The most powerful and popular mobile development tools without code are Adalo, Glide and Bubble. With their help, you can create and publish a mobile application. They come in three types:
The mobile version of the site is a website on the Internet adapted for smartphone screens
This is the most “disenfranchised” type of application: you always need the Internet, push can only be enabled in the browser, browser navigation elements are constantly visible.

PWA (Progressive Web Application) — when the mobile version of the site is installed on a smartphone as an application. One of the advantages is that there is no need to support two code bases, for iOS and Android, the application is always “updated” to the latest version, you can work with some native smartphone functions. For example, sending push messages, setting a shortcut to the screen, browser navigation elements do not interfere (they simply do not exist). such applications can create Bubble, Adalo, and Glide.
Native — when the application is published in the official stores. Adalo already has such a feature built in, and Bubble apps can be wrapped in a special container and also published on Google Play and the App Store. Native applications allow you to work with all phone functions: camera, microphone, GPS, contacts, files, accelerometer, push notifications, device memory, adaptive layout – everything is as in the usual code, only without code.
