We like Kayak for cars and hotels, but flights is where it blows us away. Monitor prices in a watchlist, view and import all your plans, track flights, and get security wait time estimates. Feeling spontaneous? Choose “Explore” and set basic parameters (say, a budget and temperature preference), then see what the map suggests.

With guides for over 200 cities, this Lonely Planet app offers the same kind of practical, well-researched information the publisher’s known for in print. Each city guide you open is downloaded, so everything – including pinned maps – is available offline. We’re big fans of the phrasebooks and neighborhood guides (though not every city has them).

Eleventh-hour escapes are this app’s sweet spot. You’ll find deeply discounted accommodations, categorized by quality and style – like “Charming” or “High Roller.” With certain bookings, you can connect to an in-app concierge for special requests and local tips. Note that some hotels won’t let you choose your room type, and cancellation policies are strict.

Solo wanderers and anyone eager to connect with new people will find much to love in this vibrant community of locals and travelers. If you’re on a tight budget or looking for a homestay experience, reach out to hosts to find a spare room (or couch). Simply looking for someone to explore with? See who’s available to “hang out now.”

This designed-for-travel journal lets you add multiple photos and a note to each entry. Save drafts of in-progress posts, and share each to the in-app community and social media, or privately with a secret link. Get longer battery life (at the expense of some location accuracy) by tapping “battery saver.”
