Iphone only has its own camera, and there is no special self-timer software. If you are a girl, please recommend some reusable software that can be downloaded from the app store:

Nice, a famous marking software, and the filter is also very nice.

In spring, you can slim your face, increase your height in proportion and make people thinner. It is the most effective slimming model used so far.

Rookie cam, the best filter software, has all the filters used by red people in Weibo, so you don't need to buy the full version. Especially recommend the photo frame inside. The paid photo frame inside is super beautiful and I have been reluctant to buy it.

Instagram, the famous ins, is used by many international stars. To tell the truth, the filter is similar to a rookie, and you have to download vpn to match it. Very tasteless.

Snapseed can partially whiten, increase contrast, etc., and whiten the supernatural.

Professional software Picsart, fully functional.

Playing with pictures is a good educational software, and the photo frame is very beautiful.
