What apps are called artifacts in your mobile phone?

I feel that my mobile phone is full of artifacts, hahahahahaha, because I like to collect these useful apps. Today, I will introduce two.

The first one is called "pottery", which is a rebate for buying things on tb. You add your favorite things to the shopping cart on tb, and then open it with a Taobao. Every product will have a rebate amount, which will arrive half a month after the receipt is confirmed, and the amount can be deducted in the form of Jibao.

The second one is called "dir", which was recommended for download in an official WeChat account. I don't know if it can be found in every mall, but it's really useful. It is a garbage cleaning software. It is more powerful than the cleaning function of your mobile phone, which can make a lot of space for you in an instant. I like it very much, really.
