Random Number Generator - Easy is a free iPhone app developed by Kevin Horvath. It falls under the category of Utilities & Tools and offers a simple and elegant way to generate random numbers.

One of the standout features of this app is the rotating colors that accompany the generation of new numbers. If you find the colors overwhelming, you can easily turn them off in the settings screen, as the app provides full configurability.

In addition to visual effects, Random Number Generator - Easy also offers sound and vibration options. By enabling these features in the settings screen, you can hear a sound and feel your device vibrate with each new number generated.

Copying the generated number to the clipboard for use in other apps is a breeze. Simply tap on the generated number and it will be automatically copied.

The app keeps a history of generated numbers, including the date, time, and the minimum and maximum values used. This history can be accessed at any time until it is cleared.

To prevent duplicates from being generated, the app offers a 'Prevent Duplicates' feature that can be enabled in the settings screen.

Random Number Generator - Easy provides a straightforward and customizable solution for generating random numbers on your iPhone.
