Here is' a collection of the best travel apps.

Best for planning

PackPoint

The app customizes (定制) packing lists based on weather forecasts and a questionnaire about your trip — where you're going, when you're going, what you're doing, etc.

You can get all these features with the free app; but with a $ 2. 99 in-app purchase.

Best for your body

Timeshifter

The app offers advice about when you should expose yourself to bright lights, when you should avoid caffeine, and when you should nap. The best part? It takes into account your habits, routines, and sleep patterns as it devises a personalized jet lag plan for you. The downside? You only get one free plan. After that, it's $ 9. 99 per plan or $ 24. 99 for a year of unlimited plans.

Best for managing your money

GlobeTips

Different countries have different tipping customs. GlobeTips can help with navigating different tipping norms across countries.

Once you select a country, you have the choice to either manually enter the bill amount or let the app's bill recognition technology do it for you. Use the sliding scale to adjust tip percentages based on the app's suggestion, and it will calculate and display both the tip and your total. You can look at tipping basics for each country on the free version, but you'll have to upgrade the app for $ 4. 99 if you want to read the tip guide in full. This app is for iOS users only, however.

Best for local experiences

Meetup

Great minds think alike, and they get together with the help of Meetup. The platform is all about connecting people with similar interests. It has more than 44 million users and more than 333,000 meet up groups, so you’re bound to find something. Once you find a group that interests you, you can request to become a member and attend its events. The app is free unless you’re trying to organize groups and events yourself-in which case you'll have to pay for a subscription (订购) starting at $ 9. 99.
