Factorial Calculator, developed by Universapp, is an Android application that lets you calculate the factorial of an integer number, including large numbers, in a short time. It is a convenient tool that can be used for studying, researching, or any other purposes. With smart algorithms, the app delivers fast and accurate results, making it a reliable tool for all your factorial calculation needs.

The app has a modern and intuitive interface that allows you to choose between light and dark themes. It offers various features, including the ability to show the result in scientific notation format or fully digits. You can change the minimum format number on settings, and the app will show the result accordingly. Moreover, you can copy the output and turn on the instant run feature to compute simultaneously as you type the number.

Factorial Calculator is a lightweight and easy-to-use app that provides a smart and fast way to calculate factorials. However, note that displaying the full result of more than 100,000 digits could slow down the app's performance. You can turn off showing the full result on settings to keep the app smoothly if you don't need it.
