might find a new, taste, flavor, scent, vision, or sound that will make your world a richer place. You might meet new people, form new relationships, find and discover new languages. There are many existing applications that are used to assist in travel. Some of the application shows the place for traveling, some others used for searching hotels, etc.

Besides all the mentioned functionalities, you have to add some other interactive functions that do not exist in any other applications.
