Tripit – TripIt is a free travel organizer app. You’ll never have to dig through your printed, paper itineraries again. TripIt links to your e-mail account and picks up every confirmation number that comes into your inbox. Any flight, hotel, or even dinner reservation that contains a confirmation number will be put into an organised itinerary. It’s very simple and super handy. One of my favorite app that I discovered lately.
Kayak – The easiest way to search for flights, hotels and car rentals all in one place.
Google Maps – this doesn’t need an explanation.
Google translate – This app translates between 64 languages, and can deliver audio translations for certain one. It doesn’t always get the translation right, but is probably the most comprehensive translation app out there.
Skyscanner – Price-comparison website to see all the cheapest flight options around the dates you want to fly.
TripAdvisor – Ultimate travel compendium! Many hotels, restaurants, flights and points of interest and access to all the websites ratings, reviews and recommendations. I recommend sharing your own reviews with users and you will make sure your voice will be heard.
Airbnb & Hostelworld – Not everyone who has a smartphone can afford to stay at a hotel every night, so those handy apps with budget hotels is a great tool.
XE Currency – app calculates and makes conversions for you instantly using up to 180+ worldwide currencies.
Clear – it’s a kind of super simple and well designed “to do” list. I use it all the time and not only for travel. But especially it comes handy when you have to pack and make sure nothing is missing.
Other apps that I use very often on the road:
Communication apps like Whatsapp will let you stay in touch without high phone costs
Photos apps: Instagram, Flickr
Blog apps: WordPress and Blogsy
Reading: kindle, audible
