题目内容：

If you like to check your smartphone from time to time, you are not alone. In fact, using apps（应用程序）has now become part of everyday life.

Changba

 

Changba, which has been described as "the best mobile karaoke for sound", allows you to sing along to over 2,000 songs. You can also share your KTV recordings with friends on social media sites such as Weibo, Wechat, Qzone, etc. The app allows users to create a photo show to go with their songs and comment on other people's songs. Changba can even filter the sound. For example, it can make cat noises sound like a beautiful chorus(合唱).

Moment Cam

 

Moment Cam brings you some of the most useful features a camera app can have, such as adjusting the flash(调整闪光灯）,continuous shots, adjusting the timer, and choosing different sizes for photo-sharing sites. But what sets the app apart from all the others is the choice of simple mini-buttons that you hardly notice are there.

Carrot

 

Carrot, a to-do list app, is a task manager with a personality, When you succeed in finishing your tasks, for example, Carrot praises you with a message such as "Way to go. Soon you'll be completing other people's to-do lists".But if you fail to perform your tasks, Carrot might say, "I'm angered at your behavior." And it may change its background from white to black to show how angry it is. So, if you need an extra push to finish your tasks, give Carrot a try.
