What are the necessary apps for smart watches?

At present, there are still few apps in the Android wear ecosystem, and there are even fewer domestic developers. Recommend several applications that I am using now:

1) Watch control: watches and thousands of dials can be activated quickly. There are also Chinese menus and Chinese pronunciations. The function of real-time weather is also good.

2) Wear a camera: a mobile phone camera that can be controlled on the watch.

3)Facer, custom dial

4)android wear WeChat, which supports Android wear WeChat and can push WeChat messages.

5)tic toc, playing tic-tac-toe on a watch can really attract a lot of people's attention.
