What are the treasured apps in your mobile phone?

? I do have many applications in my mobile phone ... Let me recommend some mobile apps that are not very popular but very practical!

Library. There are many books in this APP, all of which are very nice. The most important thing is that you can read some books without spending money, which is one of the reasons why I love it. Unlike other reading software, you need to spend money to buy or open a member to read the books you want. Very practical!

? Netease cloud music. I have used this music player for a long time, and I can be said to be a big fan of it. Now many people generally like to use cool dog music, QQ music and other players, but I recommend you to use Netease Cloud. Its entire APP design is my favorite, not as many beautiful themes as QQ music. There are not many themes, but they are simple and elegant, and there are many ancient songs in them. You can also listen to some radio dramas and cross talks, which are very practical.

Finger. I stumbled across this software, because I always wanted to learn guitar, but it was zero-based, so I looked up some tutorials on the Internet and found this APP. It can help us learn all kinds of musical instruments, even a novice with zero foundation like me can try to learn. So, this software is really practical!

Smart ID photo. As soon as you hear the name of this software, you will know what it is for. You can download this software with your mobile phone, so you don't have to spend a lot of money to take those ugly photos in the photo studio every day. On your mobile phone, you can make it beautiful!

There is an interpreter. This is an English learning software. I think this software is really super practical for some people who want to learn English. It can translate English into Chinese, Chinese into English and photos. Is it super practical?

Are these apps I cherish very practical?
