iFrog is a free application that can display animation of frogs on the screen of your phone. Just press "Show Frog" and give the app permission to draw over other apps. The application will start to display the animation and sound of frogs on the screen of your phone. The animation will be displayed in the foreground of all running apps. You can use your favorite social network, browse the Internet, or play a game and you will still see the small animal and hear their croak sound.

The application has an option to enable or disable the animation and sound. You can also adjust the time delay of the animal appearing on the screen.
