App 100_3x4Skye Gould / Tech Insider

With millions of apps at our fingertips, it can be harder than ever to find the best of the best.

Tech Insider is here to help, with our first annual list of the 100 best mobile apps in the world.

In this list you’ll find juggernauts like Facebook and Snapchat along with hidden gems that haven’t hit the top of the App Store’s charts yet. Every one of these apps serves a valuable purpose, making life easier, better, or just more fun.

Social networking is one of the largest categories of apps on this list — a mark of how much they're transforming human interactions around the world. On-demand apps are another category that has exploded in popularity, with a Uber creating a whole new economy.

We've also got apps for productivity, news and reading, health and education, entertainment and music, photography, travel, money, shopping and food, and of course, games. Keep an eye out for the Tech Insider "best of" badge in each category for the one app that stands out from the rest.

You'll find the full list below (or can jump to categories by clicking the links above).
