This fullscreen browser is "one-window" browser that opens pre-configured site (should be set in iOS Settings). The application allows to hide status bar and use top and bottom edges of your iPhone (configurable). 

Kiosk doesn't have any navigation bar to allow real fullscreen experience, you can use swipe gestures to go back/forward.

This app could be used with iOS Guided Access to open any educational sites for children. This way they will not be able to use other sites with this browser (option is configured via iOS Settings menu).

How to start a Guided Access Session?
* Open the app.
* Triple tap the side button if it’s iPhone X or later. Triple tap the Home button for iPhone 8 or later.
* Click on Guided Access > Tap Start.

Or simply
* Open the app.
* Ask Siri to “Turn on Guided Access”.
