Baidu is China’s most popular search engine, often called the Google of China. Baidu was founded in 2000 and has products in advertising, maps, news, autonomous driving, artificial intelligence and more.
‍

Baidu's iOS app has a bunch of features including search, weather, news, audio content, videos, user generated content, mini games, cab search, hotel search, train bookings, restaurant search. These are bundled within the main app and are just one or two taps away.

The touch point on the top right of the home page takes you to a list of competitions.

Each competition is almost its own mini app. Some require you to play a mini game, some make you invite as many friends as possible and compete on a leaderboard, some make you do tasks, some are a lucky draw and so on. You can win money, electronics, mobile data, and so on

Some of them have multiple editions and run for weeks, some are special promotions.

When you’re on mobile data or if your WiFi is not working, it enables data saver mode. Clicking on videos shows file size and asks for confirmation. You can either continue watching or buy a data pack that lets you stream videos from certain apps, including Baidu, for free.

The home page's main call to action is Search. Under it, there are configurable tabs for topics you want to receive news from. The top navigation shows the weather and a way to access mini apps.

The bottom navigation's main action button is voice search. At the time I documented this, the other tabs were Home, Video, Bookmarks and Profile. These usually change often, probably as a result of A/B testing.

The main call to action on topof the page is to sign up via phone number, WeChat, QQ or Weibo.
