Do you know any way or trick to convert a website to android and ios app?

You should try capacitorjs.com/

It works by "wrapping" your app in a web-view and "generates" the needed code for it to run on IOS and Android. Its very easy to use, very friendly and you should be done in a couple of minutes.

Take a note that this way your app is not going to be NATIVE, because It would run inside a WebView inside the mobile OS, but performance would not be a concern, taking in mind that you want to transfer the existing web behavior in a mobile app.

Now, if you want to add more native-like functionalities or add CPU intensive logic, you should look elsewhere, but if using an existing web app on mobile is what you ask, you won't have any problems!!

Take care!

Make a PWA?

The question of how to convert website to ios app currently arises for many people, because mobile applications are becoming more and more popular. In general, there are many online converters. These services offer you to turn your existing website into an iOS app. However, you may not be satisfied with the end result. Usually, such platforms simply place the site in a WebView wrapper. Thus, the UX is not user-friendly at all. It is better to work with an experienced iOS app development company that will fulfill all your requirements and can develop an app that meets the expectations of your customers.

I got you buddy :) codecanyon.net/item/prime-web-conv...

There's probably also free alternatives, but this one works great and has a lot of good reviews. Definitely worth the $7 (currently on discount) price ;)
