What is the difference between web apps and cross-platform APP development ?, Webapp
What is a web app?

WebApp is a Web-based system and application. It is used to publish a complex set of content and functions to a large number of end users.
It is easy to understand because the mobile Internet is particularly popular. Many enterprise companies want to own their own apps, but because native app development costs are relatively high, in addition, post-maintenance is difficult. These development costs and post-maintenance costs cannot be used by individual entrepreneurs or start-ups in the early stage. Therefore, we are looking for a way-web app! The so-called web app adds a shell to the web site. It looks like an app can be uploaded to the app Store and downloaded from it, but what we see after opening it on our mobile phone is actually a webpage, but it is written as an adaptive webpage that can be displayed on our mobile phone. It can be used by others to make it look like a native app! However, the web app cannot obtain the underlying functions in the mobile phone, such as opening the camera, opening the album, obtaining our geographic location information, and paying... if you want to develop an app that requires native underlying capabilities, the web app will not be able to meet your needs, if you want to develop an app and upload it to Apple's app Store, it won't work. Apple's review is very strict, in Apple's opinion, web apps are not really apps at all. They can also be used as enterprise products.

What is a cross-platform app?

The so-called cross-platform app development is a set of code that can be released and run to various platforms on multiple terminals after writing, such as Android, iOS, js sdk, web, Baidu express account, and 360 stream applications...

 

Why is cross-platform app development required?

 

The UI for cross-platform app development is based on html5 css3 and js. Engineers can easily learn cross-platform app development with only the frontend, greatly reducing the app development cost, I don't know how much it costs to develop an app? If you want to develop an app at least yuan, the cost is not a small amount for individual entrepreneurs or startups, this number may be their monthly income for catering in Tier 3 cities. It may be unrealistic for them to develop an app with a month's income, after all, we don't know how much we can return after we put this thing on the market. I believe no one is making such a investment in these cases, after using cross-platform app development, it will be totally different. Finding an engineer to develop these terminals will take less than a month (for iOS Android js sdk web 360 stream app Baidu express code) the cost is very low when it is all developed. If you are a front-end developer and want to start a business as a project, it will be easier and the cost will be lower.

The most recommended is to read some cross-platform development books, most of which target all APP terminals.
