为促进数字经济发展、保护个人信息安全,公安部会同有关部门组织建设了国家网络身份认证公共服务平台,向社会提供安全、便捷、权威、高效的网络身份认证公共服务。 国家网络身份认证App是国家网络身份认证公共服务平台的移动客户端。 个人用户可下载国家网络身份认证App,使用法定身份证件申领网号、网证,即可在不输入、不留存、不透露个人姓名、公民身份号码等明文身份信息的情况下完成身份认证。
Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be. The 4 screenshots above are 国家网络身份认证's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: 国家网络身份认证 runs a light set with one background colour (#FCFCFC) carried across every screenshot — the listing reads as a single poster when the shots sit side by side in search results. The accent colour we picked up, #0C3484, is the one to reuse for badges, arrows and highlighted words if you borrow this look. Hit Use this style to open the editor with these exact colours and drop your own screenshot in.
Notice the first screenshot in particular. It's the one users see in search results and on the product page, and it's where most apps spend their best caption and tightest design. Look at the proportion of background to phone, where the text sits, what one thing the image is trying to communicate.
